Where is radiographic examination required?

• A. Section II
• B. Section V
• C. Section VIII Division 1
• D. B31.3

Answer: (B)

Radiographic examination is a nondestructive testing method, and the ASME code section that specifies how this NDT method is applied, who is qualified, and what constitutes acceptable radiographs is Section V. That section lays out the methods, equipment, personnel qualifications, and acceptance criteria for radiography (and other NDT methods) used during fabrication and inspection. The other sections have different focuses—Section II covers material properties, Section VIII Division 1 covers design and construction, and B31.3 governs piping design and fabrication with NDE requirements that ultimately rely on Section V for the radiography details. So radiographic examination is required by Section V.
