ISO/IEC 17025 Accreditation (Testing & Calibration Laboratories)
A practical guide to competence, method control, traceability, and audit-ready results — built for laboratory confidence.
What ISO/IEC 17025 is (in operational terms)
ISO/IEC 17025 is the core competence standard for testing and calibration laboratories. Audits focus on technical evidence: method validity, traceability, equipment control, competence, and whether reported results are reliable and repeatable.
Typical scope choices that affect the audit
- Which tests/calibrations and methods are included in the scope.
- Sample handling boundaries (collection, transport, storage) and responsibilities.
- Equipment ranges and reference standards in scope.
- Subcontracted tests and how you control them.
Key ISO/IEC 17025 expectations
- Method validity: validation/verification and ongoing performance checks.
- Measurement traceability: references, calibration chains, and evidence.
- Uncertainty & decision rules: where applicable, documented and applied.
- Equipment control: calibration, maintenance, and suitability.
- Results reporting: complete, controlled reports with retained records.
