CMA certification is a certification body authorized by China National Certification and Accreditation Administration (CNCA), which comprehensively reviews the measuring equipment, testing methods and testing environment of testing laboratories to ensure that they meet the relevant national standards and technical specifications. A CMA-certified laboratory can use the CMA mark in its report, indicating that the laboratory has the corresponding measurement certification level and qualification.
CNAS is an important part of China's national accreditation system for conformity assessment, and it is a certification body headed by China's National Certification and Accreditation Administration (CNCA). The conformity assessment process of CNAS accredited testing laboratories includes the comprehensive assessment of quality management system, technical ability and personnel quality. A laboratory accredited by CNAS can use the CNAS mark in its report, indicating that the laboratory has the corresponding conformity assessment ability and qualification.
CMA and CNAS certification are very important for testing laboratories, which represent the laboratory's ability and level in metrology certification and conformity assessment. These certifications can help laboratories improve the accuracy and reliability of their test results, thus better serving customers and society. At the same time, these certifications are also important conditions for the laboratory to gain national and international recognition, which is of great significance to its business expansion and development.
Are two different certification marks, which are different in nature, application conditions, scope of application and authority.
First, the nature is different.
CMA is certified by a third-party testing organization, similar to an intermediary organization, and is generally only responsible for the test results of samples. CMA is a third-party fair and just certification, not a legally recognized certification body. CNAS is the abbreviation of China National Accreditation Committee for Conformity Assessment. It is a national accreditation body authorized by the National Certification and Accreditation Administration, and is responsible for the accreditation of certification bodies, laboratories and inspection institutions.
Second, the application conditions are different.
CMA has relatively low application requirements, and generally has independent legal personality and fixed office space. The registered capital needs to reach a certain scale, and inspection and testing institutions with corresponding professional and technical personnel can apply. The application conditions of CNAS are relatively high. In addition to certain hardware conditions (such as laboratory space and equipment), software conditions (such as management system documents and personnel qualifications) need to be met, and strict audit and evaluation procedures are required.
Third, the scope of application is different
CMA is mainly suitable for third-party testing institutions, and its testing results are mainly used for customers to judge product quality. CNAS is applicable to all organizations or institutions engaged in laboratory activities, including internal laboratories, third-party testing institutions and scientific research institutes.
Fourth, the authority is different.
CMA certification body is usually an independent legal person approved by the metrological administrative department of the people's government at or above the provincial level, and its certification results are valid within the corresponding scope above the provincial level. CNAS is a national accreditation body recognized and authorized by CNCA, and its certification results are valid nationwide. These certification bodies have professional knowledge and experience in their respective fields, and provide comprehensive, efficient and reliable certification services for various institutions.
To sum up, CMA and CNAS are different in nature, applicable conditions, applicable scope and authority. If you need to test products or learn more about CMA and CNAS, please check the official website or consult a professional.
