▍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?

Overview of the Standard General Specification for the Space-using Li-ion Storage Battery was put forward by China Aerospace Science and Technology Corporation and issued by ShanghaiInstitute of Space Power-Sources. Its draft has been on public service platform tocanvass opinion. The standard gives regulations on the terms, definition, technical requirement, test method, quality assurance, package, transportation and storage of Li-ion storage battery. The standard applies for the space-using li-ion storage battery (hereinafter referred to as “Storage Battery”) Appearance and mark
The appearance should be intact; the surface should be clean; the parts andcomponents should be complete. There should be no mechanical defects, no extras and other defects. The product identification shall include the polarity and traceable product number, where the positive pole is represented by “+” and the negative pole isrepresented by “-”.
Dimensions and weight
The dimensions and weight should be consistent with the technical specifications of thestorage battery.
AirtightnessThe leakage rate of the storage battery is not more than 1.0X10-7Pa.m3.s-1; after the
battery is subjected to 80,000 fatigue life cycles, the welding seam of the shell should not be damaged or leaked, and the burst pressure should not be lower than 2.5MPa.For the requirements of tightness, two tests are designed: leakage rate and shell burst pressure; the analysis should be on test requirements and test methods: these requirements mainly consider the leakage rate of the battery shell under low pressure conditions and its ability to withstand gas pressure.
