1. Laboratory Qualification and Original China CMA Metrology Certification Consultation (China Metrology Accreditation) Legal Basis

The "Product Quality Law" stipulates that "product quality testing institutions must possess the corresponding testing conditions and capabilities. Only after passing the assessment by the provincial or higher quality supervision department or its authorized department, and obtaining the metrological certification review supervised by the National Certification and Supervision Commission, can they undertake product quality testing work." The metrological certification review is primarily based on the "Criteria for the Assessment of Laboratory Qualification," with the relevant regulations formulated according to the "General Requirements for the Competence of Testing and Calibration Laboratories."

2. CMA metrological certification is a mandatory action

The metrological certification assesses and verifies the metrological inspection, testing capabilities, and reliability of product quality inspection institutions that provide fair data to society. It is a means for the national metrological administration to evaluate whether these institutions possess the conditions and qualifications to provide公证 data to the public.

Why Obtain a CMA Measurement Certification Certificate

Certification for metrological verification is the entry permit for many industry testing institutions to enter the market. Without obtaining this certificate, testing institutions are prohibited from conducting tests. Especially in industries that directly concern the vital interests of the general public, whether a testing institution has passed metrological certification can serve as an effective evaluation tool when assessing their testing capabilities.

Only institutions with a valid metrological certification can use the CMA mark on their product inspection reports as specified by the certificate. Reports stamped with the CMA can be used for product quality assessment, outcomes, and legal matters, and the metrological test data serves as fair data with legal efficacy.

This confirms the authoritative status of certified measurement institutions in product quality inspection, with their provided data and results applicable to the following aspects:

(1) Develop and implement various policies and guidelines based on relevant test results.

(2) Research departments use detection data to uncover new phenomena, develop new technologies, and new products.

(3) Producers use detection data to determine their production activities.

(4) Consumers use test results to protect their interests.

(5) The circulation sector uses detection data to determine its buying and selling activities.

How to Properly Conduct Laboratory Metrological Certification Work

Firstly, determine the scope of laboratory metrological certification. The scope of laboratory metrological certification serves as the basis for the detection reports with the CMA metrological certification seal provided by the laboratory. The current scope of metrological certification is determined and published by the "Appendix to the Qualification Identification Metrological Certification Certificate." The determination of the certificate appendix focuses on the standards of the tested products or parameters, providing relevant evidence for the issued detection reports.
