AS9100 Details
What It Is
AS9100D:2016 is the international certification standard for quality management systems (QMS) in aviation, space, and defense. It extends ISO 9001:2015 with over 100 aerospace-specific requirements, using a process-based, risk-oriented approach across 10 clauses.
Key Components
- Core pillars: context, leadership, planning, support, operation, evaluation, improvement.
- Aerospace additions: configuration management (8.1.2), product safety (8.1.3), counterfeit prevention (8.1.4), operational risks (8.1.1), human factors.
- Built on Annex SL structure; certified via accredited third-party audits (Stage 1/2, surveillance).
Why Organizations Use It
- Enables market access as OEM prerequisite.
- Reduces defects, improves delivery, manages supply chain risks.
- Enhances safety, traceability, counterfeit avoidance.
- Builds stakeholder trust via OASIS visibility.
Implementation Overview
- Phased: gap analysis, process design, training, internal audits, certification (6-18 months).
- Applies to designers, manufacturers, suppliers; global scope.
- Evidence-driven audits emphasize operational effectiveness.
EN 1090 Details
What It Is
EN 1090 is the European harmonized standard family (EN 1090-1, -2, -3) governing execution and conformity assessment of structural steel and aluminium components/kits for construction works. Under the CPR, it enables CE marking via a risk-based approach through Execution Classes (EXC1-4), scaling requirements for fabrication, welding, tolerances, and inspection.
Key Components
- **EN 1090-1FPC certification, AVCP, DoP issuance
- **EN 1090-2/-3Technical rules for steel/aluminium execution
- **Core pillarsMaterial traceability, welding (ISO 3834), NDT, tolerances
- Notified body certification with ongoing surveillance
Why Organizations Use It
- Mandatory for EU market access and CE marking
- Mitigates liability, ensures safety via risk scaling
- Builds trust, reduces rework, enables high-risk projects
- Competitive edge in tenders, supply chains
Implementation Overview
Phased: gap analysis, FPC build, personnel quals, NB audit. Applies to fabricators globally targeting EU; 6-12 months typical, certified FPC essential. (178 words)
