ASTM International was organized in 1898, and is one of the largest voluntary standards development systems in the world. ASTM stands for American Society for Testing and Materials. ASTM International is a not-for-profit organization which provides a forum for producers, users, ultimate consumers, and those having a general interest (representatives of government and academia) to meet on common ground and write standards for materials, products, systems and services. ASTM has developed the standards for sound testing of floor systems.
