ISO 4802？1:2010规定了一种测定玻璃容器内表面在121°C±1°C温度下被水侵蚀60分钟±1分钟时的耐水解性的方法。该耐水解性通过滴定用盐酸溶液产生的萃取溶液的已知等分部分来测量，在这种情况下，电阻与所需酸的体积成反比。ISO 4802-1:2010还规定了根据ISO 4802本部分规定方法确定的内表面耐水解性对玻璃容器进行分类。

ISO 4802？1:2010 specifies a method for determining the hydrolytic resistance of the interior surfaces of glass containers when subjected to attack by water at 121 °C ± 1 °C for 60 min ± 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.ISO 4802？1:2010 also specifies a classification of glass containers according to the hydrolytic resistance of the interior surfaces determined by the methods specified in this part of ISO 4802.
