标准摘要
[中文适用范围]： 本文件规定了：a) 玻璃容器内表面在 (121±1)°C 温度下经 (60±1) 分钟的水侵蚀时，内表面耐水解性的测定方法。抗水解性的测定是通过滴定用盐酸溶液产生的已知等分萃取溶液来测量的，在这种情况下，抗水解性与所需的酸量成反比；b) 根据本文件规定的方法确定的内表面耐水解性对玻璃容器进行分类。 [外文原描述]： This document specifies: a) a method for determining the hydrolytic resistance of the interior surfaces of glass containers when subjected to attack by water at (121 ± 1) °C for (60 ± 1) min. The resistance is measured by titration of a known aliquot portion of the extraction solution produced with hydrochloric acid solution, in which case the resistance is inversely proportional to the volume of acid required; b) a classification of glass containers according to the hydrolytic resistance of the interior surfaces determined by the methods specified in this document.
