The number of impacts a glazing assembly can withstand before penetration depends on the specific ASTM F3561 forced entry level being tested. The standard utilizes a structured sequence of initial impacts from a calibrated pendulum device to weaken the glass before tool-based penetration attempts begin.
According to the ASTM F3561 testing protocol, the required impacts for each level are as follows:
- Level 1: Requires 5 initial impacts and must provide 60 seconds of resistance.
- Level 2: Requires 7 initial impacts and must provide 120 seconds of resistance.
- Level 3: Requires 10 initial impacts and must provide 180 seconds of resistance.
- Level 4: Requires 15 initial impacts and must provide 300 seconds of resistance.
An assembly passes the test if it denies full penetration by the designated tools (such as screwdrivers, pry bars, or sledgehammers) for the entire duration of the level-specific resistance window after these impacts have been delivered.
