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.
