Rating for American Security Wall Safes
Fire
Endurance Test
After heat sensors and paper are
placed inside the safe, the unit is locked and exposed to a uniformly
distributed fire. The furnace is regulated to reach a maximum temperature of
1700°F for a period of one hour then allowed to cool without opening the
furnace. The interior temperature is recorded throughout the test and during the
cooling period until a definite drop is shown and must never exceed 350°F.
Once cooled, the unit is opened
and examined for usability. The units locking mechanisms and parts fastenings
are examined for security and the interior examined for visible evidence of
undue heat transmission
