ASTM E1996 Impact Window Testing Explained for Homeowners

What ASTM E1996 Actually Tests

The testing process is designed to mimic hurricane debris, not everyday wear. The objective is not to make glass invincible, but to see if the assembly can still protect the opening after being hit.

Depending on the application, the product is tested with either large missile impact or small missile impact. Homeowners usually hear more about large missile testing because it applies to many exterior openings in hurricane-prone zones.
