The fuse is usually printed on the CQC, CCC logo, other electronic products also have these two marks, what is the difference between the two? Simply put, CCC is a mandatory product certification, also known as 3C, some products in the catalog must be certified, otherwise they are not allowed to produce and sell. ; The full name of CQC is China Quality Certification Center, CQC is China's voluntary certification, voluntary principle.

We should first understand the two agencies, "China Certification and Accreditation Administration" (referred to as "CNCA" or "Accreditation Administration") is the development of safety certification policies and regulations of the national body; "China Quality Certification Center" (referred to as "CQC") is the specific implementation and management of the whole process of safety certification office. 3C Certification is actually the abbreviation of the English name "China Compulsory Product Certification" (China Compulsory Product Certification System), and is also a unified symbol of the country's compulsory product certification. Specifically for the national security certification (CCEE), import safety and quality licensing system (CCIB), China Electromagnetic compatibility certification (EMC) three-in-one "CCC" authoritative certification, the main characteristics are: the state announces a unified catalog, determine the unified application of national standards, technical rules and implementation procedures, develop a unified logo identification, the provision of unified charging standards. CQC is a national certification body (NCB) that represents China in the multilateral mutual recognition (CB) system of the International Electrotechnical Commission for Conformity Testing and Certification of Electrical Products (IECEE), and a national certification body that has joined the International Certification Alliance (IQNet) and the International Federation of Organic Agriculture Movements (IFOAM). The international mutual recognition business between CQC and many well-known certification bodies abroad, as well as extensive international exchanges, has a good international image.

So what exactly do the two symbols on the fuse represent? The fuses in the "Compulsory certification Product catalog (2010 updated version)" issued by the CNCA must go through the CCC compulsory certification. For electronic small fuses, all fuses produced according to the three national standards (commonly known as CCC standards) of "GB9364.1", "GB9364.2" and "GB9364.3" must be certified by CCC before they can be produced, sold and used.

The CNCA has also issued the "Mandatory product certification body (Announcement No. 35, 2012)", the CCC compulsory certification of fuse must be qualified, through the CNCA and CQC accredited testing institutions, according to the requirements of the mandatory certification standards, through the qualification test, and through the factory review, in order to obtain the CCC certification certificate. The current CCC certificate is valid for five years, the expiration of the need to continue to use, should be applied for within 90 days before the expiration, the validity period needs to pass the factory supervision and testing every year.

The small fuses used on the market are not covered by the above three CCC standards, and a large part of the fuses are not produced in accordance with CCC standards, and this part of the fuse can not be CCC mandatory certification, only possible to apply for CQC voluntary certification. For electronic small fuses, most of the indicators basically meet the national standard (GB) or international standard (IEC) products can apply for voluntary certification, voluntary certification and compulsory certification in China is equally valid.

Testing institutions that do voluntary certification also need to be recognized by CNCA and CQC, and the standard text based on the test also needs to be reviewed and approved by CQC in advance. Only according to the requirements of the recognized standards, through the qualification test, and also through the factory review, in order to obtain the CQC certification. The validity period of the CQC certification is also five years, and it is also necessary to pass the factory supervision and testing every year during the validity period.

The acceptance of applications for CCC compulsory certification and CQC voluntary certification, the allocation of test structures (you can also choose), the review of test reports and the issuance of certificates are all completed by the "China Quality Certification Center" (referred to as CQC). Product sample delivery and testing can be carried out by recognized testing institutions, test reports need to be reviewed and approved by CQC, certificate issued by CQC unified number, in the CQC website can be based on the application company name, production company name, certificate number and other ways, to find all the CCC and CQC certificates.

China is a member of the IEC organization and a member of the CB organization, and can pass the CCC certification or CQC certification in exchange for certification from other member states. If you apply for CCC certification or CQC certification at the same time also apply for CB report, you can get two reports a test, CCC report or CQC report is used to obtain CCC certificate or CQC certificate, CB report is used to apply for conversion to other CB member states certification.
