Scope

This document specifies a method for testing the resistance of raw optical glasses to attack by aqueous alkaline phosphate-containing detergent solutions (phosphate solutions) at 50 °C and a classification of optical glasses according to the aqueous alkaline phosphate-containing detergent resistance (phosphate resistance) determined by this method.

This document is applicable to samples of raw optical glasses.
