BSCI certification is an abbreviation of BusinessSocialComplianceInitiative, and Chinese is called business social standard certification. BSCI is an organization that advocates the business community to abide by social responsibility. At the same time, it is a non-profit organization.
CMA, the name is \"China Metrology Accreditation\", the abbreviation of \"China Metrology Accreditation\" in English. According to the provisions of Article 22 of the Metrology Law of the People’s Republic of China: “The product quality inspection agency that provides notarized data to the society must be evaluated by the metrological administrative department of the people’s government at or above the provincial level for the capability and reliability of metrological verification and testing. Qualified.\"
Laboratory accreditation is a third-party certification that CNAS has the ability to perform specific testing and calibration work for testing and calibration laboratories.
