ASTM E2025-99(2006)

This test method is intended for determining the ability of a fenestration component, fenestration assembly, or impact protection system to resist specified impact energies.

The test apparatus, referenced herein, is capable of applying a variety of impacts to a specimen as the impactor head may be fabricated into a variety of shapes and from materials having different degrees of hardness. The user is able to simulate a specific type of impact and the impact energy with this apparatus.

There is a need to correlate the damage to fenestration assemblies from the impacts in question with the impacts delivered by the test apparatus in order for the test results to be properly interpreted. Due to the nature of the test apparatus, care must be taken when interpreting the results of a specific test to actual performance in the field. The impact energies involved in a pendulum impact cannot be directly transferred to impact energies applied by other devices, for example, projectiles; therefore, the performance of a specimen to the impacts applied by this test method are not directly transferable to performance in actual use. The application of impact energies to a specimen, as applied in this test method, however, does provide valuable information regarding the ability of the specimen to resist damage when impacted.

Note 1—Use Test Method E 1886 for determining the performance of fenestration components subjected to impacts from windborne debris in a windstorm environment.

When using this test method to compare the performance of products the same impact nose, impact device mass and impact speed must be applied to each product tested.

1.1 This test method covers the evaluation of the resistance of fenestration components, fenestration assemblies, and impact protection systems to specified impact energies.

1.2 Window, glazed door, and skylight assemblies covered by this test method also include individual components, such as the glazing in-fill.

This standard does no purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
