Which organization standardized specifications and testing methods for metals?

• A. ASTM
• B. ISO
• C. ANSI
• D. AWS

Answer: (A)

Standards bodies that publish uniform specifications and testing methods for metals ensure that metal products and procedures are defined clearly so everyone can design, manufacture, and inspect consistently. ASTM International is the organization that specializes in developing and publishing a broad set of metal standards and testing procedures used worldwide. Its scope includes material composition limits, mechanical property requirements, and standardized test methods (for example, common tensile testing and hardness testing) that apply to a wide range of metals and alloys. This breadth and focus on metals make ASTM the best fit for standardized specifications and testing methods for metals. ISO also issues metal standards and has international reach, ANSI is mainly an accrediting and coordinating body, and AWS concentrates on welding-specific standards rather than general metal specifications.
