Customer Acceptance Standard No. Date: Supersedes: Page: FIBERGLASS CONTINUOUS FILAMENT YARN FOR THE ELECTRICAL INDUSTRY DESCRIPTION Fiberglass yarn is a natural, lustrous, white, continuous filament yarn, which is twisted on various supply packages. The yarns are smooth, non-cellular and generally cylindrical in form. The yarns are made of glass of high stability and durability and are with the exception of sizing ingredients, inorganic, incombustible and will neither expand nor contract with moisture changes. The glass composition meets the certification for “E” glass as defined by ASTM’s D 578-00 Standards Specification for Glass Fiber Strands. The individual glass fibers do not tend to absorb moisture and are extremely flexible. The sizing may be burned off the yarn under certain conditions. Weathering tests have indicated comparatively unlimited stability under repeated cycles of heat, cold, sunlight, dampness and drying. USE These yarns are used for further fabrication, plying, winding, braiding, heat cleaning, heat treating, coating and impregnating of sleeving and tubings and banding tapes. OR For braiding and serving on wire and cable and magnet wire and other miscellaneous electrical applications. This specification is subject to change without notice.
