▍Important Certification profile “CB Certification- -IEC 62619 CB Certification profile CB Certified IEC(Standards.The goal of CB certification is to “use more” to promote international trade; The CB system is an international system of the (Electrical Qualification Testing and Certification System) operating on the IECEE, called short for the IEC Electrical Qualification Testing and Certification Organization. “The IEC 62619 is available for: 1. Lithium batteries for mobile equipment: forklift trucks, golf carts, AGV, railway, ship. . 2. Lithium battery used for fixed equipment: UPS, ESS equipment and emergency power supply “Test samples and certification period
