标准范围

本文件规定了两种测试原始光学玻璃对酸性水溶液侵蚀的抵抗力的方法，并根据这些方法测定的耐酸性定义了光学玻璃的分类。表面法测试抛光板状光学玻璃在25？°C指定时间，并将通过该方法确定的等级表示为“SR-S”。粉末法测试粉碎的粒状光学玻璃在98？°C为1？h，并且表示通过该方法确定的类别为“SR-P”。

This document specifies two methods for testing the resistance of raw optical glasses to attack by aqueous acidic solutions and defines a classification of optical glasses according to the acid resistance determined by these methods.

The surface method tests the resistance of the polished plate-shaped optical glass to attack by aqueous acidic solutions at 25 °C for a specified time and indicates the class determined by this method as “SR-S”.

The powder method tests the resistance of crushed granular optical glass to attack by an acidic aqueous solution at above 98 °C for 1 h, and indicates the class determined by this method as “SR-P”.
