ASTM D580-99

Standard Specification for Greige Woven Glass Tapes and Webbings

SCOPE
1.1 This specification primarily covers greige tapes and webbings woven from "E" electrical classification glass fiber yarns. This specification can also be applied to tapes and webbings made of other glass fiber grades upon agreement between the purchaser and the supplier.  
1.2 This specification is intended to assist ultimate users by designating the types of these products that are typical in the industry. This specification permits the application of organic materials to the glass fiber yarn during manufacture that helps facilitate weaving. When used as permitted in this specification, such materials will not interfere with the intended end use requirements.  
1.3 This specification shows the values in both SI and inch-pound units. "SI" units is the technically correct name for the system of metric units known as the International System of Units. "Inch-pound" units is the technically correct name for the customary units used in the United States. The values stated in inch-pound units are to be regarded as the standard. The values in SI units are provided as information only.  Note 1-This specification is one of a series to provide a substitute for the following Military Specifications: MIL-Y-1140H Yarn, Cord, Sleeving, Cloth, and Tape-Glass MIL-C-9084C Cloth, Glass Finished for Resin Laminates
1.4 The following precautionary caveat pertain only to the test methods portions, Sections 26 through 41, of this specification. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
