2、 of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This qualitative test method determines the capability ofasphalt-based roofing or waterproof
3、ing material to seal arounda fastener that penetrates the material and prevent transmissionof liquid water through the material at the penetration underdefined conditions.1.2 This test method is provided for adoption by ASTM orother consensus-based roofing and waterproofing productspecifications as
4、a standardized means to evaluate capability toseal around a fastener. Performance of this test method aftersubjecting the product to conditioning intended to simulateenvironmental stresses and strains is not prohibited.1.3 The text of this test method references notes andfootnotes which provide expl

Summary of Test Method4.1 The capability of asphalt-based roofing or waterproofingmaterials to seal around a
9、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 theassembly for water passage for a period of time.4.2 The test method includes protoc
10、ols 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 In some situations, penetration through asphalt-basedroofing or waterproofing mater
11、ials 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 theconstruction process, it is reasonable to expect that materialsdesigned to limit migration o
12、f liquid 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.

44、adapplicability for evaluating roofing and waterproofing productsemployed in a variety of end uses. Therefore, it does notcontain a single set of test parameters that apply to all producttypes. Instead, the method is designed to be referenced byproduct specifications, and allows the user or a refere
45、ncingproduct specification to select a Protocol appropriate for use inevaluating the material of interest.X1.2 This test method is structured to accommodateaddition of new protocols as needed to address new products ordifferent end uses. A protocol establishes test parameter levelsappropriate for th

Establishment of appropriate “simu-lations” is left to the discretion of product specification taskgroups that choose to reference this test method for fastenerseal capabi
47、lity evaluation. Those task groups contain thenecessary product and application expertise to develop mean-ingful “simulation” methodology, and can choose to requirefastener seal capability testing before or after any relevant“simulation.”D 7349 08a4X2.
