《GB/T 7690.5-2001增强材料 纱线试验方法 第5部分:玻璃纤维纤维直径的测定》由TC245(全国玻璃纤维标准化技术委员会)归口,主管部门为中国建筑材料联合会。
本标准规定了玻璃纤维产品中纤维平均直径(即实际直径的平均值)的二种测定方法,即纵向法和横截面法。本标准适用于定长纤维纱线、连续纤维纱线,也适用于织物或毡中纤维直径的测定。
Scope
This standard specifies two methods for measuring the average fiber diameter (that is, the average value of the actual diameter) in glass fiber products, namely the longitudinal method and the cross-sectional method. This standard applies to cut-to-length fiber yarns and continuous fiber yarns, as well as to the determination of fiber diameters in fabrics or mats. Note 1: The average diameter should not be confused with the nominal diameter. The nominal diameter is used to name the yarn and the material made of these yarns. It is consistent with the rounded value of the average diameter.
