ISO 17025 Details
What It Is
ISO/IEC 17025:2017 is the international standard specifying general requirements for the competence, impartiality, and consistent operation of testing and calibration laboratories. It applies a risk-based, performance-oriented approach tying management controls to technical validity of results, covering testing, calibration, and sampling.
Key Components
- Eight main clauses: general (impartiality/confidentiality), structural, resource (personnel, facilities, equipment, traceability), process (methods, validation, uncertainty, reporting), and management system requirements.
- **Core principlesrisk-based thinking, metrological traceability, measurement uncertainty, proficiency testing.
- Compliance via accreditation by ILAC-recognized bodies attesting scope-specific competence (Option A standalone or B with ISO 9001).
Why Organizations Use It
- Enables market access, regulatory acceptance, and international result recognition.
- Mitigates risks from invalid results impacting safety, compliance, finance.
- Builds stakeholder trust, differentiates competitively, reduces rework via efficient processes.
Implementation Overview
Phased PDCA: gap analysis, documentation, training, validation, audits. Suits labs of all sizes/industries globally; requires witnessed technical assessments for accreditation.
IATF 16949 Details
