Testing & Calibration Laboratories
General requirements for the competence of testing and calibration laboratories. Establishes requirements for laboratories demonstrating competence and generating valid results, forming the basis for laboratory accreditation.
ISO/IEC 17025 is the international standard for the competence of testing and calibration laboratories, forming the basis for laboratory accreditation by bodies such as UKAS, A2LA, and ILAC signatories. It specifies requirements for technical competence, valid results, and impartial operation.
The 2017 revision introduced a process approach, added risk-based thinking, and strengthened requirements for measurement uncertainty, method validation, and the validity of results. It applies to laboratories conducting chemical analysis, physical testing, biological testing, calibration, and non-destructive testing.
ACI-certified ISO/IEC 17025 auditors assess laboratory management systems and technical operations, evaluating method validation, measurement uncertainty, and the adequacy of quality assurance programmes for test and calibration results.
