Committee D28 on Activated Carbon

Staff Manager: Kelly Paul

ASTM Committee D28 on Activated Carbon was formed in 1962. D28 meets twice a year, usually in April and October, with about 15 members attending two days of technical meetings. The Committee, with a current membership of 41, has jurisdiction of 29 standards, published in the Annual Book of ASTM Standards, Volume 15.01. D28 has 3 technical subcommittees that maintain jurisdiction over these standards. These standards have and continue to play a preeminent role in determining acid extractable content in activated carbon by ashing, moisture in activated carbon, carbon tetrachloride activity, total ash content, ball-pan hardness, iodine number and pH of activated carbon.
