THE FUNDAMENTALS OF AUSTRALIAN RCM COMPLIANCE DIFFERENT TYPES OF CLASSES AND LEVELS
Generally, standards and regulations have their own classifications and levels for electronic products.
I
t can be confusing to some readers, especially someone in the initial phase of their career in product testing and compliance. Here, Nisha Lad, Compliance Project Manager at C-PRAV Labs & Certifications, explains the differences in classes and levels in RCM compliance.

EMC classes: (Class A and Class B) as defined in most EMC Standards In the context of EMC (electromagnetic compatibility), Class A and Class B refer to two different levels of electromagnetic emissions limits for electronic devices. Class A: Devices that comply with Class A standards are typically intended for use in industrial environments, where there are fewer restrictions on electromagnetic interference. Class A devices are expected to have higher emission levels of electromagnetic emissions compared to Class B
devices. Class A compliant devices are not meant to be used in a Class B environment. Class B: Devices that comply with Class B standards are intended for use in residential, commercial and business environments, where there are stricter regulations on electromagnetic interference. Class B devices are required to have a higher level of electromagnetic interference suppression compared to Class A devices to minimise their impact on other electronic systems operating in their close vicinity. Class B compliant devices can be used in a Class A environment.
