ASTM

ASTM International, originally the American Society for Testing and Materials, is a globally active organization that develops and publishes voluntary consensus technical standards for a wide range of materials, products, systems, and services. Standards cover metals, construction, petroleum, consumer products, environment, energy, and more. While based in the United States, its membership and standards are used worldwide.

Founded in 1898, ASTM adopted the acronym as its official name in 2001 to reflect an international scope. The organization is headquartered in West Conshohocken, Pennsylvania.

Standards are developed by committees comprising volunteers from industry, academia, government, and other stakeholders. The process uses a formal balloting and public review to achieve consensus before publication. ASTM classifies standards as test methods, specifications, guides, and terminology, and they are updated periodically to reflect advances in science and technology.

ASTM publishes its standards in the Annual Book of ASTM Standards and through digital platforms. Standards are voluntary but are widely referenced in procurement, product development, and government regulations, where incorporation by reference makes them legally enforceable in some contexts.

Governing structures include a Board of Directors, a Council, and numerous technical committees. Members include individuals, corporations, and government agencies contributing expertise and voting rights. The organization maintains a formal process to ensure openness and consensus.

ASTM standards play a central role in quality control, safety testing, and interoperability across industries such as construction, manufacturing, energy, and environmental management.
