CNAS Laboratory Accreditation Standard 17025 refers to the guiding standard for laboratory competence accreditation issued by the China National Accreditation Service for Conformity Assessment (CNAS).
The standard requires laboratories to be able to meet and implement a series of stringent requirements and processes to ensure the accuracy and reliability of their tests and calibrations.
Laboratory accreditation standard 17025 requires that laboratories must have a complete quality management system and be able to operate in accordance with international standards.
This includes requirements for the qualifications of laboratory personnel, equipment and environment, and requirements for the management of laboratory records and documentation.
This accreditation standard requires laboratories to conduct both internal and external quality control.
Internal quality control refers to the laboratory's assurance of the accuracy of test results by establishing the use of standard and analogous substances, as well as conducting repeatability testing and uncertainty assessments.
External quality control is when a laboratory participates in a comparative test organized by a nationally or internationally recognized institution to assess whether the test results of the laboratory are consistent with those of other accredited laboratories.
CNAS Laboratory Accreditation Standard 17025 requires laboratories to establish and maintain a traceable measurement system.
Traceability means that laboratories must be able to demonstrate that their measurements have been compared to international or national legal units, thus ensuring the reliability and accuracy of test results.
Accreditation Standard 17025 also requires laboratories to establish and maintain a robust system of documentation and records.
This includes the preparation and implementation of laboratory procedures, test methods, and standard operating procedures.
Laboratories also need to document and save test results so that any potential issues can be reviewed and tracked.
The standard also requires laboratories to develop and implement procedures for handling accidents and non-conforming articles to ensure that corrective and preventive measures can be taken in a timely manner when problems arise.
CNAS Laboratory Accreditation Standard 17025 provides a set of strict requirements and procedures for product certification and testing.
After completing the accreditation, the laboratory can provide customers with accurate and reliable test data to support product quality.
By complying with the requirements of the standard, laboratories are able to ensure the traceability, accuracy and reliability of their tests, improving the competitiveness and market reputation of their products.
