On October 19, 1918 the American Engineering Standards Committee (AESC) was formed by the American Institute of Electrical Engineers (now IEEE), the American Society of Mechanical Engineers (ASME), American Society of Civil Engineers (ASCE), the American Institute of Mining and Metallurgical Engineers (AIMME) and the American Society for Testing Materials (ASTM). Its purpose was to establish a national body to coordinate standards development and to serve as a clearinghouse for the work of standards developing agencies. The U.S. Departments of War, Navy and Commerce were invited to join this organization. AESC became the American National Standards Institute (ANSI) in 1969.
