Initially, the CB system was initiated by CEE (the former European "National Committee for Qualification Testing of Electrical Equipment") and merged into IEC in 1985. The IECEE CB system is the first truly international system for mutual recognition of electrical product safety test reports. The national certification bodies (NCB) of various countries have formed a multilateral agreement, and manufacturers can obtain the national certification of other member states of the CB system with a CB test certificate issued by NCB.

The CB system is based on the international IEC standard. If the national standards of some member states are not fully consistent with the IEC standards, national differences are also allowed, but they should be announced to other members. The CB system uses the CB test certificate to verify that the product samples have successfully passed the appropriate tests and meet the relevant IEC requirements and the requirements of the relevant member states.

The main goal of the CB system is to promote international trade. Its means are to promote the harmonization of national and international standards and the cooperation of product certification agencies to bring manufacturers closer to the ideal "one test, multiple applications" goal.

the term

IECEE stands for "The IEC System for Conformity Testing and Certification of Electrical Equipment"-"International Electrotechnical Commission's organization for conformity testing and certification of electrical products." The official name of the CB system is "Scheme of the IECEE for Mutual Recognition of Test Certificates for Electrical Equipment"-"IECEE Mutual Recognition of Test Certificates for Electrical Products". The abbreviated name of the CB system means "Certification Bodies' Scheme"-"Certification Bodies' Scheme".

System scope

The products covered by the CB system are products within the scope of the IEC standard recognized by the IECEE system. When three or more member states announce that they hope and support a certain standard to join the CB system, the new IEC standard will be adopted by the CB system. The IEC standards used are published on the CB bulletin and the IECEE website.

Electromagnetic compatibility (EMC) is not included in the CB system unless the IEC standard used specifically requires it. However, the CB system has begun to investigate its members' willingness to conduct EMC measurements together with safety testing. The results of this survey will be published in the CB Bulletin on this subject.
