The CB system is an international system operated by the "International Electrotechnical Commission Qualification Testing and Certification Organization for Electrical Products" (IECEE). The certification bodies of the member countries of IECEE test the safety performance of electrical products based on the IEC standard.
1. IECEE
The full name of IECEE is "International Electrotechnical Commission Qualification Testing and Certification Organization for Electrical Products". It is an international certification organization under the International Electrotechnical Commission (IEC).
The purpose of IECEE is to promote the international trade of electrical products mainly used in homes, offices, workshops, health care and similar places.
The ultimate goal of IECEE to promote international certification is: an electrical product, the same IEC standard, a test, a conformity assessment, for global acceptance.
2. IECEE-CB system
The IECEE-CB system is "a system of mutual recognition of test certificates for electrical products". The system is based on mutual recognition (two-way acceptance) test results among members participating in the CB system to obtain national certification or approval, so as to achieve the purpose of promoting international trade. The CB system is suitable for electrical products within the scope of the IEC standards adopted by IECEE. The CB certificate is a document issued by a certification body with certification and accreditation to participate in the CB system. The CB certificate is only valid when the relevant CB test report is attached.
The execution unit of the CB system is each national certification body (NCB) accepted according to the CB system rules. The NCB also uses the CBTL (CB testing laboratory) accepted according to the CB rules.
3. Lithium battery CB certification product range
Portable sealed secondary battery cell and battery (group) containing alkaline or non-acid electrolyte
Lithium battery CB certification test standard
IEC 62133
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
4. Main test items of CB certification for lithium batteries:
Cell (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, improper installation (nickel system).
Battery: Vibration, shell stress at high temperature, temperature cycling, external short circuit, free fall, impact (collision), marking and packaging, overcharge (nickel system electricity: I5O-I403-I958).
5. Advantages of lithium battery CB certification
The vast majority of electronic and electrical products need to meet different regulations when they enter countries. In the past, obtaining product safety certifications from various countries was a difficult and time-consuming process. But now relying on the CB system, manufacturers can obtain safety certifications from more than 50 countries at a time.
After the test is successfully completed, a CB test certificate and corresponding CB test report will be issued for the product. The combination of the certificate and the report constitutes an international pass. The manufacturer can apply for national certification of any national certification body in any country or region that participates in the CB system, and usually no additional testing is required.
6. The main objectives of the CB system
To promote international trade, the means is to promote the unified coordination of national and international standards and the cooperation of product certification agencies, so that manufacturers are closer to the ideal test, a globally recognized goal. The advantage of obtaining a CB certificate is that when applying for certification in various countries, the CB report can greatly save time and costs.
