FAQ
What is CNAS?
CNAS and International Recognition
CNAS, short for China National Accreditation Service for Conformity Assessment, is a member of the International Laboratory Accreditation Cooperation (ILAC), a global network of accreditation bodies. ILAC comprises over 100 member organizations from around the world, such as DAkkS (Germany), A2LA (US), UKAS (UK), JAB (Japan), among others.
These organizations, along with CNAS, contribute to mutual recognition agreements (MRAs) that promote the global acceptance of conformity assessments through accreditation. This means, products and services certified by CNAS are recognized and accepted in other member organizations.
CNAS: Ensuring Quality and Compliance
CNAS plays a vital role in China’s quality assurance and conformity assessment framework. It is responsible for accrediting various conformity assessment bodies, including laboratories, inspection bodies, and certification bodies.
CNAS employs a rigorous evaluation system to ensure that these bodies meet specific quality and management standards. This process involves comprehensive assessments and audits to verify compliance with international norms. Only CNAS-accredited bodies are authorized to carry out critical assessments that impact public health and safety.
What is ISO 17025? Why does it matter?
ISO 17025 is an international standard specifically designed for testing and calibration laboratories. It sets the general requirements for the competence of these laboratories, ensuring that they operate consistently and generate reliable results.
As a member of ILAC, CNAS adopts ISO 17025 as a benchmark to assess and accredit testing and calibration laboratories. Obtaining CNAS accreditation signifies that a laboratory complies with ISO 17025 standards and can perform reliable testing and calibration. This accreditation allows CNAS-accredited laboratories to participate in internationally recognized MRAs, ensuring that their test and calibration results are accepted globally.
What is VDI/VDE 2634 and why do you need it?
VDI/VDE 2634 is a set of international standards issued by the Association of German Engineers (VDI) and the Association for Electrical, Electronic & Information Technologies (VDE). These standards are specifically designed for the calibration of optical 3D measuring systems. VDI/VDE 2634 Part 2 covers single-view systems; while Part 3 addresses multi-view systems. The standards ensure the accuracy and reliability of 3D measurements, providing guidelines for calibration procedures and performance verification.
Certificates based on VDI/VDE standards are highly regarded in the field of engineering and technology, providing rigorous guidelines and precision for various technical aspects.
