9、d4.1 The capability of asphalt-based roofing or waterproofingmaterials to seal around a penetrating fastener and prevent thepassage of liquid water at the fastener/material interface isdetermined by penetrating the material with a fastener,erectinga water column over that penetration,and monitoring
10、theassembly for water passage for a period of time.4.2 The test method includes protocols that establish levelsfor the test method parameters.The protocol used to evaluatea material is designated in a standard specification for thematerial or by the user of this test method.5.Significance and Use5.1
11、 In some situations,penetration through asphalt-basedroofing or waterproofing materials by fasteners is a requiredpart of the material installation process or occurs duringinstallation of other system components.When fasteners pen-etrate the material as a purposeful and planned part of theconstructi
