D579-97 Standard Specification for Greige Woven Glass Fabrics

Developed by Subcommittee: D13.18; Adoptions: DOD Adopted; Building Codes; Book of Standards Volume: 07.01

1. Scope

1.1 This specification primarily covers greige fabrics woven from "E" electrical glass fiber yarns. This specification can also be applied to fabrics made of other glass fiber types as agreed upon between the purchaser and the seller.

1.2 This specification specifies the terminology, definitions, general requirements and physical requirements for greige glass fiber fabrics. 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 inch-pound units and in SI units. "Inch-pound units" is the technically correct name for the customary units used in the United States. "SI" units is the technically correct name for the system of metric units known as the International System of Units. The values stated in either acceptable metric units or other units shall be regarded separately as standard. The values expressed in each system may not be exact equivalents; therefore, each system must be used independently of each other, without combining values in any way.

1.4 This standard does not purport to address all of the safety problems 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.

Note 1-This specification is one of a series to provide a substitute for the following Military Specifications: MIL-Y-1140H MIL-C-9084C Additional ASTM specifications in this series are currently being drafted and will appear in the Annual Book of ASTM Standards , as available. These are to include finished glass fabrics, glass tapes, glass sleevings, glass yarns, glass cords, glass sewing thread, and finished laminates made from finished glass fabrics.

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.
