ASTM WK43749

    New Practice for Assessing the Airtightness of Penetrations through Air-tight Assemblies

    (What is a Work Item?)

    Developed by Subcommittee: E06.41 | Committee E06 | Contact Staff Manager


    1. Scope

    This practice is to determine the total air leakage rate attributable to penetrations through an air barrier which are part of an air barrier assembly, which then is used as part of a total air barrier system in a building.This practice is intended to determine the air leakage rate of the penetrations though an air barrier which are part of an air barrier assembly. This method provides a procedure for preparing the test assembly and further describes the application of products to the assembly prior to conducting ASTM E 2178. This practice allows testing laboratories to accurately quantify the air leakage rate of anchors, pipes, screws and other penetrations through the air barrier using ASTM E 283 and reporting the data in L/(sm2) according to ASTM E 29. For the purposes of this standard, the term penetrations refers to both the component penetrating the air barrier, and any sealant required for sealing the penetration to the air barrier as required by the manufacturer of the penetrating component. This practice is used in conjunction with ASTM E 2178.

    The purpose for drafting this standard was to establish a procedure to accurately quantify the air leakage rates of penetrations through air barrier materials. Currently, there are no other known practices or test methods specific for testing the air leakage rate of penetrations through airtight assemblies
