For high-risk piping systems with likely material mixups, what percentage of material examination is required?

• A. 50 percent
• B. 100 percent
• C. 75 percent
• D. 25 percent

Answer: (B)

In high-risk piping systems where material mixups are likely, every component must undergo material examination. This full verification ensures the actual material, grade, and heat number match the design and specifications, preventing mismatches that could compromise strength, corrosion resistance, or compatibility with other parts. Relying on partial sampling can miss mislabeled or substituted items, which is unacceptable when the consequences of using the wrong material are so serious. Performing material identification on 100 percent of components provides complete traceability to purchase orders and material certifications, and it aligns with best practices for safe, code-compliant operation.
