What is the classification of tempered glass based on impact tests?

Tempered glass is classified as both Category I and Category II based on impact tests. This classification stems from the rigorous testing standards that tempered glass must meet, which evaluates its ability to withstand impact and breakage.

Category I generally indicates that the glass can resist higher levels of impact, while Category II reflects a slightly lower performance but still meets the minimum safety standards set forth for certain applications. The dual classification highlights the versatility of tempered glass—it is engineered to meet diverse structural and safety requirements.

Understanding this classification is essential for glazing contractors, as it informs them about the glass's application possibilities and compliance with building codes and safety regulations. By being categorized in both segments, tempered glass provides assurance in various scenarios, making it a preferred choice in construction and architectural designs where safety and durability are paramount.
