What is CB certification / IEC certification 1. Compulsory product certification is only recognized by China's accession to IECEE-CB system standards within the directory CB certificate. 2. CB certificate recognized by the certification body retains prototype verification and complement national standards do differ rights (CB report with national standards even if differences in test content). 3. CB certificate should be valid, the specific judgments are as follows: (a) with the corresponding CB report. (2) IECEE-CB CB certificate issued within the system with a full member of qualifications within its capabilities CB certificates and reports issued, and the presentation standards must be our (NCB) within the scope of accreditation standards. (3) that issued the certificate is based on the standards should not be lower than the current standard of the corresponding IEC standard version. (4) CB certificate has been more than three years, NCB should be questioned. (5) CB Certificate and CB report appears "ROC" (Republic of China) words are not recognized. 4.CB report key pieces in principle be recognized, but it should verify the information reported in parts and certified to meet the standard information, and to verify the applicability of component selection, reserved the right to review. 5.CB reports and CB certificate of product models, specifications, manufacturers and production plants must apply for compulsory product certification models, specifications, manufacturers, factories consistent (or cover), any of which are inconsistent, not be accepted. 6.CB certificate applicant and the application for compulsory product certification applicants should in principle be the same.

CB system (electrical equipment conformity testing and certification of the IEC system) is the IECEE operations - an international system, IECEE Certification Body in the Member States based on IEC standards for electrical product safety testing, the test results that CB test report and CB test certificate in IECEE Member States to obtain mutual recognition system. Purpose is to reduce the need to meet different national certification or approval criteria arising from international trade barriers. IECEE is the International Electrotechnical Commission IEC product qualification testing and certification organization for short. Development initially, CB system consists CEE (former European "Electrical Equipment Certification Test National Committee") initiated in 1985 into the IEC. IECEE CB electrical product safety system is the mutual recognition of test reports first truly international system. Is formed between the in the each country's national accreditation body (NCB) multilateral agreements, manufacturers can to by virtue of the a NCB-issued by the CB test certificate OF of of other Member States to obtain IN CONNECTION WITH THE CB system WHICH national certification. The based on of the CB system the international IEC standard. If the the of the national standards of some Member States is still can not fully be consistent with the the IEC standard, but also allows the the the existence of of the national differences, but should be made announced to other members of the. The take advantage of of the CB system CB test certificate in to to confirmed that product samples have successfully passed the the appropriate test, and in the interests of the the requirements of of the relevant IEC requirements and interested Member States. CB system's main objective is to promote international trade, which means that through the promotion of national standards with international harmonization of standards and product certification bodies, leaving the manufacturer closer to the ideal of "one test, many for" goal.
