ASTM E1996 Impact Window Testing Explained for Homeowners

What ASTM E1996 Actually Tests

In Redington Beach FL, a lot of window advice gets reduced to "get impact glass," but ASTM E1996 is the testing standard that explains what that really means.

What Happens During Impact Window Testing

The two common test types are large missile impact and small missile impact. The first is the better-known test for hurricane exterior openings, while the second is used in other assemblies and lower-risk applications.

The impact is only part of the story. After the strike, the specimen is then subjected to cyclic pressure changes that simulate gusting winds pushing and pulling on the opening.

The real value is in keeping the opening functional. Even if the glass is damaged, the system should keep the structure from taking a direct hit from wind and water.
