1、Designation: D 7349 08Standard Test Method forDetermining the Capability of Roofing and WaterproofingMaterials to Seal around Fasteners1This standard is issued under the fixed designation D 7349; the number immediately following the designation indicates the year oforiginal adoption or, in the case
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 waterproofi
3、ng 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 a
4、 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 expla
5、natory material. These notes andfootnotes (excluding those in tables and figures) shall not beconsidered as requirements of the standard.1.4 The values stated in SI units are to be regarded asstandard. The values in parentheses are mathematical conver-sions to inch-pound units that are provided for
6、informationonly and are not considered standard.1.5 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of reg

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.
