标准摘要
[中文适用范围]: 本文件规定了:a) 一种测定玻璃容器内表面在 (121±1)°C 温度下经 (60±1) 分钟的水侵蚀时耐水解性的方法。抗水解性的测定是通过使用火焰原子发射或吸收光谱法(火焰光谱法)测定萃取溶液中的钠和其他碱金属或碱土金属氧化物的量;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。本文件中规定的测试方法可能不适用于表面已进行功能改性处理的容器,例如硅胶(例如可直接灌装的容器)。 [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 determining the amount of sodium and other alkali metal or alkaline earth oxides in the extraction solution using flame atomic emission or absorption spectrometry (flame spectrometry); b) a classification of glass containers according to the hydrolytic resistance of the interior surfaces determined by the methods specified in this document. The test method specified in this document might not be applicable to containers whose surfaces have been treated for functional modifications, e.g. silicone (e.g. containers that are ready for direct filling).
