These Quality and Testing Regulations have been established by RAL Deutsches Institut für Gütesicherung und Kennzeichnung e. V. (RAL German Institute for Quality Assurance and Labelling) under the principles for quality labelling in a recognition process together with expert groups and responsible authorities.
Bonn, January 2022
RAL Deutsches Institut für Gütesicherung und Kennzeichnung e. V.
RAL-GZ 430 has been the “gold standard” for good furniture quality for more than half a century. However, its contents require constant adaptation in order to meet the needs of changing consumer requirements on the one hand and technical as well as social developments on the other. Standards, laws, and other recognised rules of technology are constantly changing. They are an essential part of RAL-GZ 430, which in its quality requirements, however, often goes beyond normative basic requirements.
With the claim of a holistic quality standard for furniture, RAL-GZ 430 includes in testable form the topics of processing quality, utility and comfort, product safety, healthy living as well as sustainability in product design and material selection.
The previously proven requirements and test methods have been adopted largely unchanged in this new edition of the RAL. In detail, however, changes, updates and adaptations were necessary, based on the experience in dealing with this set of rules and due to changes in standards which are referenced in this RAL.
As the person responsible for the editorial processing of the results of the DGM working groups, I would like to express my special thanks to the staff of these working groups as well as to the editorial team of the DGM. Without the dedicated cooperation and competent contributions of the voluntary DGM working group participants, further development and updating of RAL-GZ 430 would not have been possible.
Reimund Heym Head of Technology and StandardisationIt all started with RAL-GZ 430. It is the basis for the “Golden M” certification, which focused on quality, function, and environmental compatibility early on. It was and still is a matter of consumer protection.
I am all the more pleased that the Deutsche Gütegemeinschaft Möbel e. V. recognised early on that quality, and thus durability, is an essential part of sustainability. Various certification offers in this area followed, whether it was climate neutrality or emission measurements of the products. Then, in 2019, very consistently, the Advisory Board for Sustainability was founded to meet the everincreasing pressure for change, which was also of a legislative nature. Today, sustainability is no longer a trend, nor is it a megatrend, but a must, an imperative.
We need to recognise that companies are part of the environment and part of society, that we are all part of a system with interdependencies, no matter what we do or don’t do. Sustainability management is a journey that never ends for companies. With its various certifications, the DGM offers companies goals and intermediate destinations for this journey, and thus also offers the end-consumer reliable information on the subject of sustainability. With this in mind, I am honoured to be able to shape the future with the wonderful people on the Advisory Board and I look forward to continued constructive discussions leading to results for the good of all.

These Quality and Testing Regulations apply to the condition of furniture for the office and contract sector 1 that may be labelled with the RAL quality mark. All legal regulations must be observed as a matter of principle. In addition, quality assured furniture must meet the requirements as defined below. All standards relating to the scope of these Quality and Testing Regulations shall be consulted as well.
Only the most recent versions of standards or their relevant replacements are valid.
The requirements take into account as standard climate according to DIN 50014 a temperature of 23° C and a relative humidity of 50% and apply to furniture in new condition.
At the time of publication of these Quality and Testing Regulations, the DIN 68890 standard is being revised. Upon publication of this standard, the requirements contained therein shall be considered binding, provided that they do not fall below the values specified in these Quality and Testing Regulations.
Proper transport and professional assembly of the products are assumed.
The basic requirements for quality assured furniture are regulated by the relevant standards and guidelines of the Quality and Testing Regulations, compliance with which is mandatory as a prerequisite for initial testing according to Section 3.1.
Furniture that contains functional and constructional elements not included in RAL-GZ 430 must conform to current technological standards
Monitoring is divided as follows:
• Initial testing
• Internal quality control
• External quality control
• Repeat testing
• Testing and monitoring reports / Approval license
• Testing costs
1 Where the term office furniture is used below, this also includes furniture for the contract sector.
3.1.
• Inspectors
Passing the initial test is one of the requirements for the award and use of the quality mark of the Quality Association. Initial testing is carried out in the production facilities of the applicant. As part of this assessment, random laboratory test samples are taken from ongoing production by the commissioned third-party inspector. If the applicant can provide test certificates for supplied products or materials, the test procedure is reduced. It is, however, important that these documents (test certificates may not be older than 1 year) are based on the current technological standards and the tests were carried out by competent and neutral testing institutes.
3.2.
Ongoing internal quality control, which can be reproduced at any time, is mandatory for all quality mark users. Users must carefully record the results of internal quality controls, keep them for at last 5 years and present them to the appointed inspector for inspection upon request within the scope of external quality control procedures
3.3.
In order to ensure the consistent quality of quality assured products, external quality control is carried out every 2 years on the premises of the quality mark user. Within the first 3 years of awarding the quality mark/membership, external quality control is carried out annually. This test covers the inspection of the results of all quality control measures (e. g. internal quality control, test reports from competent, neutral testing institutes) and the inspection of the proper manufacturing of “quality assured office furniture”.
3.4.
If deficiencies in the quality assurance are detected during external quality control measures, the Quality Committee can order a repetition of the test, whereby the type, content and scope of this test are determined by the Quality Committee of Deutsche Gütegemeinschaft Möbel e. V. Should the repeat test also conclude with a negative result, the Quality Committee may, in agreement with the Executive Board, take further measures in accordance with Section 12.5 of the Implementing Regulations for the Award and Use of the Quality Mark
3.5.
The contracted external inspectors must draw up corresponding test reports on the tests and quality control procedures carried out; the applicant or quality mark user each receive copies of said reports.
Based on the passed tests, the DGM office issues an approval license for the furniture programs listed therein for a certain term
3.6.
The applicant or quality mark user must bear all arising testing or monitoring costs.
3.7.
The Quality Association appoints suitable, expert testing institutes to carry out tests and monitoring measures.
Institutes entrusted with this task must prove their identity to the applicant or quality mark user by submitting a written identification before starting their work.
Sustainability is to be understood as a development that is ecologically compatible, socially just and economically efficient.
Important in this context is a long product life, which can only be achieved through high quality, which contributes significantly to saving resources and which is therefore an essential part of sustainable economic activity. Another aspect of sustainability is the consideration of social impacts.
