Electronic components belong to industrial equipment, most of which can not be seen in daily life, because they are deployed in mobile phones, computers and intelligent devices. There are basically thousands of components. Different devices carry different functions, including high-tech RF equipment in addition to resistors and capacitors. There are many kinds of electronic components. The number of models involved in all kinds of electronic components is hundreds of millions. The market demand for electronic components is also very large, because electronic components have become an indispensable part in the industrial field. When we are not sure whether the quality of components is true or false, we can directly test the purchased electronic components. There are special testing institutions in China to help test the quality of components.

The third-party testing institutions started very late in China, basically after 2000. At the beginning of the economy in Europe and America in the 15th century, in order to ensure product quality, there were third-party testing institutions involved. The involvement of mature third-party testing institutions in commodity testing has become very common in the 19th century and has become a conscious business behavior. The current situation of domestic testing is that domestic products are in the charge of national testing institutions, such as the Bureau of quality supervision and the center for disease prevention, while exports are mainly in the charge of foreign testing institutions, and domestic third-party testing institutions are also developing rapidly.

What is the role of the third-party component testing organization?

The third-party component testing institutions generally represent impartiality, fairness, openness and certain independence. Commodity inspection activities conducted in an impartial and authoritative non party capacity in accordance with relevant laws, standards or contracts. The existence of independent third-party testing enterprises has its own special significance. It is not only an effective supplement to government supervision, help the government get rid of the "trust crisis", but also provide support for industrial transformation and upgrading, and provide a strong service platform for industrial development. With the improvement of people's living standards and the intensification of international trade barriers, China's third-party testing industry has developed rapidly.

Qualification of third-party testing organization

CNAS：China National Accreditation Service for conformity assessment (CNAs) is a national accreditation institution approved and authorized by the national certification and Accreditation Administration in accordance with the regulations of the people's Republic of China on certification and accreditation. It is responsible for the accreditation of certification institutions, laboratories, inspection institutions and other relevant institutions.

CMA：The product quality inspection institution that has obtained the certificate of metrological certification may inspect according to the requirements specified in the certificate

For the new version of CMA project, the metrological certification mark is used on its product inspection report. The mark is composed of the figure formed by the three English letters of CMA and the number of the metrological certification of the inspection organization. CMA is composed of the first capital letter of the three English words China Metrology Accreditation, which means "China Metrology Certification". Now it is renamed qualification recognition, and the qualification is also different.

CNAS：It is a national accreditation institution approved and authorized by the national certification and Accreditation Administration, which is responsible for the accreditation of certification institutions, laboratories, inspection institutions and other relevant institutions. Cmaf: qualification certificate of food inspection agency, which is required by food inspection agency. (Note: according to the management measures for qualification recognition of inspection and testing institutions, cmaf certificate and CMA certificate have been officially merged into CMA certificate since August 1, 2015)
