UN Model Regulations on the Transport of Dangerous Goods Rev. 22 release,

▍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?

In November, the United Nations economic commission for dangerous goods transportation team released the UN dangerous goods regulations proposal template version 22, this regulation model is mainly for a variety of transportation way to provide a basic operation requirements, to provide reference for air, sea and land transportation, the direct reference in the process of actual transportation is not much. This standard is
used in the drop test of lithium batteries. This model regulation and the “tests and Standards” are a series of standards, used together, updated every two years.
The contents of this change related to lithium battery mainly include the following aspects. The most significant change is the change of operating mark of lithium battery. The details are shown in the following table:The CE mark is only applicable to products within the scope of EU regulations. Products bearing the CE mark indicate that they have been assessed to comply with EU safety, health and environmental protection requirements. Products manufactured anywhere in the world require the CE mark if they are to be sold in the European Union.
