Which professional organization is known for setting codes and standards for mechanical devices in the U.S.?

The American Society of Mechanical Engineers (ASME) is recognized for setting codes and standards that govern the design, manufacturing, and testing of mechanical devices in the U.S. Founded in 1880, ASME has played a significant role in shaping engineering standards, ensuring safety, reliability, and quality in the mechanical engineering field. Their standards are widely adopted in industries such as power generation, aerospace, and manufacturing, influencing both national and international practices.

While other organizations listed do have important functions, they serve different domains. For instance, IEEE primarily focuses on electrical and electronic engineering, ANSI is involved in the accreditation of standards but does not develop them directly, and ISO is an international standard organization that develops a wide range of standards but is not specific to mechanical devices in the U.S. ASME’s specific focus on mechanical engineering standards makes it the correct choice in this context.
