ASTM Committee C24 on Building Seals and Sealants was formed in 1959. C24 meets twice a year, usually in January and June, with about 50 members attending three days of technical meetings. Semi-annually, the Committee sponsors the Charles J. Parise Symposium on the Science and Technology of Building Seals, Glazing and Waterproofing, which consists of presentations on relevant topics in the sealant industry. The Committee, with a membership of 186, currently has jurisdiction over 99 standards, published in the Annual Book of ASTM Standards, Volume 04.07. C24 has 10 technical subcommittees that maintain jurisdiction over these standards. Information on this subcommittee structure and C24's portfolio of approved standards and Work Items under construction are available from the List of Subcommittees, Standards and Work Items below. These standards play a preeminent role in all aspects important to the building industry with a concentration in aerosol foam sealants, caulking compounds, elastomeric sealants, glazing compounds, preformed sealing tapes, and preformed gaskets. The Committee also plays a preeminent role in the ISO process by housing the US TAG to ISO/TC 59 Building Construction /SC8 on Jointing Products. More
