标准范围

ISO 4802?2:2010规定了玻璃容器内表面在(121±1)°C温度下被水侵蚀(60±1)min时的耐水解性测定方法。通过使用火焰原子发射光谱法或吸收光谱法测定萃取溶液中钠和其他碱金属或碱土金属氧化物的含量来测量耐水解性(火焰光谱法)。ISO 4802?2:2010还根据ISO 4802本部分规定的方法确定的内表面耐水解性规定了玻璃容器的分类。ISO 4802?2:2010中规定的试验方法可能不适用于表面经过硅处理的容器(例如准备直接填充的容器)。

ISO 4802?2:2010 specifies methods 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).ISO 4802?2:2010 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.The test method specified in ISO 4802?2:2010 might not be applicable to containers whose surfaces have been treated with silicon (e.g. containers that are ready for direct filling).
