ASTM Committee D05 on Coal and Coke was formed in 1904. D05 meets twice a year, usually in May and October, with about 50 members attending over four days of technical meetings capped by a presentation on relevant topics in the Coal and Coke industry. The Committee, with a membership of approximately 275, currently has jurisdiction over 79 standards, published in the Annual Book of ASTM Standards, Volume 05.06. D05 has 10 technical subcommittees that maintain jurisdiction over these standards.
