ASTM WK45922

    Withdrawal of F1471 - 09 Standard Test Method for Air Cleaning Performance of a High-Efficiency Particulate Air- Filter System

    (What is a Work Item?)

    Active Standard: F1471 - 09

    Developed by Subcommittee: D22.05 | Committee D22 | Contact Staff Manager


    This standard is being balloted for withdrawal with no replacement due to a low level of interest and because the testing of the performance of HEPA systems is done with a suite of IEST (Institute of Environmental Science and Technology) standards and not with F1471. This determination is based on discussions with several individuals from the filtration industry.
