CMA is the abbreviation of China Metrology Accreditation. Only the third-party inspection organization with CNAs certification is allowed to apply CMA chapter on the inspection report, and CMA can be applied on the inspection certificate report according to the new items allowed on the qualification certificate. The test report with CMA seal can be used as a product quality evaluation, effectiveness and appraisal institution, which is legally recognized. Cmacnas certification and CNAs laboratory identification, as common verification of inspection reports, have not only common points but also some differences.

CMA is also the mark of CNAs certification certificate of testing center. The organization with this mark is a reasonable and legal inspection organization. According to the relevant requirements of the product quality law of the people's Republic of China, organizations engaged in national inspection and testing of goods in China must have the independent subject qualification, and the CNAs certification management method units at the national or provincial level will review and meet the standards with the review organization. Only after they are set or authorized according to the regulations can they engage in inspection and testing activities.

CNAs is the abbreviation of China National Accreditation Service for conformity assessment. CNAs determines whether it has the strength to carry out relative quality certification theme activities (such as verification, inspection and correction, inspection, etc.), determine the credibility of its quality certification theme activities, and give full play to its effectiveness according to the management methods and theme activities of comment and supervision quality certification organizations (such as authoritative certification, laboratory, inspection organization).

China's quality certification and China's recognition rules and regulations have long been integrated into the international recognition bilateral agreement management system, and have a vital influence and give full play to the vital effect in the international recognition bilateral agreement management system. According to the relevant agreements on China's accession to the WTO, "CNAs" indicates that it can obtain bilateral agreements internationally (for example, it can be recognized by the United States, Japan, France, Germany, Britain and other countries). CNAs laboratory agrees that the report presented is a measurement and testing report. The corrected results only identify the numerical deviation of the accurate measurement equipment to ensure the accuracy of the value, and do not stipulate the judgment of reaching the standard or failing to pass the standard. "Calibration certificate" or "calibration report" can be obtained at the end of calibration.

The differences between cmacnas certification and CNAs laboratory identification are introduced in detail from the aspects of characteristics, legal provisions, available objectives, review basis, application fields and so on.

1. Characteristics

CMA is the recognition of administrative departments enforced by government departments. According to the Metrology Law of the people's Republic of China, in order to ensure the accuracy, fairness and impartiality of inspection information, all quality inspection units that produce impartial inspection reports to social development must obtain the qualification certificate of "CNAs certification", otherwise it will constitute a violation of the regulations.

CNAs identity belongs to the self-directed personal behavior of the structure.

2. Legal provisions

The laws and regulations for cmacnas certification are Article 22 of the Metrology Law of the people's Republic of China, and the legal provisions recognized by CNAs laboratory are GB / t27025-2008 (ISO / IEC17025:2005 is selected equally).

3. Available targets

CMA key uses third-party testing organizations.

CNAs can be used to target all institutions engaged in the theme activities of the laboratory, including those laboratories that take inspection or correction as part of the regular inspection and product quality certification.

4. Application field

CMA is reasonable in China and presents the fairness inspection report to the whole country,

CNAs is under international bilateral agreements.

5. Review basis

The review basis of cmacnas certification is the evaluation criteria for laboratory qualification (change and selection, review and filling provisions, application and handling specifications, etc.).

The review of CNAs laboratory accreditation is based on CNAs / cl01:2006 criteria for accreditation of testing and calibration laboratories (selected equally).

6. Management method, review organization

CMA is reviewed and managed by CNCA (China National Certification and Accreditation Administration), quality supervision units of people's governments of provinces, cities, autonomous prefectures, municipal districts and national CMA measurement certification industry review team.

CNAs is reviewed and managed by China conformity assessment and Accreditation Commission.

7. Review procedures and regulations

The review procedures, procedures and regulations of CMA vary from region to region, and the details must be understood by the local Quality Supervision Bureau. The evaluation and regulations of CNAs are unified throughout the country and internationally.

8. Application scope and characteristics

Cmacnas certification can give public data information within the scope of evaluation. It is universal in China, and CNAs laboratory identification is a common international practice. CNAs has signed bilateral agreements with laboratory identification and international laboratory identification institutions in the Asia Pacific region, but it can not replace verification identification and qualification identification.
