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.
