3、its information was editorially corrected in June 2012.1. Scope1.1 This specification covers asphalt impregnated and coated glass fiber base sheet, with or without perforations, for use as thefirst ply of the built-up roofing. When not perforated, this sheet is suitable for use as a vapor retarder,
4、with a solid mopping ofasphaltic material, under roof insulation or between multiple layers of roof insulation.1.2The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only.1.2 The values stated in either SI units or inch-pound units are to b
5、e regarded separately as standard. The values stated in eachsystem may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from thetwo systems may result in non-conformance with the standard.2. Referenced Documents2.1 ASTM Standards:2D146 Test
