标准范围

本文件规定:A）？一种测定玻璃容器内表面在（121？±？1）？°C（60？±？1）？分钟。通过滴定用盐酸溶液产生的提取溶液的已知等分部分来测量电阻，在这种情况下，电阻与所需酸的体积成反比；b）？根据本文件规定的方法测定的内表面耐水解性对玻璃容器进行分类。

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.
