标准摘要
[中文适用范围]： 本国际标准规定了两种测定浸渍粗纱断裂拉伸应力的方法： ——使用模压环氧拉片制作的测试样品的参考方法； ——使用没有标签或简单纸板或复合标签的测试样本的简短方法。 这些方法适用于组装（多股）和直接（复丝）粗纱；然而，参考方法可用于各种线密度，但短方法仅针对 1 200 tex 粗纱进行描述，这是使粗纱中的纤维在浸渍过程中最容易展开的线密度。 [外文原描述]： ISO 9163:2005 specifies two methods for the determination of the tensile stress at break of an impregnated roving: a reference method using test specimens produced with moulded epoxy tabs; a short method using test specimens with no tabs or simple cardboard or composite tabs. The methods are applicable to both assembled (multistrand) and direct (multifilament) rovings; nevertheless the reference method may be used for various linear densities, but the short method is described for 1200 tex rovings only, which is the linear density that allows the roving to spread out most easily to give a flat tape.
