The API 578 material verification program covers which components?

• A. Only pressure containing components
• B. All piping components
• C. Only non-pressure components
• D. Only valves

Answer: (A)

API 578 Material Verification concentrates on the materials used to form the pressure boundary. The program ensures that the chemistry, heat treatment, and traceability of those materials meet design and code requirements because any mismatch in material properties can lead to failure under pressure. Therefore, its scope is the components that actually contain or are intended to contain pressure—piping, fittings, flanges, valves, and other equipment that form the pressure boundary. It does not apply to parts that don’t carry pressure or to non-pressure components.
