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 performance-based, risk-based approach linking management systems to technical validity of results, covering testing, calibration, and sampling.
Key Components
- Eight main clauses: general (impartiality/confidentiality), structural, resource, process, and management system requirements.
- Core elements include metrological traceability, measurement uncertainty, method validation/verification, personnel competence, and proficiency testing.
- Built on risk-based thinking; management system via Option A (standalone) or Option B (ISO 9001-aligned).
- Leads to accreditation by bodies like ILAC signatories, attesting technical scope-specific competence.
Why Organizations Use It
- Enables market access, regulatory acceptance, and international result recognition.
- Mitigates risks of invalid results impacting safety, compliance, finance.
- Builds stakeholder trust through demonstrated impartiality and traceability.
- Provides competitive edge via credible, defensible outputs.
Implementation Overview
- Phased PDCA: gap analysis, documentation, technical validation, audits, accreditation assessment.
- Suits labs of all sizes in regulated industries globally.
- Involves training, equipment calibration, LIMS controls; requires ongoing surveillance audits.
AS9120B Details
What It Is
AS9120B is the IAQG quality management system standard for aerospace distributors, built on ISO 9001:2015's 10-clause structure. It targets organizations procuring, storing, splitting, and reselling parts without alteration, emphasizing risk-based thinking to mitigate supply chain risks like traceability loss and counterfeits.
Key Components
- Over 100 aerospace-specific requirements beyond ISO 9001.
- Core areas: context analysis, leadership, planning, support, operations (traceability, counterfeit prevention, external providers), performance evaluation, improvement.
- Built on PDCA cycle; requires documented information, not full procedures.
- Certification via accredited bodies, OASIS listing.
Why Organizations Use It
- Commercial necessity for OEM/Tier 1 supply chains.
- Reduces risks of nonconformities, counterfeits, recalls.
- Enhances market access, customer trust, efficiency.
- Builds resilience via KPIs, audits, continual improvement.
Implementation Overview
- Phased: gap analysis, process design, training, audits (6-12 months).
- Applies to aviation/space/defense distributors globally.
- Involves cross-functional teams, internal audits, Stage 1/2 certification.
