Which statement about API 578 material verification program is true?

• A. It covers only pressure containing components
• B. It covers all piping components
• C. Only non-pressure components are included
• D. Only seals and gaskets are specified

Answer: (A)

The essential point is that API 578’s Material Verification Program focuses on the materials used in the pressure-retaining parts of a piping system. It applies to pressure-containing components—pipes, fittings, flanges, valves, and similar items where the material identity and properties directly affect the ability to contain pressure. It ensures those materials are the ones specified and are traceable through proper documentation (like mill test reports and heat numbers). It does not extend to non-pressure components or to seals and gaskets, which are not part of the pressure boundary or are treated separately. Therefore, the statement that it covers only pressure-containing components is the correct description of the program’s scope.
