CB,
▍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.
On October 14, 2021, National Public Service Platform for Standards Information released public information of a proposed project, Safety requirements for secondary lithium cells and batteries for use in electrical energy storage systems.The purpose of this standard is to reduce the safety accidents of fire and explosion when lithium batteries are used in the field of electrical energy storage, meanwhile to improve the product quality of lithium batteries for electrical energy storage.
Applicable scope of the standard specifies the safety requirements and tests for secondary lithium cells and batteries for use in electrical energy storage systems with a maximum DC voltage of 1500 V (nominal). The following are some examples of the use of secondary lithium cells and batteries equipment within the scope of this document: Telecommunications-central emergency lighting and alarm system
Start of stationary engine Photovoltaic system Household (residential) energy storage system (HESS)
Large-capacity energy storage: on-grid/off-grid This standard applies to uninterruptible power supply (UPS) batteries and battery packs, but it does not apply to portable systems smaller than 500Wh to which IEC 61960 applies.
