标准编号：ISO 17710:2002

中文名称：塑料-聚亚氨脂产品使用的多元醇-不饱和状态微量滴定法测定

英文名称：Plastics — Polyols for use in the production of polyurethane — Determination of degree of unsaturation by microtitration

标准范围

本国际标准规定了一种微量滴定法，用于测量聚氨酯生产中使用的聚醚多元醇的不饱和度。它基于醋酸汞与多元醇中双键的反应。它不适用于不饱和度与羰基、羧基或腈基共轭的化合物。被测产品必须基本干燥，不含无机盐，尤其是卤化物。

This International Standard specifies a microtitration method to measure the degree of unsaturation in polyether polyols used in the production of polyurethanes. It is based on the reaction of mercuric acetate with double bonds in the polyol. It does not apply to compounds in which the unsaturation is conjugated with carbonyl, carboxyl or nitrile groups. The product being measured must be essentially dry and free of inorganic salts, especially halides.
