该欧洲标准规定了测定具有与伯和仲碳原子连接的羟基的脂族和环状羟基化合物的羟基值的方法。 本欧洲标准适用于聚缩醛，感温材料，高固体聚合物多元醇和刚性多元醇和酚类。 该欧洲标准不适用于测定与叔碳原子连接的羟基。 注意此方法目前推荐用于中性精制产品。然而，对于含有过量酸性物质的产品，应进行验证以显示酸性物质不干扰或已经消除了酸性物质的干扰

This European Standard specifies a method for the determination of hydroxyl value of aliphatic and cyclic hydroxyl compounds with hydroxyl groups attached to primary and secondary carbon atoms. This European Standard is applicable to polyacetals, temperature sensitive materials, high solids polymer polyols and rigid polyols and phenols. This European Standard is not suitable for determination of hydroxyl groups attached to tertiary carbon atoms. NOTE This method is currently recommended for neutral refined products. However for products that contain an excess of acidic species a validation should be carried out to show that the acidic species either does not interfere or that the acidic species interference has been obviated.
