ASTM WK26115

    New Test Method for Water Absorption by Immersion of Thermal Insulation Materials

    (What is a Work Item?)

    Developed by Subcommittee: C16.33 | Committee C16 | Contact Staff Manager



    WK26115

    1. Scope

    1.1 This test method determines the amount of water retained (excluding surface water) by flat thermal insulations after these materials have been fully immersed in liquid water for a prescribed time interval under isothermal conditions. This test method is intended to be used for the characterization of materials in the laboratory. It is not intended to simulate any particular environmental condition that may be encountered in building construction applications. 1.2 This test method does not address all the possible mechanisms of water intake and retention and related phenomena for flat thermal insulations. It relates only to those conditions outlined in 1.1. Determination of moisture accumulation in thermal insulations as a result of partial immersion, water vapor transmission, internal condensation, freeze-thaw cycling, or a combination of these effects requires different test procedures. 1.3 This test method does not address or attempt to quantify the drainage characteristics of materials. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not necessarily equivalent. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

    Test methods are being removed from C209.
