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 178, currently has jurisdiction over 73 standards, published in the Annual Book of ASTM Standards, Volume 05.06.
