Battery CB Certification Testing Laboratory

The CB scheme was established by the International Electrotechnical Commission (IECEE) to provide a means for participating safety certification bodies to cooperate and mutually recognize CB certificates (CBTC) and test reports (CBTR) issued by one another as a basis for issuing national certification marks or standards. Currently, the CB scheme has over 50 member countries across the Americas, Europe, Asia, Australia, and Africa, with at least one product certification body in each member country recognized by IECEE as a National Certification Body (NCB). Each NCB oversees at least one CB Testing Laboratory (CBTL) that issues test reports on its behalf, which the NCB directly recognizes to issue CB certificates.

Why Obtain Battery CB Certification?

1. Direct Recognition or Approval by Member Countries: With CB test certificates and CB test reports, your products can be directly exported to certain countries.

2. Facilitate Conversion to National Certifications: CB certificates can be directly converted into member countries' certification certificates by providing the CB certificate, test report, and difference test report (if applicable), eliminating the need for retesting and shortening the certification cycle.

3. Ensure Product Safety: CB certification testing considers the safety of products under reasonable use and foreseeable misuse. Certified products demonstrate compliance with safety requirements.
