    WK42373

    1. Scope

    1.1 This test method establishes a method to determine the measured effect semi-air permeable fibrous thermal insulation material has on the rate of air volume transfer in retrofit residential side walls. 1.2 This test method describes an apparatus that is used to determine the rate of air volume transfer through a standardized residential sidewall. The precision and bias of the apparatus and this test method can be determined by repeated, controlled testing. 1.3 This test method established comparative values for the rate of air volume transfer of different semi-air permeable fibrous materials installed using a dense pack method at varying densities. 1.4 This test method is applicable to measuring the rate of air volume transfer through a wide range of ambient conditions. 1.5 This test method does not account for all details of various types of construction. 1.6 Units--The values stated in SI units are to be regarded as the standard. The values given in parentheses are mathematical conversions to inch-pound units that are provided for information only and are not considered standard. 1.7 The definition for terms used in this test method are found in Terminology C168 or within this test method. 1.8 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.
