CNAS

CNAS laboratory accreditation is the National Accreditation Commission for Conformity Assessment in China.

The China National Accreditation Service for Conformity Assessment (CNAS) is a national accreditation institution established and authorized by the National Certification and Accreditation Administration Commission in accordance with the provisions of the Certification and Accreditation Regulations of the People's Republic of China. It is responsible for the recognition of certification bodies, laboratories, and inspection institutions.

CNAS was formed by the merger of the former Chinese certification body, the National Accreditation Service (CNAB), and the former China National Accreditation Service for Laboratories (CNAL). CNAS evaluates and supervises the management and activities of conformity assessment agencies (such as certification agencies, laboratories, inspection agencies), confirms their ability to carry out corresponding conformity assessment activities (such as certification, testing and calibration, inspection, etc.), confirms the authority of their conformity assessment activities, and plays a recognized and binding role.
