Identify the organization that represents standards for mechanical engineering.

The organization that represents standards for mechanical engineering is the American Society of Mechanical Engineers (ASME). ASME is renowned for setting industry standards for a wide range of mechanical engineering practices, covering areas such as design, manufacturing, and operational safety. It provides guidelines and codes that help engineers ensure safety and quality in mechanical systems and components.

ASME is instrumental in promoting the application of engineering principles and practices through its standards, which are widely adopted across industries. This includes the development of norms related to pressure vessels, piping systems, and energy systems, which are critical for ensuring operational safety and performance in mechanical engineering applications.

In contrast, while ASTM focuses on developing standards for materials, products, systems, and services, and the NFPA concentrates on fire protection standards, and AIHA addresses industrial hygiene and occupational health, ASME specifically targets the needs of mechanical engineering.