Sustainability as well as the environment and personal health are particularly important to consumers today. In close cooperation with leading testing institutes and taking into account more recent specifications of the Federal Environment Agency, the requirements were revised and adapted to the latest scientific findings.
These requirements apply to office furniture as purchasable by consumers in furniture stores. Manufacturers must ensure that all supplied materials (including those from abroad) comply with the statutory European and German regulations (e. g. Chemicals Act, Banned Chemicals Ordinance and Ordinance on Hazardous Substances, REACH POP) as well as additional DGM requirements.
In case of mandatory normative, legal, safety-relevant as well as contractual specifications regarding the use of materials, substances and requirements, the effects on the requirements according to RAL-GZ 430, especially in the contract sector, are not taken into consideration.
The initial and monitoring tests are to be carried out according to Point 3
The preparations (paints, adhesives, stains, coatings, etc.) must not contain substances of the following categories as formulation components:
Substances according to Regulation (EC) No 1272/2008 (CLP Regulation):
Categories Carcinogenic 1A and 1B, Mutagenic 1A and 1B, Toxic to reproduction 1A and 1B
a) Sensitising substances according to the Technical Rule for Hazardous Substances (TRGS) 907 and the EC Regulation 1272/2008, Annex VI
b) Substances which are of very high concern for other reasons, and which have been included in the list (so-called candidate list 1) established in accordance with REACH Article 59(1)
c) Acutely toxic (poisonous) of the category Acute Tox. 1 or Acute Tox. 2
d) Toxic to specific target organs of the category STOT SE 1, STOT SE 2, STOT RE 1, or STOT RE 2
Excluded from these regulations are:
a) Process-related, technically unavoidable impurities that are below the classification limits for mixtures.
b) Monomers or additives that react to form polymers or are chemically bonded (covalently) into the plastic during plastic production if their residual concentrations are below the classification limit for mixtures.
4.1.1.
The examinations in test chambers can be carried out both as whole-body tests and as component tests. The selection of test samples is to be agreed between the testing institute and the manufacturer and is to be carried out in such a way that all model variants awarded the quality mark are represented by the test
4.1.2.
The final products falling within the area of application differ in shape, materials and the number of materials used. Therefore, in each individual case, the test procedure and the selection of test samples must be determined by the testing institute responsible for the surveillance test in consultation with the manufacturer.
For furniture made of wood and wood-based materials with a three-dimensional surface, there are two ways of testing:
a) Whole-body testing, especially for small furniture, chairs, etc.
b) Component testing, especially for modular furniture and furniture programs with similar components.
1 Link to the candidate list of Regulation (EC) No 1907/2006 on the Registration, Evaluation, Authorisation and Restriction of Chemicals (REACH): https://echa.europa.eu/de/candidate-list-table
4.1.2.1.
The product to be tested must be taken directly from current production. Supplied parts may not be older than 10 days. A deviation from this specification is permissible if the manufacturer proves that individual supplied parts used in the normal production process are regularly older than 10 days.
Immediately after removal from production, the product must be placed in airtight packaging; modular furniture must be packed in closed state.
Note:
During component testing, it is permissible to use the following calculation formula to extrapolate the total concentration of complete products consisting of known area segments of the tested components, based on the established concentrations of volatile organic compounds of the individual components.
The proportionate areas of the total product must be calculated for each component and entered into the formula with the emission values determined:
Ccalc. = Calculated total concentration for complete product in µg/m³
n = Number of components tested
i = Compendent index
Ai (%) = Area share of the i-th component in %
Ci = Concentration of the i-th component in µg/m³
This method can be foregone if none of the tested components exceed the permissible emission values or if the entire product is tested
4.1.2.2.
In the case of component testing, e. g. for furniture programs, the testing institute selects the components to be tested in consultation with the manufacturer. The different materials used, in particular different coating systems, must be taken into account. The selection must be made in such a way as to ensure compliance with the requirements of the award criteria for the product to be tested. In the case of components with a total area share of no more than 5% of the product, sample analyses and emission testing are not necessary.
The components to be tested are be taken directly from the current production in sufficient quantity. Supplied parts may not be older than 10 days. A deviation from this specification is
permissible if the manufacturer proves that individual supplied parts used in the normal production process are regularly older than 10 days. In the case of flat components, at least 3 parts must be taken as a stack, of which only the middle part is used for the emission test. The testing institute has to be consulted about the exact sample quantity, taking into account the size of the component and the emission test chamber to be used. The samples taken from the same components must be immediately packed together in airtight packing. The individual samples should be placed as close to each other as possible in order to minimise unavoidable emissions during transport to the testing institute.
The packaged sample material must be transported to the testing institute as quickly as possible. No more than 7 days may elapse between packaging and arrival at the testing institute.
4.1.3.
Until the start of the test, the test sample or sample material must be stored at the testing institute in packaged form.
When preparing the test samples for the emission test, only those flat components should be used that are stored on the inside of the stack and not those on the outside.
Components and complete products can be tested in their original condition in a large test chamber. In this case, possible low results for semi-volatile compounds must be taken into account. As a rule, test samples are to be taken from the sample material which can be examined in a test chamber suitable for volatile organic compounds. The test samples should represent the materials used and the different surfaces of a complete piece of furniture. Any narrow surfaces exposed by cutting must be sealed with a suitable sealant.
Self-adhesive, low-emission aluminium foil has proven suitable for this purpose. Any selfemission of the aluminium foil must be determined in preliminary tests.
When calculating the emission area, the surfaces on both sides and the narrow surfaces (without surfaces subsequently sealed as a result of test sample cuts) must be included.
After completion of the test samples, they must be immediately placed in the test chambers or stored in packages until the test chamber is loaded.
For the manufacturer's own internal documentation, a sampling protocol (dates of production, packaging, shipping, etc.) must be created for each sample.
The time between packaging of the samples at the manufacturer and loading of the chambers should be as short as possible. According to DIN EN 16516, the test must be started within 8 weeks after sampling, provided that the sample is stored in the laboratory in the specified
packaging and under normal indoor conditions. Sampling, sample receipt and test start must be documented in the test report

3) The substance Dimethylformamide (DMF, CAS 68-12-2) is treated separately during the assessment of CMR properties. For DMF, a limit value (based on the LCI value) of < 15 µg/m³ after 28 days applies. The value after 3 days shall not be included in the total evaluation. For the calculation of the R value, DMF must still be taken into account. This regulation is valid for a transitional period until 31.12.2023. As of 01.01.2024, it will no longer apply.
