China Metrology Accreditation (CMA)
20. November 2023China Metrology Accreditation (CMA) is an organization responsible for the accreditation of measurement and testing laboratories in China. The CMA’s mandate is broad and it works closely with numerous organizations and Chinese regulatory authorities. This is to ensure that measurements and test results are accurate and reliable. The CMA also plays a role in promoting and developing new measurement technologies and methods. In addition, the CMA publishes frameworks for the standardization of measurements and test procedures.
All test labs in China that are accredited for product tests for CCC certification must be accredited by CMA.
Certification for measuring instruments is divided into a provincial or national level. Depending on the desired certification, different institutions are responsible and certain regulations must be observed. At the national level, the “General Administration of Quality Supervision, Inspection and Quarantine of the People’s Republic of China”, or AQSIQ for short, supervises all institutions involved. An organization that has received the CMA certificate may use this on the certificates and reports issued and refer to the corresponding references.
