Elements and Performance Criteria

1. Assess requirements for NDT
   • The inspection area is assessed for testing and all possible failure sites identified using metallurgical analysis
   • Information relevant to test development is collected from available sources using accepted techniques
   • Information is analysed and interpreted
   • Test requirements are determined
2. Evaluate NDT techniques and procedures
   • Test methods, techniques and procedures for specific NDT tasks are specified
   • Applicable codes, standards, specifications and procedures are interpreted
   • Test procedures are developed in accordance with established techniques and metallurgical principles
3. Validate/confirm NDT tasks
   • General and specific test procedures are validated in accordance with established techniques
   • Inspection results are interpreted in accordance with existing codes, standards and specifications
4. Evaluate NDT test procedures
   • Procedures are evaluated for effectiveness
   • Evaluation results are documented and reported in accordance with standard enterprise procedures
   • Changes/amendments to NDT procedures are made and distributed in accordance with standard enterprise procedures
