CB certification
1 Introduction
The CB system is a global mutual recognition system established by the International Electrotechnical Commission (IECEE). 45 accreditation bodies from 34 countries around the world participate in this mutual recognition system. The member states and member institutions of this organization are expanding. After obtaining the CB certificate from one of the certification bodies, the enterprise can more easily convert into the certification certificate of other institutions, thereby obtaining the access permit to enter the relevant national market.
The CB Report is a standardized report that lists the requirements of the relevant IEC standards in a tabular list. The report provides the results of all tests, measurements, verifications, inspections, and evaluations required, and these results should be clear and unambiguous. The report also includes photos, circuit diagrams, images, and product descriptions. According to the rules of the CB system, the CB test certificate is valid only when provided together with the CB test report.
2. Terminology
IECEE stands for "The IEC System for Conformity Testing and Certification of Electrical Equipment" - "International Electrotechnical Commission‘s Electrical Product Qualification Testing and Certification Organization". The official name of the CB system is "Scheme of the IECEE for Mutual
Recognition of Test Certificates for Electrical Equipment" – “IECEE Electrical Product Test Certificate Mutual Recognition System”. The abbreviated name of the CB system means “Certification Bodies’ Scheme” – “Certification Authority System”.
3. System scope
The products covered by the CB system are products within the scope of the IEC standard recognized by the IECEE system. When more than three member states declare that they want 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 Gazette and the IECEE website.
Electromagnetic compatibility (EMC) is not included in the CB system unless specifically required by the IEC standard used. However, the CB system has begun to investigate their members‘ willingness to conduct EMC measurements along with safety testing. The results of this survey will be published in the CB Bulletin on this subject.
Lithium battery application for CB certification
Standard: IEC62133 (cell, battery)
Other requirements for lithium battery cb certification:
CB to CB to recognize the national standard deviation of the test can be transferred, which goes to Japan, South Korea, France, Switzerland, four countries need to increase the strong internal circuit short-circuit test
