ASTM Committee D22 on Air Quality was formed in 1951. D22 meets twice a year, in April and October, with approximately 100 members attending over three days of technical meetings. The Committee, with a membership of over 400, currently has jurisdiction of over 145 standards, published in the Annual Book of ASTM Standards; Volume 11.07. D22 has 7 technical subcommittees that maintain jurisdiction over these standards. Information on this subcommittee structure and D22's portfolio of approved standards and Work Items under development are available from the List of Subcommittees, Standards and Work Items below. These standards have, and continue to play, a preeminent role in all aspects relating to the methodology for sampling and analysis of source emissions, ambient, workplace and indoor atmospheres, and meteorological conditions.
