(2) Fire Endurance Tests
For this test, the container has items placed inside it. Interior items must be in contact with
the interior walls. The container is then closed, locked, and exposed to a uniformly
distributed fire. The fire temperature is regulated and increased
according to the Standard Time Temperature Curve. The
fire is continued for the period required for the classification desired
and allowed to cool without opening the furnace. The interior
temperature is recorded throughout the test and during the subsequent
cooling period until a definite drop is shown and must never exceed 150°F
or 350°F as the case may be. Once cooled, the unit is opened,
dismantled and its contents examined for usability. The units' locking
mechanism and part fastenings are examined for security and the interior
examined for any visible evidence of undue heat transmission. Regular
production units must again pass the Fire Endurance Test, 1 year after
the first test or 1 year after production of the tested unit began.

(3) Explosion Hazard
Test
The container to be tested is emptied, closed, locked and placed into a furnace preheated to
2000°F. This temperature is maintained for 30 minutes (20 minutes for
units rated1/2 hour) and if no explosion results, the unit is allowed to
cool without opening the furnace doors. Once cooled, the unit is opened,
dismantled and examinations made regarding the heat insulating
properties of the sample such as condition of interior finish, security
of interior equipment, lock part fastenings, and any signs of undue
transmission of heat or moisture.

(4) Fire & Impact Test
After the units' contents are placed inside and in contact with the
interior walls, the unit is closed, locked and exposed to the Standard
time as in the Fire Endurance Test for the period of time stated for
that classification. Within two minutes, the unit is removed from the
furnace and dropped 30' onto a riprap of brick on a heavy concrete base.
After impact, the unit is examined for deformation, rupture of parts,
damaged insulation, and any other openings into the interior of the
unit. When sufficiently cooled for handling the unit is inverted,
reheated for the time stated and allowed to cool without opening the
furnace doors. Once cooled, the unit is opened, dismantled and
examinations made regarding the heat insulating properties of the sample
such as usability of contents, condition of the interior finish,
security of locks, part fastenings and any signs of undue transmission
of heat or moisture.

(5) Humidity Test
After pre-conditioning, the unit is heated for 12 hours to obtain an
interior temperature of 70+or- 5°F and a relative humidity of 50 +or-
15 percent. The unit must successfully maintain an interior relative
humidity less than 85% during that part of the cooling period when the
interior temperature is above 120°F. Units are also examined for any
signs of moisture penetration into the interior.

(6) Combined
Explosion Hazard - Impact Test
A manufacturer may opt to combine and conduct both the Fire-Impact Test and the
Explosion Hazard Test on one sample fire
resistant safe or insulated record container as follows:
- The Explosion
Hazard Test is first conducted. If no explosion results during 30
minutes at 2000°F, the furnace temperatures are to be reduced to those
of the Standard Test Temperature Curve and the fire continued for an
additional 30 minutes for units to be rated 4 Hours, and for an
additional 15 minutes for units to be rated 2 Hours. No additional
exposure is required for units to be rated 1 Hour.
- After exposure to the
fire for the total period necessary for the classification desired, the
furnace fire is to be extinguished and the test sample withdrawn. Within
2 minutes, the unit is dropped from 30' into the riprap of brick on a
heavy concrete base, examined, reheated, and re-examined as per the
requirements of the Fire And Impact Test.