Formaldehyde and acetaldehyde are excluded from the CMR assessment (classification: Carc. 1B).
4) The R value is based on the current list of LCI values according to AgBB; https://www.umweltbundesamt.de/sites/default/files/medien/4031/dokumente/agbb_bewertungsschema_2021.pdf
Definitions of TVOCspec und TSVOC
TVOCspec:
Sum of all individual substances found ≥ 5 µg/m³ in the retention range C6–C16 (between nhexane up to and including n-hexadecane). The determination is carried out in accordance with the currently valid AgBB scheme. Data in the AgBB scheme for C substances apply here to CMR substances of category 1A and 1B.
TSVOC:
Sum of all individual substances ≥ 5 µg/m³ in the retention range > C16–C22. In individual cases, LCI values have been derived for SVOC. The SVOCs for which LCI values have been determined are to be included in the R value calculation for the requirements after 28 days and are no longer subject to the sum SVOC value. The sum of the TVOCspec value and the sum of the individual SVOC with LCI value must not exceed the TVOC requirements after 28 days (AgBB procedure).
General information on TVOC and TSVOC:
The basis for measuring the emission of volatile organic compounds and formaldehyde is the BAM test method in the current version. The requirements for the test chamber procedure and the analysis are based on DIN EN 16516 in conjunction with the DIN EN ISO 16000 et. seq. series of standards.
4.1.4.1. Odour
The odour test shall be performed after a minimum of 3 and a maximum of 28 days of residence time in the test chamber. In case of a previous test according to Point 4.1.4 testing can be carried out after the previous test is completed. In the case of several tests, the result of the last test series (longest period in test chamber) is definitive.
Requirements:
Score to be maintained: Level 3.0
The majority of individual scores must not be above level 3.0. The average must be ≤ 3.0.
Testing:
Odour neutral room:
Temperature: 23° C ± 1° C
Humidity 50% r. h. ± 5% r. h.
Airflow rate: Depending on the type of test sample
Chamber volume: The chamber volume is based on the specified test chamber size (Table 1)
Room loading: Depending on the type of test sample
At least 7 test persons independently assess the odour intensity according to a 5-point scale:
1 = no odour
2 = weak odour
3 = distinctive, not unpleasant odour
4 = unpleasant odour
5 = unbearable odour
The following should be recorded:
• Age and sex of test persons
• Room size
• Room temperature
• Room humidity (rel. humidity)
• Date of assessment
• Time span between production and odour assessment
• Type of odour
Test persons: The test persons (at least 7 persons, at least 3 of them women) should spend at least 10 minutes in a room with clean air before the odour test. The odour assessment is performed undiluted. The test persons should not have any previous exposure to the odours to be evaluated.
Mean value:
Of all the individual values determined, one highest and one lowest are not to be used for averaging. Only the mean value is given in test reports

Proof via manufacturer’s declaration possible.
4.2. Protection of environment and climate
4.2.1. Energy and eco-balance
The efforts of manufacturers to minimise the energy and atmospheric environmental impact associated with the transport of their products and supplier materials must be evident from appropriate documents.
The use of self-generated, renewable energy (e. g. burning waste wood) and the purchase of CO2 neutral energy are to be preferred.
To optimise the use of materials and energy with regard to a sustainable eco-balance, the implementation of a life cycle assessment based on the systematics of the standards DIN EN ISO 14001, DIN EN ISO 14040 and DIN EN ISO 14044 is suitable.
A life cycle assessment or environmental declaration of the products according to DIN EN ISO 14025 (EPD verification) is also recommended.
4.2.2. Human and ecosystem health
In addition to the legal regulations on the handling of chemicals that are harmful to humans and the environment (e. g. REACH Regulation), this Furniture Quality Assurance RAL-GZ 430 contains extensive testing requirements to ensure furniture that has been tested for harmful substances
4.2.2.1. Liquid coating systems
Operators of coating plants must comply with the requirements of the 31st Federal Imission Control Act (BlmSchV). This shall be proven via the manufacturer’s declaration
4.2.3. Use of materials
4.2.3.1. Solid wood and wood-based materials
Solid wood and wood-based materials must comply with EU Regulation 995/2010 and, as far as possible, originate from sustainably and legally managed forestry (FSC/PEFC documentation). When using waste wood in wood-based materials, the Waste Wood Ordinance must be observed. Proof of the pollutant limit values of the Waste Wood Ordinance according to testing in compliance with the EPF standard.
4.2.3.2. Plastic components
Plastic components > 50 g should be labelled according to DIN EN ISO 11469 and should not contain additives of other materials that conflict with recycling.
4.2.3.3. Adhesives
The VOC content of adhesives should not exceed 10% for water-based systems and 30% for solvent-based systems.
4.2.3.4. PVC
The use of PVC should be limited to furniture parts for which no equivalent other materials are available and for which the special properties of PVC are required.
The use of PVC must be indicated in the product information (PI). Dismountable PVC parts are exempt from this regulation if they are clearly marked as PVC parts
4.2.4. Circular economy
4.2.4.1.
The principles of recycling-friendly design (VDI 2243) must be observed. The use of recyclable and biodegradable materials is to be preferred.
For wear parts, a functional, compatible replacement is ensured over a period of at least 5 years.
The durability of the products shall be ensured by appropriate design.
4.2.4.2. Packaging
The packaging material must be suitable for reuse or recycling. The packaging must be designed in such a way that any volatile components of the furniture can outgas.
4.2.4.3. Reusability / recycling
With regard to reusability and recycling, no material preservatives (fungicides, insecticides, flame retardants) and no halogenated organic compounds may be added to the furniture, or the materials used for its production (wood-based materials, adhesives, coatings, etc.).
This excludes fungicides used solely for in-can preservation in water-based coatings and glues or flame retardants in which inorganic ammonium phosphates (diammonium phosphate, ammonium polyphosphate, etc.), boron compounds (boric acid, borates) or other waterreleasing minerals (aluminium trihydrate or similar) are used for flame retardation.
