本文件规定了一种使用浓硫酸测定氯纤维和某些其他纤维的质量百分比的方法，该方法在去除非纤维材料后，用于测定由以下混合物制成的纺织品中的氯纤维和某些其他纤维的质量百分比: -棉、粘胶、铜、莫代尔、lyocell、醋酸盐、三醋酸盐、聚酰胺、聚酯、弹性多酯、某些丙烯酸和某些变性丙烯酸纤维 具有 -氯纤维（基于氯乙烯均聚物）、聚丙烯、弹性烯烃、三聚氰胺和聚丙烯/聚酰胺双组分。 所涉及的改性丙烯酸树脂是指当浸入浓硫酸中时能提供清晰溶液的树脂。 在初步试验表明氯纤维在二甲基甲酰胺或二硫化碳与丙酮的共沸混合物中不完全溶解的所有情况下，可以使用该方法，尤其是代替ISO 1833-12和ISO 1833-13中所述的方法。交叉引用:ISO 1833-1ISO 1833-13ISO 1833- 12购买本文件时提供的所有当前修订版均包含在购买本文件中。

This document specifies a method, using concentrated sulfuric acid, to determine the mass percentage of chlorofibres and certain other fibres, after removal of non-fibrous material, in textiles made of mixtures of — cotton, viscose, cupro, modal, lyocell, acetate, triacetate, polyamide, polyester, elastomultiester, certain acrylic and certain modacrylic fibres with — chlorofibres (based on homopolymers of vinyl chloride), polypropylene, elastolefin, melamine and polypropylene/polyamide bicomponent. The modacrylics concerned are those which give a clear solution when immersed in concentrated sulfuric acid. This method can be used, particularly in place of the methods described in ISO 1833-12 and ISO 1833-13, in all cases where a preliminary test shows that the chlorofibres do not dissolve completely either in dimethylformamide or in the azeotropic mixture of carbon disulfide and acetone.Cross References:ISO 1833-1ISO 1833-13ISO 1833-12All current amendments available at time of purchase are included with the purchase of this document.
