The International Electrotechnical Commission (IECEE) has released a new version of the CB certificate rules operating document OD-2037, version 4.3, through its official website, which came into effect on January 1, 2024.
The new version of the document has added requirements for CB certificate rules in terms of functional safety expression, multiple product standards, model naming, separate software package certification, battery standards, etc
1. The CB certificate has added relevant descriptions of functional safety, and the rated value and main characteristics should include electrical characteristics, safety level (SIL, PL), and safety functions as much as possible. Additional safety parameters (such as PFH, MTTFd) can be added to some additional information. To clearly identify the testing items, the functional safety report information can be added as a reference in the additional information column.
2. When providing all relevant test reports as attachments to the CB certificate, it is allowed to issue a CB certificate for products that cover multiple categories and standards (such as power supplies).
From a hardware and software perspective, different product configurations must have a unique model name.
4. Provide independent software packages for product security measures (such as software libraries, software for programmable ICs, and specialized integrated circuits). If designated for final product applications, the certificate should state that the software package needs to undergo additional evaluation based on the final product requirements to ensure compliance with relevant standards.
If the IEC Technical Committee does not include specific technical guidance or battery requirements in the final product standard, lithium batteries, Ni Cd and Ni MH batteries, and cells used in portable systems shall comply with IEC 62133-1 (for nickel batteries) or IEC 62133-2 (for lithium batteries) standards. For products with non portable systems, other relevant standards may be considered for application.
