▍What is CB Certification？
IECEE CB is the first genuine international system for mutual recognition of electrical equipment safety test reports. NCB (National Certification Body) reaches a multilateral agreement, which enables manufacturers to obtain national certification from other member countries under CB scheme on the basis of transferring one of the NCB certificates.
CB certificate is a formal CB scheme document issued by authorized NCB, which is to inform other NCB that the tested product samples conform to present standard requirement.
As a kind of standardized report, CB report lists relevant requirements from IEC standard item by item. CB report not only provides results of all required testing, measurement, verification, inspection and assessment with clearness and non-ambiguity, but also including photos, circuit diagram, pictures and product description. According to the rule of CB scheme, CB report will not take effect until it presents with CB certificate together.
▍Why we need CB Certification?
- Directly recognized or approved by member countries
With CB certificate and CB test report, your products can be exported to some countries directly.
- Convert to other countries certificates
The CB certificate can be directly converted to the certificate of its member countries, by providing the CB certificate, test report and difference test report (when applicable) without repeating the test, which can shorten the lead time of certification.
- Ensure the Safety of Product
The CB certification test considers the product’s reasonable use and foreseeable safety when misused. The certified product proves the satisfactory of the safety requirements.
▍Why MCM?
● Qualification: MCM is the first authorized CBTL of IEC 62133 standard qualification by TUV RH in mainland China.
● Certification and testing capability: MCM is among the first patch of testing and certification third party for IEC62133 standard, and has finished more than 7000 battery IEC62133 testing and CB reports for global clients.
● Technical support: MCM possesses more than 15 technical engineers specialized in testing as per IEC 62133 standard. MCM provides clients with comprehensive, accurate, closed-loop type of technical support and leading-edge information services.
Each manufacturer will have the responsibility to use components with relevant registration (R-no.) in case the component is covered in CRS. It is important to note that the manufacturer here refers to the manufacturer of the test product. If the battery test is carried out, and the cell is not yet evidence, the battery manufacturer shall provide a letter of commitment; Similarly, if the test of the terminal product mobile phone is carried out, and the battery cell, battery and adapter of its components are not obtained, the mobile phone manufacturer needs to provide a letter of commitment; If the cell, battery, adapter and mobile phone are tested at the same time, the manufacturers of the latter three requirements will need to provide a letter of commitment. The cell manufacturer is not required to provide a letter of commitment under any circumstances.Products such as batteries can be tested without having to wait for a BIS certificate for a previously tested component. Under parallel testing, the lab will test the first component & issue test report. This test report no. along-with name of lab will be mentioned in the test report of the second component. This procedure will be followed for subsequent components & final product also. The battery & final product testing laboratory shall evaluate the previously tested components before generating the final test report.
