No. Date: Supersedes: Page: CUSTOMER ACCEPTANCE STANDARD FIBERGLASS CONTINUOUS FILAMENT YARN FOR THE WEAVING INDUSTRY DESCRIPTION Fiberglass yarn is a natural, lustrous, white, continuous filament yarn which is evenly twisted on 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. I. USE These yarns are used for further fabrication typically: warping, weaving for glass fabrics and tapes. III.

Therefore, the yarn name is only used as a descriptor. The table in section V. must be utilized to obtain the actual bare glass yield of a yarn product.