4.3. Social responsibility
With a view to sustainable human resources development and to ensure health, occupational safety and social working conditions, a company should, in accordance with good management practice, define and document responsibilities and procedural rules concerning this matter
• These include in particular:
• Fair hiring practices
• Continuing education of employees
• Social responsibility in company regulations
Social ethics may also include social measures for the local environment of the operating site (e. g. sponsoring cultural or charitable institutions).
Compliance with the requirements can be achieved through membership of the UN Global Compact 13.14 or equivalent certificates. The Deutsche Gütegemeinschaft Möbel supports the UN Global Compact and its 10 principles. These guiding principles for business and human rights are to be implemented by the quality mark users. The implementation is documented during the monitoring audits.
With regard to social responsibility for products of the supply chain over which the company has no direct influence, preference is to be given wherever possible to supplier companies that take social standards into account.
Advertising claims must not contain any statements such as “biologically tested” or similar statements that play down hazards as laid out in the EU Directive 67/548/EWG Article 23 (Designation) Section 4 (e. g. “non-toxic”, “no risk to health”, “free from ”).
It is a prerequisite for “furniture with the quality mark” that suitable materials and construction elements are used which are appropriate to the product and have been professionally processed. Safety, function, and utility are assessed according to the latest standards of technology at the time of product launch. Environmental and health protection as well as product information are essential quality features.
Deviations from the requirements laid out in the Quality and Testing Regulations may be made if an equivalent or higher quality and safety objective is achieved by other means. Suitable proof is required
Visual inspections are carried out under the following conditions (unless otherwise specified):
General assessment: At distance of 2 to 3 m
Detailed assessment: At distance of 0.7 ± 0.1 m
Assessment basis: normal vision; diffuse daylight (without direct sunlight or artificial light).
Parts that are not visible in the position of use or subordinate parts as well as irregularities that are only visible in grazing light are excluded from the assessment
The product information for office and contract furniture shall be made available to the retailer for marketing purposes and for passing on to the end customer and contains the following details based on RAL-GZ 430/8:
1. Product name
2. Product label*

The overall appearance of a piece of furniture is determined by the level of decorative design and the quality of workmanship. These criteria are examined and assessed as “technical quality features” according to objective aspects within the framework of furniture testing.
In contrast, the aesthetics of a piece of furniture depends greatly on the subjective perception of the observer or user. The aesthetics of a piece of furniture cannot be judged according to technical parameters. It is a question of individual taste, which is influenced by fashion trends, the environment, personal image needs, and art and taste sensations, among other things.

The implementation regulations of the Deutsche Gütegemeinschaft Möbel apply exclusively to the use of the quality mark.
11. Amendments
Amendments to these Quality and Testing Regulations require the prior written consent of RAL to become effective. They come into force after a reasonable period of time after they have been announced by the Executive Board.
12. Implementing Regulations for the Award and Use of the Quality Mark of the Deutsche Gütegemeinschaft Möbel e. V.
12.1. Assessment basis
The assessment basis for the quality mark consists of the Quality and Testing Regulations for Furniture. It is amended and further developed in line with technical progress.
12.2. Awarding the quality mark
11.2.1 The Deutsche Gütegemeinschaft Möbel e. V. awards the right to use the quality mark for furniture to manufacturers of quality furniture upon application.
11.2.2 The application for the award of the quality mark must be submitted in writing to the office of the Deutsche Gütegemeinschaft Möbel e. V., Friedrichstraße 13-15 in 90762 Fürth. The application must be accompanied by a list of the products which the applicant wishes to have approved for quality assurance as well as a legally binding signed certificate of commitment (Sample 1).
11.2.3 This application is reviewed by the Quality Committee. The Quality Association commissions a neutral testing institute to carry out the initial testing. The test result is sent in writing to the Quality Committee, the applicant, and the Executive Board of the Quality Association. In addition, the Quality Committee may arrange for a factory inspection to be carried out by authorised inspectors or inspectors authorised by the testing institute. The applicant shall bear the costs for this as well as the cost for the inspection of the products. The Quality Association may authorise the testing institute to request an advance payment for inspection costs.
11.2.4 If the result of the inspection is positive, the Executive Board of the Quality Association awards the quality mark to the applicant on the recommendation of the Quality Committee. The award is certified (Sample 2). If the result of the inspection is negative, the Quality Committee will defer the application. It must give reasons for the deferral in writing.
11.3.1 Users of the mark may only use the quality mark for products that comply with the Quality and Testing Regulations.
11.3.2 The Quality Association has the sole right to have marking materials of the quality mark produced for all purposes (embossing stamps, printing blocks, matrixes, seal stamps, rubber stamps, etc.) and to issue them or have them issued to the users of the quality mark or to grant permission for their production and to specify the type of application in more detail.
11.3.3 The Executive Board may issue special regulations for the use of the quality mark in advertising on brochures, offers, order confirmations and delivery bills, etc., in order to maintain fair competition and prevent misuse of the quality mark.
11.3.4 The right to use the quality mark ends in case of death, opening of insolvency proceedings, liquidation, withdrawal or if the user of the quality mark renounces the right to use the quality mark by legally signed declaration to the Managing Director by registered letter on a date determined by the user.
11.3.5 If the right to use the quality mark has been legally withdrawn, the award certificate and all means of labelling with the quality mark must be returned; there is no entitlement to reimbursement. The same applies if the right to use the quality mark has otherwise expired.
11.4.1 The Quality Association is entitled and obliged to monitor compliance with the Quality and Testing Regulations as well as the lawful and proper use of the quality mark.
11.4.2 Every user of the quality mark must take the necessary precautions to ensure that the products bearing the quality mark comply with the Quality and Testing Regulations. Careful records must be kept of the required internal quality control procedures. In addition, every user of the quality mark shall subject these products to the monitoring tests arranged by the Quality Association to the extent and frequency in accordance with the requirements of the Quality and Testing Regulations and shall bear the testing and transport costs incurred as a result.
11.4.3 The Quality Committee commissions neutral testing institutes (officially recognised material testing institutes or equivalent testing institutes) to carry out the monitoring tests and makes the necessary agreements with them.
