Annex A (informative) Bibliography

Defines a survey of glass types and of test procedures for chemical and physical properties to provide consumers and glass producers of normal bulk-production composition with the opportunity for comparison of different types of glass and test methods, and to decide which are of interest for a special demand or use. Classifies the different glass types of normal bulk-production composition in accordance with chemical composition and indicates the different test methods, together with classifications in accordance to chemical resistance.

This International Standard establishes a survey of glass types and of methods for testing their chemical and physical properties to give, for example, consumers and producers of glass of normal bulk-production composition the possibility to compare the different types of glass and test methods and to decide which are of interest for a special demand or use. For this purpose, these comprehensive guidelines give a classification of the different glass types of normal bulk-production composition according to the chemical composition and indicate the different test methods and, where they exist, the classifications according to chemical resistance.
