1、Designation: D 4601 04Standard Specification forAsphalt-Coated Glass Fiber Base Sheet Used in Roofing1This standard is issued under the fixed designation D 4601; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last revi

2、sion. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.This standard has been approved for use by agencies of the Department of Defense.1. Scope1.1 This specification covers asphalt impregnated

3、 andcoated glass fiber base sheet, with or without perforations, foruse as the first ply of the built-up roofing. When not perforated,this sheet is suitable for use as a vapor retarder, with a solidmopping of asphaltic material, under roof insulation or be-tween multiple layers of roof insulation.1.
