1、Designation:D146/D146M04(Reapproved 2020)Standard Test Methods forSampling and Testing Bitumen-Saturated Felts and WovenFabrics for Roofing and Waterproofing1This standard is issued under the fixed designation D146/D146M;the number immediately following the designation indicates the yearof original
2、adoption or,in the case of revision,the year of last revision.A number in parentheses indicates the year of last reapproval.A superscript epsilon()indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the U.S.Department of Defense.
3、1.Scope1.1 These test methods cover the sampling and examinationof felts or woven fabrics,saturated or impregnated but notcoated with asphaltic or coal-tar materials,for use in water-proofing or for the construction of built-up roof coverings.1.2 The values stated in either SI units or inch-pound un
4、itsare to be regarded separately as standard.The values stated ineach system may not be exact equivalents;therefore,eachsystem shall be used independently of the other.Combiningvalues from the two systems may result in nonconformancewith the standard.1.3 This standard does not purport to address all
