ASTM Standards

Definition

ASTM standards are guidelines and specifications developed by ASTM International, an organization that sets consensus standards for materials, products, systems, and services. These standards are vital in ensuring quality and safety across various industries, including construction, manufacturing, and materials science. They provide a basis for evaluating the performance and reliability of materials and components, which is essential for understanding yield criteria and failure theories.
