Non-destructive testing methods are standardized in which ASME Section?

• A. ASME Section II
• B. ASME Section V
• C. ASME Section IV
• D. ASME B31.5

Answer: (B)

Nondestructive testing methods are standardized in ASME Section V. This section is dedicated to nondestructive examination (NDE) and specifies how NDE is to be performed, which methods are allowed (such as radiography, ultrasonics, magnetic particle, liquid penetrant, and visual inspection), the required procedures, acceptance criteria, and the qualification of NDE personnel. Keeping NDE in its own section ensures that the integrity checks on components can be done consistently without tying them to material properties or construction rules. The other sections focus on different topics: Section II covers materials and their properties, Section IV covers the construction rules for boilers and vessels, and B31.5 addresses piping design, fabrication, and testing rather than standardizing NDE methods.