11.4.4 Assessors authorised by the neutral testing institutes may carry out monitoring tests at the company of the quality mark user at any time without prior notification up to twice a year, inspect the records of the company's own inspections and visit the company during operating hours. Products requested by the assessor as test pieces are to be handed over immediately. The assessor is entitled to dismantle finished products during the inspection. If the test is carried out elsewhere, the test pieces must be clearly marked by the assessor immediately upon removal. Products of the quality mark user can also be taken from the trade.
11.4.5 The appointed testing institute determines the test results independently of the bodies of the Quality Association. The testing institute prepares a test report for each test, a copy of which is sent to the Quality Association and to the quality mark user in question. Further dissemination of the test result is prohibited.
11.4.6 In case of a negative test result or in case of complaints about products of the quality mark user, the Quality Committee has the test repeated.
11.4.7 In the case of inspections requested from the Quality Association by third parties, the inspection costs are borne by the complainant in the event of an unjustified complaint, and by the quality mark user in the event of a justified complaint.
11.5.1 If the Quality Committee identifies deficiencies in quality assurance, it proposes sanctioning measures to the Executive Board of the Quality Association. Depending on the severity of the violation, the Board may:
11.5.1.1 Issue an instruction and/or a warning against the user of the quality mark,
11.5.1.2 Order an increase in the number of monitoring tests to be carried out for a certain period of time,
11.5.1.3 Impose the payment of a contractual penalty depending on the extent of the breach in question, up to EUR 10,000 in favour of the Quality Association,
11.5.1.4 Withdraw the right to use the quality mark temporarily or permanently.
11.5.2 If deviations from the Quality and Testing Regulations or an infringement of the conditions of use of the quality mark are detected during inspection of the products of the quality mark user, an instruction or warning will be issued. Depending on circumstances, the latter is issued in conjunction with an ordered increase in the number of monitoring tests to be carried out and/or by the imposition of a contractual penalty. The contractual penalty is to be paid to Deutsche Gütegemeinschaft Möbel e. V. within 14 days after the decision has become legally binding.
11.5.3 The right to use the quality mark will be withdrawn temporarily or permanently if the Quality and Testing Regulations or the conditions for use of the quality mark have been repeatedly violated, or if the quality mark has been misused, or if a deliberate violation of the Quality and Testing Regulations has been proven, or if the quality mark user otherwise grossly violates the quality assurance through their conduct.
11.5.4 Should a member use the quality mark without authorisation or allow a third party to affix it to their products or permit the third party to use the quality mark in any other way, a contractual penalty of up to EUR 10,000 will be due for each individual case. Any legal action ensuing from such behaviour will not be affected by the issuing of said penalties.
11.5.5 A penalty as laid out under Section 5.1 may also be issued if the quality mark user delays or obstructs immediate monitoring tests as described under Section 4.
11.5.6 The affected party must be heard before any measures are taken. Before the right to use the quality mark is withdrawn from a quality mark user, the affected party must be given the opportunity to make a statement within a period of 4 weeks.
11.5.7 In urgent cases, the Chairman of the Quality Association may provisionally prohibit a quality mark user from using the quality mark with immediate effect. Such an order must be confirmed or rescinded by the Executive Board of the Quality Association within 14 days.
11.5.8 The duty of the Quality Association to intervene against impairment of the use of the quality mark and in the event of misuse of the quality mark also obliges the users of the quality mark under trademark law to notify the Managing Director of the Quality Association without delay of any violations of the conditions of use of the quality mark and any cases of misuse of the quality mark of which they become aware and to submit substantiating documents so that the violation can be prosecuted in an appropriate manner. Failure to do so shall be punished in accordance with Section 5.1.
11.5.9 Measures taken by the Quality Association to protect the quality mark within the meaning of these provisions shall not affect the right of quality mark users to assert
any claims for compensation for damage directly incurred by them as a result of infringement under civil law.
12.6. Objection
11.6.1 The quality mark user may lodge an appeal with the Quality Committee against a penalty notice in accordance with Section 5.1 within 4 weeks of notification of the notice. A decision on the appeal must be made within 4 weeks. The appeal has a suspensive effect; however, in the event of an acute risk of misleading the market, the Quality Committee may provisionally confirm a sanctioning measure in accordance with Section 5.1.4 even before deciding on the appeal.
11.6.2 If the objection is rejected, the complainant may take legal action in accordance with Section 11 of the Articles of Association within 4 weeks of being served with the decision rejecting the complaint.
12.7. Reinstatement of usage rights
If the right to use the quality mark has been withdrawn, it may be re-awarded after three months at the earliest. The procedure is determined in accordance with Section 2. However, the Executive Board of the Quality Association may impose additional conditions.

The furniture buyer is obligated to point out construction- related conditions and obstacles! If obstacles are not indicated in the purchase contract, the assembler has the duty of care to check the following details before assembly, which inhibit , restrict, or possibly exclude correct assembly.
The basis for the test is an electronic construction and cable finder for:
• Electrical lines
• Water/drainpipes
• Heating pipes – wall and floor heating
• Communication/TV connections
• Gas connections
When connecting extractor hoods, open fireplaces must be taken into account. An additional circuit with a tilt switch to the window is necessary here to ensure a sufficient amount of air in the room.
Installation may only be carried out by qualified personnel.

Requirements for different product groups
General classification of devices and modules according to the Low Voltage Directive or the Machinery Directive
Abbreviations and their meaning
Installation in furniture
General remarks
Aim:
This guideline provides an overview of the essential standards and technical rules to be taken into consideration where statutory regulations on product safety and product labelling in the European Economic Area are concerned.
General instructions for purchasing:
1. The supplier must submit precise product-specific test certificates on product safety in accordance with the relevant EU directives. Declarations of conformity alone or only the cover page of certificates are not sufficient for manufacturer liability. It must be ensured that the test reports or test certificates are up to date.
2. A release from liability with the pre-supplier must be contractually stipulated
3. The system requirements for the respective area of application must already be contractually specified when the order is placed.
4. The requirements for the individual destination countries with regard to labelling and normative requirements are to be listed and requested with the order.
Note on the specification of standards:
If no date of issue is given for standards or guidelines, the current version applies. Special attention must be paid to any transitional periods.
