CB certified

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 countries are based on IEC standards.

The safety performance of electrical products is tested, and the test results, that is, the CB test report and the CB test certificate, are mutually recognized in the IECEE member countries. Up to now,

A total of 66 certification bodies in 51 countries and more than 270 CB laboratories under them have participated in this mutual appointment system. The purpose is to reduce the need to meet different

International trade barriers arising from national certification or approval of guidelines. IECEE is the abbreviation of International Electrotechnical Commission Electrotechnical Product Qualification Testing and Certification Organization

The role of CB

After the enterprise obtains the CB certificate from one of the certification bodies, due to the mutual recognition agreement, it can no longer conduct repeated tests, but only do report audits and supplementary tests or national

The difference test can be converted into the safety certification certificate of other member states.

Portable sealed secondary battery cells and batteries (packs) containing alkaline or non-acidic electrolytes

IEC62133 test standard:

Secondary cells and batteries (groups) containing alkaline or non-acid electrolytes: Safety requirements for portable sealed secondary cells and batteries (groups) used in portable equipment.

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), labeling and packaging, incorrect installation (nickel system).

Battery: Vibration, case stress at high temperature, temperature cycling, external short circuit, free fall, shock (collision), marking and packaging, overcharge (nickel system).
