AS9100 Calibration Requirements
AS9100 Rev D is the internationally recognized quality management standard for the aerospace industry, building on ISO 9001 with additional requirements for product safety, reliability, and configuration management. Calibration management is critical under AS9100 because measurement uncertainty directly impacts flight-critical hardware acceptance decisions. Organizations must demonstrate traceability to national or international standards for every measuring device used in production and inspection.
Section 7.1.5 of AS9100 Rev D requires that monitoring and measuring resources be calibrated or verified at specified intervals against measurement standards traceable to international or national standards. When no such standards exist, the basis for calibration must be documented and retained. Equipment must be identified to determine calibration status, and organizations must safeguard equipment from adjustments, damage, or deterioration that would invalidate the calibration status. Records of calibration results, including measurement uncertainty data, must be maintained.
Beyond ISO 9001 baseline requirements, AS9100 mandates risk-based thinking applied to calibration intervals, requiring organizations to adjust recall schedules based on historical reliability data and equipment criticality. First Article Inspection (FAI) under AS9102 requires that all measurement equipment used during FAI be calibrated and traceable. Nonconforming product reviews must evaluate whether out-of-tolerance instruments may have affected prior acceptance decisions, triggering product recalls or re-inspection campaigns.
CalibrationOS automates recall scheduling with risk-based interval adjustment algorithms that analyze historical pass/fail data to optimize calibration frequencies. The platform generates AS9100-compliant calibration certificates with measurement uncertainty statements and full traceability chains. Automated out-of-tolerance impact assessments identify all products measured with a nonconforming instrument, enabling rapid containment and disposition decisions required by aerospace registrars.
AS9100 audits by registrars such as SAI Global, BSI, or DNV require immediate access to calibration records, certificates, and traceability documentation. CalibrationOS maintains a permanent audit trail of all calibration events, adjustments, and status changes. Dashboard views provide real-time compliance metrics including overdue calibration rates, out-of-tolerance trends, and measurement system capability indices that auditors commonly request during surveillance audits.
AS9100 Rev D Section 7.1.5 requires calibration or verification at defined intervals with traceability to national or international measurement standards. Organizations must maintain records of calibration results including measurement uncertainty, identify equipment calibration status, and evaluate the impact of out-of-tolerance findings on previously accepted product.
AS9100 adds aerospace-specific requirements including risk-based calibration interval management, mandatory measurement uncertainty reporting, and out-of-tolerance impact assessments that may trigger product recalls. It also requires calibration records to support First Article Inspection under AS9102 and configuration management of measurement equipment.
Registrar auditors typically request calibration certificates with measurement uncertainty statements, traceability chains to NIST or equivalent standards, recall schedules with justification for intervals, and evidence of out-of-tolerance impact assessments. They also verify that calibration status identification is visible on all measuring equipment.
CalibrationOS automates recall scheduling with risk-based interval optimization, generates compliant calibration certificates, and provides instant out-of-tolerance impact analysis across all affected work orders. The platform maintains a complete audit trail and produces dashboard metrics that satisfy registrar surveillance audit requirements.
Yes, CalibrationOS calculates and records measurement uncertainty for each calibration event using GUM-compliant methods. Uncertainty budgets are stored alongside calibration certificates and can be compared against measurement capability requirements to ensure guardbanding ratios meet aerospace acceptance criteria.
CalibrationOS automates tracking, audit trails, and due date management to keep you AS9100-ready.
