标准摘要
[中文适用范围]： 本文件规定了一种使用甲酸测定由聚酰胺与棉、粘胶纤维、铜氨纤维、莫代尔纤维、莱赛尔纤维、聚酯、聚丙烯的混合物制成的纺织品中去除非纤维物质后聚酰胺纤维的质量百分比的方法、氯纤维、丙烯酸纤维、玻璃纤维、弹性多酯、弹性烯烃和三聚氰胺，或 — 羊毛（如果羊毛含量小于或等于 25%），或动物毛纤维。 当羊毛含量超过25%时，本文件不适用； ISO 1833-4 适用。 [外文原描述]： ISO 1833-7:2017 specifies a method, using formic acid, to determine the mass percentage of polyamide fibre, after removal of non-fibrous matter, in textiles made of mixtures of - polyamide with - cotton, viscose, cupro, modal, lyocell, polyester, polypropylene, chlorofibre, acrylic, glass fibre, elastomultiester, elastolefin and melamine, or - wool (if the wool content is less than or equal to 25 %), or animal hair fibres. ISO 1833-7:2017 does not apply when the wool content exceeds 25 %; ISO 1833-4 applies.
