In the calibration industry, qualification is a very important part of the calibration industry, qualification can be said to be a threshold, want to carry out all kinds of instrument calibration business, must meet a series of qualifications. In the calibration industry, the most important qualifications are CMA and CNAS qualifications, which are difficult to obtain in the calibration industry and have strong versatility, so what is the essence of these qualifications for the organization? Which is more practical for businesses?

CMA definition

CMA is ChinametrologyAcredidation shorthand (China CNAS certification/approval), the qualification is to belong to domestic characteristic identification. In the international CMA qualification is not very meaningful, but in the country, it is a relatively authoritative qualification, and generally only authoritative institutions have this qualification. The use of CMA qualifications is also divided into circumstances, generally there is a clear CMA demand, the CMA mark will be used in the certificate. The use of CMA qualification allows the certificate to have legal attributes and be recognized and used by law.

CNAS definition

CNA be Chinanationalaccreditationserviceforconformityasssment (China national accreditation committee of qualified assessment), and CMA, CNAS is internationally recognised general qualifications, with CNAS logo, That is, it represents its standard conditions and meets international requirements. If CMA is a domestic authoritative qualification, then CNAS is an international authoritative qualification. What do these two qualifications mean for the calibration industry? CMA for calibration institutions, is a link linked to the authority attribute, the general institution is very difficult to obtain, is recognized by the relevant departments will give the qualification of the institution, the institution can not take the initiative to apply for it, so there are not many institutions with CMA qualification, if which institution has CMA qualification, it can be said to have a very good hard power. The difficulty of obtaining CNAS is slightly lower, and CNAS can be actively applied by the institution and obtained after the evaluation. However, CNAS has a certain range, it is not a fixed qualification, CNAS qualification scope will be specific to a certain type of instrument 1, can not directly cover all instruments, so in order to expand the coverage of CNAS, the organization will continue to expand the scope of calibration capacity every year. Pragmatically, for enterprises, it should be divided according to the situation. CMA is usually for verification needs, generally the qualification of verification institutions, CNAS is part of the calibration needs, in some audits must be on the certificate CNAS chapter will be used. The range of verified instruments is not large, and the calibration is relatively extensive, so the practical CNAS application will be more guarded. Therefore, most of the calibration institutions are equipped with CNAS qualification, but after the institution obtains CNAS qualification, it does not mean that everything is fine, and the authority will review and supervise the CNAS qualification of the institution. If the institution has illegal operation, it will cancel the CNAS qualification of the institution.