The Low Voltage Directive is to be considered only for certain nominal voltages of a device:
For DC voltage: 75 to 1500 Volt
For AC voltage: 50 to 1000 Volt
For electrified furniture that has a connection to the main network, the Low Voltage Directive applies in all cases.
Disclaimer: These guidelines are intended as a guide and make no claim to completeness. In individual cases, it is also necessary to check which requirements must be met in accordance with the relevant legal regulations. No liability can be assumed for individual cases.
Labelling according to the Product Safety Act (ProdSG of 8 November 2011)
Consumer products must generally be labelled according to Section 6 of the Product Safety Act with:
- Name and contact address of the manufacturer
- Clear labelling for identification of the consumer product
If the manufacturer is based outside the European Economic Area, some obligations are transferred to the importer. For example, the importer must ensure that a European address is provided and that the technical documentation for the product is available or prepared.
If products are manufactured outside the EU but sold under the name of a European ( trading) company (OEM business), then the European company becomes a quasi-manufacturer and must fulfil all the obligations of a manufacturer (including the issuance of the declaration of conformity).
Liability risks: Incorrect and misleading labelling of products may give rise to regulatory or competition law liability risks. In the event of a hazard, regulatory authorities may order product recalls. Likewise, in the event of liability, insurance law problems may arise in the event of gross negligence, which may even lead to the loss of insurance coverage.
A product must bear the CE label if the product falls within the scope of at least one EC Directive that requires this label.
The “CE Directives” are usually all equally valid. If a product falls within the scope of several directives, then all of them must be observed (e. g. Low Voltage Directive and EMC Directive). In the declaration of conformity, several directives must be mentioned accordingly (or several declarations of conformity must be issued).
Exceptions:
If a product falls within the scope of the Machinery Directive and the Low Voltage Directive, then formally only the Machinery Directive applies to the declaration of conformity. However, the technical safety requirements of the Low Voltage Directive, which is mentioned as a cross-reference in the Machinery Directive, must be fulfilled.
If a product falls within the scope of the RED Directive, then the EMC Directive and the Low Voltage Directive formally fall away in the declaration of conformity. However, the RED Directive itself contains cross-references to the technical requirements of the EMC Directive and the Low Voltage Directive.
In the case of furniture that falls under the Electrical and Electronic Equipment Act (ElektroG), appropriate labelling must be applied to the furniture and the method of disposal must be indicated in the operating instructions.
In the case of declarations of conformity in accordance with EC Directives based on internal manufacturing controls, special technical instruction may be required for employees in manufacturing who install electrical components or manufacture machines.
The existing conformity assessment documents (and thus also the declaration of conformity and the CE labelling) always apply only to the product in the condition in which the assessment was made.
If a product is substantially changed, e. g. by a processing company, then the person who makes these changes becomes the manufacturer of a new product and must carry out a new conformity assessment (including declaration of conformity and labelling).
Such changes may include operative changes to the product itself, but also changes to the environmental conditions intended by the original manufacturer:
Example: Installation of a device actually intended for desktop operation in a closed housing (=> problems with heat dissipation). Commercially available AV/IT devices, for example, are usually not designed for complete integration, but for free-standing installation with sufficient air space for cooling around the device
When combining components into a final product (e. g. wiring of multiple ballasts, connecting cables and lamps), it CANNOT be assumed that the complete product automatically meets the requirements of all directives if the individual components are CE marked individually:
- In some cases, the combination results in new requirements.
- The combination may cause limit values to be exceeded that are still met individually

(Other directives are not considered in this note but may apply beyond it.)
Electromechanical drives for furniture must first be assigned to the Low Voltage Directive. Within the framework of the conformity assessment procedure according to the Machinery Directive2), the drives are to be differentiated, on the one hand, according to the “intended use” defined by the manufacturer and, on the other hand, according to the comprehensiveness of the delivery condition (“Does it fulfil the intended function without further ado or not?”).
The dependent accessories required for the drive, e. g. power supply units, controls, etc., which are purchased in direct connection with the drive and do not contain any moving components of their own, are also subject to the Low Voltage Directive.
Further documentation can be agreed between the customer and the manufacturer. All cited standards must correspond to the valid dates of the EU Official Journals if they may be used for conformity assessment.

Upholstered furniture is soft and formable. To maintain the furniture’s usage properties and quality, maintenance care is indispensable.
The following measures should therefore be carried out regularly to maintain the furniture’s value:
Regular use will leave traces on the upholstery, such as seat imprints, shifted seams and rippling on the used surfaces. By fluffing up the cushions/upholstery, upholstered furniture quickly regains its desired shape and appearance.
Hold the back cushion firmly with one hand in the back and fluff the cushion using the other hand. .
Fluff the back cushion with both hands at the same time, thereby distributing the filling evenly.
Subsequent to the back cushion, fluff the armrest cushions in the same way.
Maintenance care is particularly important for furniture with this type of upholstery (quilted mats, loose filling material, functions, etc.). This furniture already has a certain wavy appearance at the time of delivery. In most cases, high-quality chamber cushions are incorporated in the seat and/or back. The filling material is held in chambers within the cushions so that it does not shift. Depending on the type and thickness of the cover material,
both the chambers and the filling material will sometimes show more and sometimes less. By fluffing up the cushion after use, the compression of the cushion filling can be largely reversed.
These depend on use and are unavoidable. By gently pulling and aligning the cover, any seam offsets and/or height differences can be adjusted.
General information
Functional elements:
Always return the functional elements (footrests, headrests, etc.) to their original position after use so that no compression in the foam or visible marks form on the cover.
When using one of the functional elements, metal abrasion may occur, which should be removed regularly by wiping or vacuuming (depending on the floor covering).
Construction elements:
Mounted feet that can become loose during use should be aligned and tightened occasionally. Wear parts such as felt gliders should be replaced in time before they wear out.
cleaning
Fabric covers:
Regular brushing with a soft natural brush prolongs the life of the covers. Careful vacuuming with a vacuum cleaner is also recommended.
Leather covers:
Leather covers should be dusted once a week. Then wipe large areas with a damp cloth (Note: use only distilled or boiled water and do not use microfibre cloths or sponges).
Wood:
Varnished and waxed surfaces should be cleaned and maintained with a slightly damp leather cloth. The surfaces must be protected from hot objects.
