Navigating the diverse classifications and levels within Australian RCM Compliance for electronic products can be perplexing, particularly for those embarking on their careers in product testing and compliance. Here, we demystify these standards and regulations, providing clarity and ease of understanding for readers at the onset of their professional journey.


EMC Classes: (Class A & Class B)

Electrical Safety Classes (Class I, Class II & Class III)

In Scope Electrical Equipment Levels (Level 1, Level 2 & Level 3) in Australia

ACMA Compliance Levels (Level 1, Level 2, Level 3)



EMC Classes: (Class A & 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 use in 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 minimize their impact on other electronic systems operating in its close vicinity. Class B compliant devices can be used in class A environment.
