Foreword to the Furniture Quality Assurance RAL-GZ 430
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 Standardisation
It 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. recognized 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.
Dr Susanne Steinhauer Chairwoman Advisory Board for Sustainability


1. Area of Application
These Quality and Testing Regulations apply to the condition of kitchen and bathroom furniture 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 68930 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.
2. Quality and Testing Regulations
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.
3. Monitoring Monitoring is divided as follows:
• Initial testing
• Internal quality control
• External quality control
• Repeat testing
• Testing and monitoring reports / Approval license
• Testing costs
• Inspectors
3.1. Initial testing
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. Internal quality control
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. External quality control
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 furniture”.
3.4. Repeat testing of external quality control
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 11.5 Implementing Regulations for the Award and Use of the Quality Mark.
3.5. Test and monitoring report / Approval license
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. Testing costs
The applicant or quality mark user must bear all arising testing or monitoring costs.
3.7. Inspectors
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.
4. Sustainability
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 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, in particular in the object area, are not taken into consideration.
Initial and monitoring tests are to be carried out according to Point 3.
4.1. Protection of health
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. Requirements for test samples
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. Test material
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.
4.1.2.1. Whole-body testing
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.
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

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. Component testing
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.
4.1.2.3. Transport

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. Sample preparation
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.
4.1.4. Emission requirements for kitchen and bathroom furniture
Table 1 – Emission requirements for kitchen and bathroom furniture
1) The test can be terminated on the 7th day after loading if the required final values of the 28th day are reached and no increase in concentration of one of the detected substances can be detected compared to the measurement on the 3rd day.
2) Sum of all individual substances ≥ 5 µg/m³) at test chamber concentration
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 and 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 und 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

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.

4.1.5. Additional material requirements
4.1.5.1. Chlorophenols
Pentachlorphenols / Tetrachlorphenols / Trichlorphenols

Proof via manufacturer’s declaration possible.

4.2. Protection of the 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. Constructional layout – wear – durability
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

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 (see Annex 12.9) 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
4.4. Advertising statements
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 ”).
5. General Quality Principles
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 Quality and Testing Regulations
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
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.

6.5. Movable parts
Preliminary remark:
In the course of the development of international test standards and from the experience gained by the DGM in the past years, fittings and components for domestic furniture are tested under defined laboratory conditions. The suitability for use is assessed on the basis of the test results. Extensive practical experience in connection with living room furniture was taken into account to define relevant requirements and test methods.


However, given the variety of different concepts of home furniture, the designer is required to test these assumed requirements to determine the extent to which the individual furniture element meets these assumptions (load/test method). If this is not the case, fittings and/or components must be selected in cooperation with the fittings manufacturer so that the finished furniture complies with the loads to be expected in practice according to RAL-GZ 430.
Note: A possible temperature influence on the function of damping elements is not taken into account in the following tests.
6.5.1. Hinged doors / concealed hinges (also all-glass doors)

6.5.6.2. Safety (second lid)
Requirements:
• Safety according to DIN EN 14749
Testing according to DIN EN 14749 (second lid)
6.5.7. Carousel hinges with shelves or storage units
Functionality and safety tests are carried out separately and in the following order on two cabinets, their associated shelves and/or other accessories.
If the durability of the test object permits, the safety test can be performed on the same test object following the functionality test.
The possibility of readjusting the functional values must be taken into account when evaluating the test results.
6.5.7.1. Functionality (first cabinet)
Requirements before and after the test:
• Full functionality
• Movement force for rotary movement with functionally correct actuation: max. 25 N, except for locking and damping areas

• Opening and closing force: max. 50 N
• Lowering < 4% of the shelf bottom radius
• Lowering of fronts < 2 mm
In the case of carousel hinges, whose metal hinges have been tested according to this DGM testing regulation and received a test certificate, are usually only submitted to a safety test. The prerequisite is that the dimensions and weights do not exceed the specifications according to the test certificate by more than 20%. In justified cases, a functionality test is also carried out.
At the beginning of the tests, all surfaces or volumes intended for loading are loaded evenly with 0.25 kg/dm3, max. stacking height 250 mm, but not more than 25 kg/floor or, as specified by the manufacturer, with fixed 1 kg steel plates in accordance with DIN EN 16122, except for the impact tests (glass balls).

All furniture components not subjected to direct testing must be loaded in accordance with Table 1 in DIN EN 14749.
6.5.7.1.1. Vertical loading of front panels before the durability test
Test:
Test parameters: 120 N
Test force: At a distance of 50 mm from the most unstable upper front corner vertically downwards

Force application point: Front panel closed or fully open*
Number of cycles: 10
Frequency: 5 cycles/min
*If loads cannot be applied to the front panel from above, then they should be applied to the handle if this permits the application of force.
6.5.7.1.2. Vertical loading of shelf bottoms before the durability test
Test:
Test parameters: 1.25 N/dm3 x floor area x stacking height (max. 250 mm) but not more than 200 N vertically downwards
Force application point: The two shelf bottom points with the lowest strength and the greatest distance. Shelf bottom unloaded. Force application 50 mm from the edge
Number of cycles: 2500 times alternately per point
Frequency: 10 load changes/minute
6.5.7.1.3. Durability test
Test:
Number of cycles: 2 x 20,000

Frequency: 2 to 8/min.
Before the wear test, all shelf bottoms are unloaded and adjusted to the basic position. The positions of all assemblies determined in this way are used after the durability test to determine the lowering of the front and bottoms.
The loaded carousel hinges are moved to the right (20,000) and left (20,000) starting from the closed position and rotated fully if this is possible. The direction of rotation is changed every 5,000 rotations. Shelves that allow only one-sided rotation are tested in one direction. Semicircular shelves are tested rotating up to 10° in front of the end stops. Integrated functional elements such as springs, dampers, etc. are to be subjected to practical stress.

6.5.7.1.4. Vertical loading of shelf bottoms after the durability test
Test:
Test parameters: 1.25 N/dm3 x floor area x stacking height (max. 250 mm) but not more than 200 N vertically downwards
Force application point: The two shelf bottom points with the lowest strength and the greatest distance. Shelf bottom unloaded. Force application 50 mm from edge.
Number of cycles: 2500 times alternately per point

Frequency: 10 load changes/minute
6.5.7.1.5. Dynamic loading of the stops
Stops limiting rotational or sliding movements shall be tested for durability.
Rotation beyond the stops is permissible.
Test:
Load: 0.25 kg/dm3 stacking height max. 250 mm max. 25 kg/shelf
Test parameters: W + Fg (2 kg)
Number of cycles: 10 times in each direction
Frequency: 2/min.
Instead of steel plates, all rotating shelves are loaded with 1 kg bags filled with glass balls (10 to 15 mm diameter). The border can be adjusted in height so that the bags do not slip over the edge
The rotating or sliding operating assembly is to be opened or closed using a cord or string (sheathed steel cable ø 1.5 mm is also suitable) attached near the handle Due to the design, it may be necessary to attach the cord directly to the shelf.
The weight (W) required to move the door straight is determined.
The assembly is closed 10 times using the test weight (W + Fg). The start of the movement is the 45° open position for rotary actuation. The test force shall be removed 10 mm before the position where the stop becomes effective. Sliding components are to be tested with W+2 kg following sliding doors according to DIN EN 14749.
6.5.7.2. Safety (second cabinet)
Requirements:
• Safety according to DIN EN 14749
Testing according to DIN EN 14749 (second cabinet)
