Large/Small Impact Tests

Large missile impact tests simulating large wind-borne debris, such as tree limbs, sign  posts and other large objects, are required for products such as entrances and storefronts installed up to 30 feet above grade.



Small missile impact tests simulating smaller wind-borne debris, such as roof gravel, are required for products installed more than 30 feet above grade, such as curtain wall, sliding doors and windows. Test requirements call for entire systems – glass, frames, sealants, locks and fasteners to resist wind-borne debris followed by severe pressure cycling.
