本文件规定了测定涂料和清漆用树脂和粘合剂中羟基的滴定法。 这种方法主要适用于中性介质。酸性产品提供更高的价值；中性产品通过中和酸性氨基甲酸酯提供较低的值。对这些产品进行初步试验，以确保该方法的适用性。购买本文件时可获得的所有当前修订均包含在购买本文件中。

This document specifies a titrimetric method for determining the hydroxyl groups in resins and binders for paints and varnishes. This method is primarily suitable for neutral media. Acidic products provide higher values; neutral products provide, through neutralization of the acidic carbamates, lower values. For these products, preliminary tests are performed to ensure the applicability of the method.All current amendments available at time of purchase are included with the purchase of this document.
