The OD - 2037 version 4.3 of the CB certificate rule operation document newly released by the International Electrotechnical Commission IECEE officially came into effect on January 1, 2024. This document has made key updates to CB certificates in terms of functional safety, product multi - standards, model naming, separate certification of software packages, battery standards, etc.

Expression of Functional Safety Information:
New Chapter 2.4: Add functional - safety - related descriptions in the CB certificate, covering electrical characteristics, safety levels (such as SIL, PL) and safety functions. The functional safety report is included in the CB certificate as additional information.
Handling of Multiple Standards for the Same Product:
New Chapter 6.3: It is allowed to issue one CB certificate for products covering multiple categories and standards (such as power supplies), provided that all relevant test reports are provided.
Differentiation of Product Models:
New Chapter 8.4: For products with different hardware and software configurations, each configuration must have a unique model name.
Issuance of Separate CB Certificates for Independent Software Packages:
Supplementary Chapter 10.1: For independent software packages that provide product safety measures, separate CB certificates and reports can be issued.
Application of Battery Standards:
Supplementary Chapter 10.7: Determine the applicable standards for batteries in different applications. For example, IEC 62133 - 1 or IEC 62133 - 2 is used for portable systems, and other relevant standards may be applicable for non - portable systems.

Emphasis on Functional Safety:Enterprises need to pay attention to the evaluation and reporting of product functional safety to ensure compliance with the new regulations.
Integration of Standards:When a product complies with multiple standards, it is necessary to integrate the test reports of different standards to apply for a CB certificate.
Standardization of Model Naming:Ensure that the model naming of products with different configurations complies with the new regulations.
Certification of Independent Software Packages:Separate certification of software packages may require more detailed review and evaluation.
Applicability of Battery Standards:Enterprises need to select appropriate battery standards based on the specific applications of their products.

This update by IECEE has strengthened the focus on functional safety and multi - standard integration, while providing clear guidelines for software packages and battery standards. Enterprises need to update their compliance strategies in a timely manner to adapt to these changes.
