ISO 17025, PearL’s quality standard

PearL : système qualité ISO 17025



ISO 17025 is an international standard specifying the general requirements in regards with the calibration and testing laboratories skills.


This norm, regarding the analysis and testing laboratories, is the frame of reference used during the accreditation audits. The quality system of the ISO 17025 accredited laboratories is based on the ISO 9001:2000 norms.


In France, COFRAC gives accreditations on the demand from the testing and analysis laboratories according to this norm, with extended requirements defined in the LAB REF 02 Document.


This accreditation is a strong recognition of the technical skills.
