ISO 17025 vs EN 1090
ISO 17025
International standard for competence of testing and calibration laboratories
EN 1090
EU standard for steel and aluminium structural execution
Quick Verdict
ISO 17025 accredits testing labs for competence and impartiality globally, while EN 1090 mandates CE marking for EU structural steel/aluminium via Factory Production Control. Labs seek trust in results; fabricators ensure market access and legal compliance.

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 linking management systems to technical validity of results, covering testing, calibration, and sampling activities.
Key Components
- Organized into **8 elementsscope, general (impartiality/confidentiality), structural, resource, process, and management system requirements.
- Emphasizes personnel competence, metrological traceability, measurement uncertainty, method validation, and proficiency testing.
- Built on risk-based thinking; offers Option A (standalone) or Option B (ISO 9001 integration) for management systems.
- Leads to accreditation by ILAC-recognized bodies, attesting technical competence within defined scopes.
Why Organizations Use It
- Ensures global acceptance of results, enabling market access and regulatory compliance.
- Mitigates risks of invalid data impacting safety, finance, and reputation.
- Provides competitive edge through demonstrated credibility and efficiency gains.
- Builds stakeholder trust via impartiality safeguards and traceable outputs.
Implementation Overview
- Phased PDCA approach: gap analysis, documentation, training, validation, audits.
- Suited for labs across industries; requires technical investments in calibration, PT.
- Involves accreditation assessments with witnessed activities and ongoing surveillance.
EN 1090 Details
What It Is
EN 1090 is a harmonized European standard family (EN 1090-1, -2, -3) under the Construction Products Regulation (CPR). It governs execution and conformity assessment of structural steel and aluminium components/kits for construction works. Primary purpose: ensure controlled fabrication, welding, and performance declaration via CE marking. Adopts risk-based scaling through Execution Classes (EXC1–EXC4).
Key Components
- **EN 1090-1Conformity assessment, Factory Production Control (FPC) certification, Declaration of Performance (DoP).
- **EN 1090-2/-3Technical rules for steel/aluminium (materials, welding, tolerances, corrosion protection, NDT).
- Core principles: traceability, welding per ISO 3834, risk-proportional controls.
- Third-party Notified Body certification with ongoing surveillance.
Why Organizations Use It
Mandatory for EU market access; enables CE marking, reduces liability, ensures stakeholder trust. Strategic benefits: risk mitigation, quality consistency, competitive bidding advantage.
Implementation Overview
Phased: gap analysis, FPC build, welding qualification, NB certification (3-12 months). Targets fabricators in construction; requires personnel training, process integration, audits.
