ISO 8516:2011为适用于由纺织玻璃纤维单纱或折叠纱制成的变形纱的规范提供了依据。 变形玻璃纱可以通过几种工艺生产。它们可以从单股或两股或更多股开始制造，其中一股或多股已经“打开”，以提供变形纱的“体积”方面。 变形玻璃丝用于各种应用，例如绝缘、过滤、装饰纺织品的制造、塑料加固和包装材料的制造。

ISO 8516:2011 provides a basis for a specification applicable to textured yarns made from single or folded yarns of textile glass. Textured glass yarns can be produced by several types of process. They can be made starting either from a single strand or from two or more strands in which one or more have been "opened" to give the "bulky" aspect of textured yarn. Textured glass yarn is used in various applications, for example insulation, filtration, the manufacture of decorative textiles, the reinforcement of plastics and the manufacture of packing materials.
