Battery CB certification
1. Introduction to CB certification
The CB system (IEC system for conformity testing and certification of electrical products) is an international system operated by IECEE. The certification bodies of each member country of IECEE test the safety performance of electrical products on the basis of IEC standards. The test results are the CB test report and CB The test certificate is a system of mutual recognition among the member states of IECEE. Up to now, 66 certification bodies in 51 countries and more than 270 CB laboratories under their jurisdiction have participated in this mutual appointment system. The purpose is to reduce international trade barriers due to the need to meet the certification or approval criteria of different countries. IECEE is the abbreviation of the International Electrotechnical Commission's Electrotechnical Product Conformity Testing and Certification Organization
Second, the role of CB
After the enterprise obtains the CB certificate from one of the certification bodies, due to the mutual recognition agreement, it is no longer necessary to repeat the test. Only report audit and supplementary test or national difference test can be converted into the safety certification certificate of other member states.
Third, the battery CB certification product range:
Portable sealed secondary battery cells and batteries (groups) containing alkaline or non-acid electrolyte
IEC62133 test standard:
Secondary cells and batteries (groups) containing alkaline or non-acid electrolytes: portable sealed secondary cells and safety requirements for batteries (groups) used in portable devices.
Fourth, the battery IEC/EN 62133 test has the following items
Cell: Continuous low rate charging, vibration, temperature cycling, external short circuit, free fall, shock (collision), thermal misuse (thermal shock), extrusion, low air pressure, overcharge, forced discharge, high rate charging Protection function (lithium system), marking and packaging, improper installation (nickel
system).
Battery: Vibration, shell stress at high temperature, temperature cycling, external short circuit, free fall, impact (collision), labeling and packaging, overcharge (nickel system).
