RCM certification
RCM (Regulatory Compliance Mark) is a registered mark indicating that the supplier declares that the product complies with the safety and other requirements stipulated in the electrical safety laws/regulations of Australian states and New Zealand, and also complies with the Australian Radio Communications Act and the New Zealand Radio Communications Act "Electromagnetic compatibility requirements specified in Only products that meet the requirements of both electrical safety regulations and EMC regulations can use the RCM mark. This mark is a trademark owned by regulatory agencies in Australia and New Zealand, indicating that the product meets both safety and EMC requirements and is non-mandatory.
Figure 11 RCM certification
RCM certification requirements
1 ► SAA certification and C-Tick certification will be gradually canceled and replaced by RCM certification, which covers safety and EMC (C-TIck may still be applicable to some low-power wireless products).
2 ► All electronic products will be divided into three categories: High, Medium and Low Risk. Generally speaking, battery-driven products and products with a voltage below 12V are low-risk, 240V standard voltage products are medium-risk, and high-voltage products are high-risk. The buffer period for low-risk products is 6 months, and the buffer period for medium- and high-risk products is 3 years (this period is recommended by the relevant Australian associations, but the government has not yet finalized the specific decree).
3 ► RCM certification can only be applied for by local Australian companies, and the company must apply for an RCM number from the Australian government. Chinese manufacturers and exporters can apply for IEC or AS/NZS reports in their own names, but the reports must be submitted to Australian importers to apply for RCM.
4 ► According to expert opinions, since the importer will bear the risk of substandard product quality (responsible party), and non-Australian companies cannot directly apply for RCM certification. It is estimated that more and more sizable Australian companies will change the practice of having Chinese manufacturers bear the cost of producing reports and applying for SAA in order to reduce costs. They will tend to designate laboratories with certain capabilities and reputation, provide insurance reports and test data, and then let them apply for Australian RCM certification.
5 ► In theory, Australian laboratories can also serve as applicants to help a company obtain RCM certification. However, according to expert opinions, due to the greater legal liability, it is estimated that most Australian laboratories will not take the initiative to take this risk. Even if they do, the related costs may be relatively high.
RCM certification application process
1 ► A third-party laboratory evaluates the product and determines the testing standards to be implemented;
2 ► If there are any non-conformities in the test, the laboratory will rectify the product to comply with and meet the requirements of Australian standards;
3 ► After the test passes, a test report is issued;
4 ► Submit the test report to the Australian certification authority for document review;
5 ► Australia passed the review and issued the RCM certificate;
6 ► Customers can complete the Australian website registration by themselves or by the laboratory.
