What is Battery CB Certification?

What is CB? 

CB is a system established by the International Electrotechnical Commission (IECEE), aimed at providing a cooperative pathway for safety certification bodies involved in this scheme. It facilitates mutual recognition of CB Certificates (CBTC) and CB Test Reports (CBTR) issued by participating bodies, which serve as a reference for issuing national certification marks or standards.

Currently, 53 countries globally are members of the CB system, spanning the Americas, Europe, Asia, Australia, and Africa. Multilateral agreements exist between National Certification Bodies (NCBs) of these countries, allowing manufacturers to obtain national certifications from other CB system member countries based on the CB Test Certificate issued by an NCB. The CB system is based on international IEC standards. If a member country's national standards differ from IEC standards, national deviations are allowed but must be disclosed to other members.

Why Obtain Battery CB Certification?

1) **Direct Recognition or Approval**: With a CB Test Certificate and Test Report, your product can be directly exported to certain countries.

2) **Certificate Conversion**: A CB Certificate can be directly converted into a national certification of a member country. By providing the CB Certificate, Test Report, and a report covering any national deviations (if applicable), redundant testing can be avoided, reducing certification time.

3) **Ensuring Product Safety**: CB certification tests account for both normal and foreseeable misuse of the product. Products that pass CB certification demonstrate compliance with safety requirements.
