标准范围

ISO 1833-17:2006规定了一种使用硫酸测定去除非纤维材料后，由氯乙烯均聚物（氯化与否后）和棉、粘胶、铜、莫代尔、醋酸盐、三醋酸盐、聚酰胺、聚酯、某些丙烯酸和某些变性丙烯酸纤维组成的氯纤维二元混合物制成的纺织品中氯纤维百分比的方法。[相关的改性丙烯酸树脂是指当浸入浓硫酸（密度为1.84 g/ml）中时产生清澈溶液的树脂。]可以使用该方法，尤其是代替ISO 1833中描述的方法-12和ISO 1833-13，在所有情况下，初步试验表明氯纤维在二甲基甲酰胺或二硫化碳和丙酮的共沸混合物中均不完全溶解。

ISO 1833-17:2006 specifies a method, using sulfuric acid, to determine the percentage of chlorofibres, after removal of non-fibrous material, in textiles made of binary mixtures of chlorofibres based on homopolymers of vinyl chloride (after-chlorinated or not) and cotton, viscose, cupro, modal, acetate, triacetate, polyamide, polyester, certain acrylic and certain modacrylic fibres. [The modacrylics concerned are those which give a limpid solution when immersed in concentrated sulfuric acid (density 1,84 g/ml).]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.
