ASME Section II Part D provides information on which topic?

• A. Material specifications
• B. Design data
• C. Welding procedures
• D. Testing requirements

Answer: (A)

Section II Part D contains the material properties data for the wide range of materials used in pressure vessels and piping. This collection of mechanical and physical properties—such as tensile strength, yield strength, elongation, toughness, and other performance data—provides the authoritative information you need to specify materials properly. When you write a material specification, you must ensure the material will meet the required properties under the service conditions, and the data in Part D is exactly what you reference to verify those requirements. In short, Part D is the go-to source for the information that underpins material specifications, rather than detailing welding procedures, design data, or testing requirements, which are covered in other parts and sections of the code.