Metal:
Metal surfaces should be cleaned and cared for with a damp cloth and detergent. Then polish with a dry, soft cloth.
Special cleaning agents are commercially available for polished surfaces.
General rule:
Liquids should always be removed immediately by dabbing.
Solvents and scouring agents should not be used.
Specific instructions from the manufacturer, e. g. cleaning and care instructions, must always be followed as a matter of priority.
13.7. Assessment of ripple formation on seating surfaces
A ripple is a deformation that deviates from the original cushion surface. A fold is a ripple with a crease.
Casual upholstered seating surfaces have a tendency to ripple in use. Ripples occur because of the main tensioning direction of the upholstery – from front to back – transverse to the tensioning direction. Such ripples are typical for casual upholstery.
Further causes for the formation of ripples in covers can be material stretching of the covers, punctual loads, too large cuts, weakening upholstery materials. etc.
Ripples in seating surfaces are permissible if the largest ripple, related to a seat width of 700 mm, is max. 20 mm high. The seat width is to be measured from seam to seam. If the seat width is interrupted by dividing seams, these are not to be taken into account for the evaluation of the seat width for the measurement. The following table serves as a guideline for the assessment of ripples on the seating surface of an upholstered piece of furniture. The ripple measurement is carried out by means of a ripple measuring device (aid), which is placed over the ripple created after the cover has been folded.
At the beginning of the test, the cover is to be smoothed and a seat test is to be carried out. After standing up, without pulling the side edges inwards, the cover is smoothed together from both sides towards the middle of the seat width. The height of the resulting largest ripple is measured.
The measuring device must not be pressed into the upholstery.
This procedure must not be followed for particularly casual models where the cover cut has been kept somewhat larger for design reasons or where the upholstery construction has been made with softer materials (e. g. down covers, especially fine padding, mat covers, belt underspringing, etc.). In this case, the ripple formation can be more pronounced without a justified complaint.
The testing and assessment method is to be applied equally to furniture leather and furniture fabrics.
Ripple / fold formation
Readout line
Execution
Before the test, the cover shall be smoothed, and a seat test performed.
After standing up, without pulling the side edges inwards, the cover is smoothed together from both sides towards the centre of the seat width. The height of the resulting largest ripple is measured. The measuring device must not be pressed into the upholstery.
Assessment
Ripples are permissible if the largest ripple, related to a seat width of 700 mm, is max. 20 mm high. In case of deviating seat widths (700 mm), the values must be converted accordingly. For corner elements, the seat surface is measured at the point with the largest seat width. This test method is to be used for both furniture leather and furniture fabrics equally.

Measurements are taken from seam to seam, including any curvature of the upholstery.
If the seat width is interrupted by a dividing seam, this should not be taken into account when evaluating the seat width for measurement (see picture above).
Division of the upholstery areas – E = element
L1 = seat width element E1
L2 = seat width element E2
L3 = largest seat width element E3
L4 = different seat width with diving seam E4
13.7.1. Upholstered furniture – Table for permissible ripple formation
Depending on the seat width according to RAL-GZ 430
This table serves as a guideline for the assessment of ripples on the seating surface of upholstery furniture (not for backrests). The calculation is based on a seat width of 700 mm. Here, a ripple height of no more than 20 mm may occur after the cover has been smoothed together towards the centre. The ripple measurement is carried out by means of a ripple measuring device (aid), which is placed above the ripple created after the cover has been folded.
Exception: This procedure must not be followed for particularly casual models where the cover cut has been kept slightly larger for design reasons or where the upholstery construction has been made with softer materials (e. g. down covers, especially fine padding, mat covers, belt under-springing, etc.). These guide values cannot be applied here. In this case, the ripple formation can be more pronounced without a justified complaint.
13.8. Odour test for furniture leather
Quick method based on VDA 270 and RAL-GZ 430
Aim: The simplified odour test is intended as an incoming goods inspection for furniture manufacturers and as an orienting test in the event of odour complaints from customers.
Test procedure: The test is carried out in accordance with VDA 270 with the following changes and concretisations:
a) Test equipment and chemicals:

PUR standard foam
Foam of types MB and MM according to EN ISO 5999 with a rebound resilience, measured according to ISO 8307, of greater than 15% and less than 50%. The molecular weight of conventional PUR foams is between 3,000 and 3,500 Dalton.
Note: Another characteristic of PUR standard foam, in contrast to HR foam, is the crystalline urea that predominantly forms during production. Due to the different morphology of PUR standard foam compared to PUR cold foam, it can be clearly identified using IR spectroscopy.
PUR polyurethane foam according to EN ISO 5999 of the types MB, HB and HM, produced with highly reactive polyols and a closed-cell pore structure, which is broken up after production by crushing for better air permeability and has a rebound resilience of more than 50%, measured according to DIN ISO 8307. The molecular weight of PUR cold foams is between 5,000 and 6,000 Dalton.
Note: Further characteristics of PUR cold foam, also known as HR foam (HR = High Resilient), is a SAG factor according to EN ISO 2439 of at least 2.5 and the amorphous or dissolved carbonic acid diamide (urea) that is formed exclusively during production.
Foam of types LB and LM according to EN ISO 5999 with predominantly viscous behaviour, in which the rebound resilience measured according to DIN ISO 8307 is at most 15%.
Note: Two types of viscous foam are distinguished. Pneumatic viscous foam with predominantly closed or microporous cells and chemical viscous foam with open cells. In terms of the dependence of its mechanical properties on temperature, pneumatic foam is less sensitive than chemical viscous foam.
PUR hypersoft foam is an extremely soft, elastic, supple and air-permeable PUR foam for nonload-bearing purposes as defined in DIN EN ISO 5999 with compressive stress values below 2.0 kPA or indentation hardness below 80 N, in which carbon dioxide is added during production or a special polyol is used and in which the chain ends produced by polyaddition contain almost exclusively primary OH groups.
Note: PUR hypersoft foam is suitable for the production of mattress toppers and cushions as well as for upholstered furniture as a cover layer between the load-bearing foam and the cover fabric.
Gel foam is a relatively new PUR soft foam of a rather viscous character, which is produced with organic or synthetic gel particles or binds them.
