Which ASME document would you consult for material specifications of pressure vessel components?

• A. ASME Section II Part D
• B. ASME Section V
• C. ASME B16.34
• D. ASME B16.9

Answer: (A)

Material data and the specific properties materials must meet are found in ASME BPVC Section II, which covers the material specifications used for pressure vessels. Within Section II, Part D gathers the properties data for a wide range of materials—tensile strength, yield strength, elongation, impact toughness, hardness, and temperature limits—so you can verify that a candidate material satisfies the design requirements and service conditions. This makes it the go-to reference when selecting and qualifying materials for vessel components. The other references deal with different topics: Section V covers nondestructive examination, while B16.34 and B16.9 are standards for valves, fittings, and other components, not for material property data. Therefore, Section II Part D is the appropriate document for material specifications.
