Battery CB certification testing scope and test items——ZRLK

The CB system (IEC system for conformity testing and certification of electrical products) is an international system operated by IECEE. The certification bodies of IECEE member states test the safety performance of electrical products based on IEC standards. The test results are the CB test report and the CB system. The system of mutual recognition of test certificates in IECEE member countries. The purpose is to reduce the barriers to international trade that arise from having to meet different national certification or approval criteria. IECEE is the abbreviation of International Electrotechnical Commission Electrotechnical Product Qualification Testing and Certification Organization.

CB certification provides evidence that a representative sample of a product has successfully passed the test, indicating that it meets the requirements of the relevant IEC standard. Upon successful completion of the test, a CB test certificate and corresponding CB test report will be issued to the product. Together, these two documents constitute a passport that allows manufacturers to apply for global certification from any national certification body in any country or region participating in the CB system, usually without additional testing. CB is mainly used for certificate transfer, such as: products with CB certificate need to be converted to CE certification of the European Union or FCC certification of the United States, which will greatly reduce the cost and cycle and quickly enter new markets. If you want to sell products in some countries that do not have their own certification, you can do CB certification to show that the product has obtained international certification or approval.