The rebound resilience is approx. 15% according to DIN EN ISO 8307, resulting in an assignment to the group of viscous soft foams according to DIN EN ISO 5999. The other technical characteristics according to DIN EN ISO 5999 (Flexible elastic polymer foamsPolyurethane foams for upholstery purposes with the exception of carpet underlays) vary, which makes a clear classification according to DIN EN ISO 5999 difficult.
Note: Further specification is currently being discussed among experts. A number of inaccurate statements are made about gel foam in the trade – further specification in the definition is therefore necessary.
13.11. Explanation of the term “force majeure”
Definition Deutsche Gütegemeinschaft Möbel e. V.
(Member of RAL German Institute for Quality Assurance and Labelling e. V.)
1. Definition
In general, the term "force majeure" is understood to mean an event that comes from outside, has no operational connection and cannot be averted even by the utmost diligence that could reasonably be expected (instead of many: BGHZ 100, 185). Events such as natural disasters (hurricanes, earthquakes, or floods), (local) epidemics, pandemics, wars, and political unrest are usually regarded as "force majeure". Official measures and warnings are also a strong indication of the existence of force majeure. 1
The supplier and the customer agree that the following circumstances are also to be attributed to force majeure:
o Transport and freight delays for which the supplier is not responsible (in particular in the event of delayed receipt despite timely handover of the goods from the Supplier to the transport person)
o Operational disruptions for which the supplier is not responsible or pandemic capacity reductions of any kind due to a lack of manpower, energy, preliminary products, raw materials and untimely or improper own preliminary supply of the supplier (interruption of the supply chains), which significantly change the economic significance or the content of the delivery or have a significant effect on the supplier's operations
o Damage at the supplier or his sub-suppliers caused by natural disaster
o Strikes or labour disputes including lawful lockouts
o Attacks on the supplier's IT system which are detrimental to the production process
o Delays for which the supplier is not responsible due to difficulties in obtaining the necessary official approvals
o In case of border closure or official measure, instruction, or warning
2. Legal consequences due to force majeure as defined under Item 1
A contracting party who is unable to deliver in accordance with the contract due to force majeure shall be obliged to inform the contractual partner immediately of the reason and the expected duration of the delay in delivery. At the request of the contractual partner, the supplier shall be obliged to explain the objective existence of the force majeure and the effects on the ability to deliver.
Contractual delivery periods shall be automatically extended by the duration of the hindrance due to force majeure. Other reasons for delay may not be taken into account. Claims for damages, contractual penalties, or termination/withdrawal from the contract due to the delay in delivery on account of force majeure may not be asserted.
In the event of delays in delivery due to force majeure, the contract shall be adjusted appropriately at the request of either party in good faith. Insofar as this is not economically justifiable from the supplier's point of view, the supplier shall have the right to withdraw from the contract.
Fürth, November 2021
1 Case law
Case law has ruled that the term “force majeure” within the meaning of travel law may include war, a terrorist attack, massive violent unrest (LG Frankfurt a. M. RRa 2015, 8; also BT-Drs. 8/2343, p. 12), a reactor accident (BGHZ 109, 224) or the outbreak of an epidemic such as SARS (AG Augsburg 14 C 4608/03).
13.12. Emission class for furniture according to RAL-RG 437
For the members of the DGM, healthy living has been a focus for many years. There has been great progress due to environmental protection and building refurbishment over the last few decades. Our homes have become increasingly tight due to thermal insulation systems and windows that seal properly. Natural air exchange is only possible through thorough ventilation or automatic ventilation systems, such as in low-energy houses or public buildings.
Pollutants can be emitted from a wide range of different products, such as building materials, adhesives, wallpaper, varnishes, furnishing materials or furniture. Therefore, all materials used indoors must be low in harmful substances and release as few emissions as possible into the ambient air.
In cooperation with leading testing institutes such as TÜV Rheinland and eco-INSTITUT, a group of DGM experts has developed emission classes for furniture. The objective was to develop a label that provides the consumer with the most important information on the emission profile in a simple way. This seems to be useful for a risk assessment in our opinion since the legislator does not specify limit values for many pollutants. Emission class A signifies a low risk of exposure to pollutants.
The emission label can be awarded to the following collections/models:
Seating furniture
Cabinet furniture
Tables
Office furniture
Slatted frames
Mattresses
Beds
The basic principles are stipulated in the RAL registration RAL-RG 437 Emission classes for furniture.
An emission label provides the consumer with information on pollutant emissions and is intended to protect the consumer from detrimental health effects. The emission label developed by the Deutsche Gütegemeinschaft Möbel e. V. refers to a collection / a model and is attached directly to the product/s. Proof of classification is based on appropriate pollutant tests, and the label is awarded exclusively by the Deutsche Gütegemeinschaft Möbel e. V.
13.13. Climate neutral furniture manufacturer for the furniture industry according RALGZ 435
To mark their sense of responsibility towards climate change, furniture manufacturers can have themselves certified with regard to the Climate Pact. This provides consumers with an additional basis for decision-making, as it shows them that they are dealing with a piece of furniture whose manufacturer attaches importance to climate protection. In the further development of the climate pact, there is the possibility of being specially distinguished as a climate neutral furniture manufacturer. The award is made exclusively by the Deutsche Gütegemeinschaft Möbel e. V.
The foundation of the Climate Pact is a company's carbon footprint. Furniture manufacturers who join the pact have their “footprint” calculated annually by a neutral body on the basis of applicable standards. This footprint is made up of direct and indirect greenhouse gas emissions.
Scope 1: Direct emissions of the company resulting from the consumption of primary energy sources
= Burning of fossil raw materials for energy production, heat generation, fuels for company-owned cars and trucks, process emissions, and refilling of cooling and air-conditioning systems.
Scope 2: Indirect emissions resulting from the generation of self-procured energy = Secondary energy sources such as electricity, district heating, steam, or cooling energy.
Scope 3: All indirect emissions resulting from the operation of all daily business processes and the product life cycle
= Mining and processing of raw materials, consumables and supplies, upstream chains of fuels, thermal energy, process energy and electricity production, employee travel, external logistics, business flights, business travel incl. overnight stays, commercial waste, paper and cardboard consumption, water consumption.
