[中文适用范围]： 本文件规定了一种测定纤维增强产品中纤维长度的方法。该方法适用于模塑材料和模塑部件。规定的测试条件将此方法的应用限制为用短玻璃纤维（长度小于 1 毫米）增强的热塑性塑料，即在加入模塑材料和模塑之前长度小于或等于 7.5 毫米的纤维。 [外文原描述]： This document specifies a method of determining the length of the fibres present in a fibre-reinforced product. The method is applicable to moulding materials and to moulded parts. The test conditions specified limit the application of this method to thermoplastics reinforced with short glass fibres (less than 1 mm long), i.e. fibres whose length is less than or equal to 7,5 mm prior to incorporation in the moulding material and moulding.
