This International Standard specifies a method for testing the resistance of raw optical glasses to attack by aqueous acidic solutions at 25 ℃ and a classifi-cation of optical glasses according to the acid resis-tance determined by this method.
This International Standard contains basic information about the chemical durability of the glass tested.
It is applicable to samples of raw optical glasses.
NOTE 1 The test method may also be used for other types of glasses.
