ISO 12775:1997

Overview - ISO 12775:1997 (glass types and test methods)

ISO 12775:1997 provides a consolidated set of guidelines that surveys the main types of glass of normal bulk‑production composition and the established test methods for their chemical and physical properties. The standard helps manufacturers, users and laboratories compare glass types (e.g., soda‑lime, borosilicate 3.3, alkaline‑earth silicates, lead silicates) and choose appropriate test procedures and classifications for hydrolytic resistance, , and thermal/physical behaviour.
