Report: ASME Section V — Article 9 (Non-Destructive Examination — Radiographic Film Interpretation)

Scope and purpose

Article 9 of ASME Section V provides rules and guidance for the interpretation of radiographic film used in nondestructive examination (NDE) of welded and cast pressure-retaining components. Its purpose is to define acceptance criteria, image evaluation procedures, and reporting conventions so radiographic results are applied consistently for pressure vessel and piping code compliance.

Translucent: Shining light through materials like fiberglass-reinforced plastics to find internal flaws. asme section v article 9

Essential Variables: Changes in these (e.g., switching from direct to remote viewing) require the procedure to be requalified by demonstration. Report: ASME Section V — Article 9 (Non-Destructive

• Unaided or corrected vision (Jaeger J2 at 12 inches or equivalent)
• Color differentiation sufficient to distinguish contrast between indication and background
• Annual vision examination (near vision, far vision, color)

• Verification of the weld joint configuration and location
• Detection and characterization of defects
• Comparison of the radiographs to the acceptance criteria

Practical Application (Why it matters)

In pressure vessel construction, Visual Examination is typically required for: Unaided or corrected vision (Jaeger J2 at 12
