Standard Specification for Greige Woven Glass Fabrics

ABSTRACT
This specification covers the general and physical requirements for greige fabrics woven from “E” electrical glass fiber yarns. The yarn shall be a continuous filament, free of any free alkali metal salts, such as soda or potash, and foreign particles, dirt, and other impurities. The fabric shall be furnished in rolls and shall be wound in spiral tubes. The materials shall be tested and shall conform to the following requirements: fabric count; yarn numbers for both the warp and filling yarns; filament diameter; strand construction; twist direction wherein the primary twist in the singles strands shall be “Z” twist and the final twist in the plied yarns shall be “S” twist; twist level; fabric weave type which shall include crowfoot, leno, mock leno, plain, eight-harness satin, and twelve-harness satin; mass per unit area; thickness; breaking strength; width including both selvages but excluding any feathered edges; fabric roll length, length between splices, and number of splices per roll; and ignition loss. The fabrics shall also be examined for defects such as bias or bowed filling; baggy, ridged, or wavy cloth; cut or tear; hole; spots, streaks, or stains; foreign inclusions; tender or weak spot; smash; broken, missing ends or picks; floats and skips; light and heavy marks; crease; waste; weave separation; brittle or fused area; selvage defects; selvage leno ends out; and feather edges.
SCOPE
1.1 This specification 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 supplier.
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.
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 non-conformance with the standard.
1.4 This specification is one of a series to provide a substitute for Military Specifications: MIL-Y-1140 Yarn, Cord, Sleeving, Cloth, and Tape-Glass; and MIL-C-9084 Cloth, Glass Finished for Resin Laminates.
1.5 Additional ASTM specifications in this series have been drafted and appear in current editions of the Annual Book of ASTM Standards. These include finished glass fabrics, unfinished glass fabrics, glass tapes, glass sleevings, glass cords, glass sewing threads, and finished laminates made from finished glass fabrics.
1.6 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.
