Significance and Use5.1 In some situations, penetration through asphalt-basedroofing or waterproofing materials by

11、 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 theconstruction process, it is reasonable to expect that materialsdesigned to limit migration of liqui

12、d water at the interfacebetween the penetrating fastener and the material will do so.This qualitative test method provides a means to evaluate theability of a material to limit water migration at fastenerpenetrations when tested under defined conditions.6.
