ASTM WK35913

    New Test Method for Whole Building Enclosure Air Tightness Compliance

    (What is a Work Item?)

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


    1. Scope

    1) This standard test method provides a quantitative field-test procedure and calculation method for assessing compliance of a building enclosure with an air tightness specification using fan- induced pressure differences. 2) Building setup conditions appropriate for testing the enclosures air tightness are defined in this standard. 3) Guidelines to identify the air barrier boundaries of the building enclosure to be tested are provided in this standard. 4) This test method applies to all building types and portions thereof. 5) This test method is applicable to typical indoor-outdoor temperature differentials and low to moderate wind pressure conditions.* 6) This standard defines two test procedures: multipoint regression and repeated single point pressure testing. 7) This standard allows for testing compliance with pressurization only, depressurization only or a combination.


    air leakage, air infiltration,


    Energy codes and specifications are increasingly requiring testing the air leakage of buildings. Although some standards exists none of them deal specifically with the test details required to determine code/specification compliance.

    The title and scope are in draft form and are under development within this ASTM Committee.
