ASTM Standards

Definition

ASTM standards are established guidelines and criteria developed by ASTM International, which is an organization that creates and publishes voluntary consensus technical standards for materials, products, systems, and services across various industries. These standards are critical in ensuring quality, safety, and efficiency in engineering practices, particularly in the evaluation and testing of tribological systems and their components, the importance of tribology in engineering, the measurement of friction forces, aerospace applications, and abrasive wear mechanisms.
