ASTM Committee F11 on Vacuum Cleaners was formed in 1972. F11 meets twice a year, at the May and November Committee Weeks, with about 35 members attending over 3 days of technical meetings. The Committee, with a current membership of approximately 84 members, has jurisdiction over 41 standards published in the Annual Book of ASTM Standards, Volume 15.11. F11 has 8 technical subcommittees that maintain jurisdiction over these standards. Information on this subcommittee structure and F11's portfolio of approved standards and Work Items under development are available from the List of Subcommittees and Standards. These standards have and continue to play a preeminent role in all aspects important to the effective standardization of vacuum cleaners, including filtration efficiency, air performance characteristics, cleanability, durability and reliability.
