▍What is CB Certification？

IECEE CB is the first genuine international system for mutual recognition of electrical equipment safety test reports. NCB (National Certification Body) reaches a multilateral agreement, which enables manufacturers to obtain national certification from other member countries under CB scheme on the basis of transferring one of the NCB certificates.

CB certificate is a formal CB scheme document issued by authorized NCB, which is to inform other NCB that the tested product samples conform to present standard requirement.

As a kind of standardized report, CB report lists relevant requirements from IEC standard item by item. CB report not only provides results of all required testing, measurement, verification, inspection and assessment with clearness and non-ambiguity, but also including photos, circuit diagram, pictures and product description. According to the rule of CB scheme, CB report will not take effect until it presents with CB certificate together.

▍Why we need CB Certification?

1. Directly recognized or approved by member countries

With CB certificate and CB test report, your products can be exported to some countries directly.

1. Convert to other countries certificates

The CB certificate can be directly converted to the certificate of its member countries, by providing the CB certificate, test report and difference test report (when applicable) without repeating the test, which can shorten the lead time of certification.

1. Ensure the Safety of Product

The CB certification test considers the product’s reasonable use and foreseeable safety when misused. The certified product proves the satisfactory of the safety requirements.

▍Why MCM?

The meeting of UN TDG held from November 29 to December 8, 2021 has approved a proposal which is concerned about amendments to sodium-ion battery control. Committee of experts plans to draft amendments to the twenty-second revised edition of the Recommendations on the Transport of Dangerous Goods, and Model Regulations (ST/SG/AC.10/1/Rev.22).
Amended content:
Revision to Recommendations on the Transport of Dangerous Goods
2.9.2 After the section for “Lithium batteries”, add a new section to read as follows: “Sodium ion batteries”.For UN 3292, in column (2), replace “SODIUM” by “METALLIC SODIUM OR SODIUM ALLOY”. Add the following two new entries:For SP188, SP230, SP296, SP328, SP348, SP360, SP376 and SP377, modify special provisions; for SP400 and SP401, insert special provisions (Requirements for sodium-ion cells and batteries contained in or packed with equipment as general goods for transportation)
Follow same labeling requirement as lithium-ion batteries
Amendment to Model Regulations
Applicable scope: UN38.3 is not only applicable to lithium-ion batteries, but also sodium-ion batteries
Some description contained “Sodium-ion batteries” are added with “Sodium-ion batteries” or deleted of “Lithium-ion”.Add a table of test sample size: Cells either on standalone transportation or as components of batteries are not required to undergo T8 enforced discharge test.
