EN 9100 Calibration Requirements
EN 9100 is the European aerospace quality management standard published by CEN (European Committee for Standardization) and adopted nationally as DIN EN 9100 (Germany), BS EN 9100 (UK), NF EN 9100 (France), and UNI EN 9100 (Italy). EN 9100 is technically identical to AS9100 (Americas) and JISQ 9100 (Asia-Pacific) — all three are regional publications of the IAQG 9100-series. Section 7.1.5 governs calibration: every measuring instrument must be calibrated at defined intervals against standards traceable to a European national metrology institute (PTB, NPL, LNE, INRIM, BEV, VTT MIKES, RISE, or equivalent). Certification is mandatory for Tier 1, 2, and 3 suppliers to Airbus, Safran, Rolls-Royce, Leonardo, Dassault, MTU, Thales, and most EU aerospace primes.
Section 7.1.5 of EN 9100:2018 — the European publication of the IAQG 9100:2016 parent standard — requires that monitoring and measuring resources be calibrated or verified at specified intervals against measurement standards traceable to international (BIPM) or national (PTB, NPL, LNE, INRIM, and the other EU NMIs) standards. Where no such standards exist, the basis for calibration must be documented. Equipment must be identified to determine calibration status, protected from adjustments that would invalidate calibration, and subjected to reverse-traceability evaluation when found out-of-tolerance. Calibration records must include measurement uncertainty values reported per ISO/IEC Guide 98-3 (GUM). Certification bodies accredited to EN ISO/IEC 17011 (accreditation bodies) certify EN 9100 compliance via auditors competent under EN 9101 (audit requirements).
EN 9100 is republished by national standards bodies as DIN EN 9100 in Germany (by DIN, the German Institute for Standardization), BS EN 9100 in the UK (by BSI), NF EN 9100 in France (by AFNOR), and UNI EN 9100 in Italy (by UNI). The technical content is identical across all publications; the accreditation body and certification body landscape varies. Germany uses DAkkS-accredited certification bodies; the UK uses UKAS; France uses COFRAC; Italy uses Accredia; other EU countries have equivalent national accreditation authorities. Suppliers certify to one national publication — typically the one their primary certification body is accredited under — and that certificate is mutually recognized across the EU and via the IAQG OASIS database globally.
All three standards are regional publications of the same IAQG 9100 parent. AS9100 Rev D, EN 9100:2018, and JISQ 9100:2016 contain the same numbered clauses and the same technical requirements. Differences are administrative: the issuing body (SAE, CEN, JSA), the audit body network, and the cost of certification in local currency. Mutual recognition is automatic for suppliers certified to any one of the three via IAQG OASIS. The practical choice of which standard to certify to is determined by your primary prime contractor (Boeing or Northrop typically expects AS9100; Airbus or Safran expects EN 9100; Mitsubishi Heavy Industries or Kawasaki expects JISQ 9100) and by which certification body's accreditation your auditor carries.
Airbus suppliers operating under PSQN (Supplier Quality Notices) must demonstrate EN 9100 certification with calibration records that support First Article Inspection (FAI) per EN 9102 — the European publication of the aerospace FAI standard. Safran requires suppliers certified to EN 9100 to maintain EN ISO/IEC 17025-traceable calibration for all dimensional measurement on flight-critical components. Rolls-Royce's SABRE supplier quality programme requires calibration intervals justified by drift analysis, commonly using ILAC G24 staircase methodology. Leonardo's supplier quality assurance requirements mirror these expectations. In all cases, the reverse-traceability investigation triggered by out-of-tolerance findings is a hot-button audit item — auditors look for documented impact assessments on every product measured with a suspect instrument since its last verified calibration.
CalibrationOS is built around the IAQG 9100-series calibration requirements, which means EN 9100 support is the same capability stack that serves AS9100 and JISQ 9100 customers. Key features for EN 9100 suppliers: GUM-compliant measurement uncertainty budgets with expanded uncertainty (k=2) reported on every certificate; automated ILAC G24 interval optimization from pass/fail history; reverse-traceability report showing every product measured with a given instrument since its last valid calibration; certificate templates aligned with EN 9102 First Article Inspection and Airbus PSQN requirements; multi-currency cost tracking in Euros; traceability chain documentation naming the European NMI (PTB, NPL, LNE, etc.) used by your calibration laboratory. The platform generates audit evidence suitable for DAkkS, UKAS, COFRAC, Accredia, and other EU accreditation body assessments.
EN 9100 is the European publication of the IAQG 9100-series aerospace quality management standard, published by CEN. Tier 1, 2, and 3 suppliers to European aerospace primes — Airbus, Safran, Rolls-Royce, Leonardo, Dassault, MTU, Thales, Liebherr, Saab, and their sub-contractors — typically must be certified to EN 9100 or its national equivalent (DIN EN 9100, BS EN 9100, NF EN 9100, UNI EN 9100) to supply flight hardware.
Technically yes. EN 9100 (Europe), AS9100 (Americas), and JISQ 9100 (Asia-Pacific) are regional publications of the same IAQG 9100 parent standard with identical numbered clauses and requirements. Administrative differences exist: issuing body (CEN vs SAE vs JSA), accreditation bodies, and local-currency cost of certification. Certification to any one of the three is recognized globally via the IAQG OASIS database.
DIN EN 9100 is the German national publication of EN 9100 — the exact same standard, republished by DIN (the German Institute for Standardization). Similarly, BS EN 9100 (UK), NF EN 9100 (France), and UNI EN 9100 (Italy) are national publications. Suppliers certify once to whichever national publication their certification body is accredited under, and that certificate is accepted across the EU.
Germany: DAkkS. United Kingdom: UKAS. France: COFRAC. Italy: Accredia. Spain: ENAC. Netherlands: RvA. Sweden: SWEDAC. Austria: Akkreditierung Austria. Each EU member state has a national accreditation body that accredits certification bodies to issue EN 9100 certificates. Certification bodies commonly used include BSI, DNV, LRQA, Bureau Veritas, TÜV SÜD, TÜV Rheinland, SGS, and AFNOR Certification.
EN 9100 auditors request calibration certificates with expanded measurement uncertainty (k=2) reported per ISO/IEC Guide 98-3 (GUM), traceability chains to a national metrology institute (PTB, NPL, LNE, INRIM, or equivalent), recall schedules with interval justification (ILAC G24 staircase analysis is widely accepted), reverse-traceability records for out-of-tolerance events, and evidence of calibration status identification on every instrument. First Article Inspection (EN 9102) records must reference the specific calibration certificates for each measuring device used.
Yes — CalibrationOS is IAQG 9100-series aligned by design, which means EN 9100 support is the same feature stack that serves AS9100 and JISQ 9100 customers. The platform generates GUM-compliant uncertainty budgets, automates ILAC G24 interval optimization, provides instant reverse-traceability reports for OOT events, supports EN 9102 FAI documentation, and tracks costs in Euros. Certificate templates are aligned to DAkkS / UKAS / COFRAC / Accredia audit expectations.
