    Abstract

    This specification covers the requirements for continuous glass filament greige braided tubular sleeving and is suitable for use as electrical insulation and for structural and mechanical applications. Ultimate users will be assisted by designating the types of these products that are typical in the industry. Glass fiber greige braided tubular sleeving is produced in one type and two styles within that type and uses yarns designated namely Type G, Style A, and Style B. All yarns for braided tubular sleeving shall be electrical classification, (E glass), continuous filament glass yarns, and shall fall within the chemical composition that is utilized for general applications as described. The fiber shall be free of any free alkali metal oxides, such as soda or potash, and foreign particles, dirt, and other impurities. The primary twist in the singles strands shall be Z twist and the final twist in the plied yarns shall be S twist. Other properties such as yarn number, strand construction, twist level, ends per carrier, carrier number, picks per unit length, inside diameter, wall thickness, length per unit mass, length per package, and ignition loss shall conform to the requirements specified. The braided tubular sleeving shall be generally uniform in quality and condition, clean, smooth, and free of foreign particles and defects detrimental to fabrication, appearance, or performance.

    This abstract is a brief summary of the referenced standard.

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. Scope

    1.1 This specification covers the requirements for continuous glass filament greige braided tubular sleeving and is suitable for use as electrical insulation and for structural and mechanical applications.

    1.2 This specification is intended to assist ultimate users by designating the types of these products that are typical in the industry.

    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 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.
