Established in 1970, E31 meets semi-annually as a committee in May and November. Members and visitors attend three days of meetings that include technical subcommittee sessions and a plenary meeting.
Some subcommittees occasionally meet on an accelerated basis.
The committee, with current membership of approximately 270 members, currently holds jurisdiction of over 30 approved standards and additional draft standards. Approved standards are published annually in June in the Annual Book of ASTM Standards, Volume 14.01.
