NADCAP

What is NADCAP?

NADCAP (National Aerospace and Defense Contractors Accreditation Program) is a globally recognized accreditation system for special processes in the aerospace industry. The goal is to ensure standardized and quality-assured manufacturing and testing processes.

Hardness Testing under NADCAP

Hardness testing is part of the NADCAP category "Materials Testing Laboratories (MTL)".

Strict requirements apply to personnel, procedures, equipment, and documentation.

Requirements for NADCAP-Compliant Hardness Testing

• Standards-Compliant Procedures according to ASTM E18, ASTM E384, ISO 6507, etc.
• Calibrated and Traceable Equipment: 
  • Regular maintenance and calibration of testing machines
  • Full traceability of calibration records

• Qualified Testing Personnel:
  • Verified training and ongoing competence assessments

• Complete Documentation & Traceability: detailed records of test parameters, results, and conditions
• Reproducible Evaluations - especially relevant for image-based microhardness testing
• Quality Assurance Measures:  Internal round-robin tests, repeatability checks, corrective actions
