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. Greige glass fiber tapes and webbings are produced in two types: type A - medium texture, and type B - open texture. The fabric count, yarn number, filament diameter, strand construction, twist direction, twist level, weave type, length per unit mass, thickness, breaking force, width, length, ignition loss, and visual appearance shall be tested to meet the requirements prescribed.
This abstract is a brief summary of the referenced standard. It is informational only and not an official part of the standard; the full text of the standard itself must be referred to for its use and application. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date.
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 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.
1.4 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.
