This guideline, "Guidelines for Accreditation of Testing and Calibration Laboratories", is equivalent to ISO / IEC 17025: 2005.
This standard contains all the requirements that testing and calibration laboratories must meet in order to prove that they operate according to the management system, have technical capabilities, and can provide correct technical results. At the same time, this standard contains all the requirements of ISO 9001 related to the testing and calibration services covered by the laboratory management system. Therefore, testing and calibration laboratories that comply with this standard are also operated in accordance with ISO 9001.
The laboratory quality management system meets the requirements of ISO 9001, and does not prove that the laboratory has the ability to produce technically valid data and results; the laboratory quality management system conforms to this standard, nor does it mean that its operations meet all the requirements of ISO 9001.
China National Accreditation Service for Conformity Assessment (English abbreviation: CNAS) uses this standard as a basis for accreditation of testing and calibration laboratories. In order to support accreditation activities in specific fields, CNAS has also formulated a series of field-specific application notes based on the professional characteristics of different fields to provide necessary supplementary explanations and explanations for the general requirements of this Code, but does not increase or decrease the requirements of this Code.
Laboratories applying for CNAS accreditation should also meet the guidelines and application instructions in the corresponding fields.
