ASTM WK23911

    New Practice for Assessing the Airtightness of Joints Between Air-tight Assemblies

    (What is a Work Item?)

    WK23911

    1. Scope

    1.1 This practice is to determine the air permeance rating of joints between air tight assemblies, which are used as part of a total air barrier system in a building. 1.2 This practice is intended to determine the air barrier property/air leakage rate of the joints, junctions, overlaps, or interfaces between similar or dissimilar assemblies. This method provides a procedure for preparing the test assembly and further describes the application of products prior to conducting ASTM E 283. 1.3 This practice allows testing laboratories to accurately quantify the air leakage rate of specific sealing, taping or filling products using ASTM E 283 and reporting the data in L/(sm2) according to ASTM E 29. 1.4 This practice is used in conjunction with ASTM E 283. Although ASTM E 283 is a laboratory test method used with fenestration products, individuals interested in performing field air leakage tests on installed units should reference ASTM E 783. 1.5 There are no other known practices or test methods specific for testing the air leakage rate of materials used as joints between air-tight assemblies.

    This is for manufacturers of materials, contractors, qualilty assurance professionals to enable the evaluation of the airtightness performance of construction joints and junctions within the air barrier system.
