APPENDIX A
DETAILED DESCRIPTION OF TEST 1
First Test
Nine containers of various types were positioned around the periphery of a wood crib fire to
determine if radiant heat would cause ignition. Also, the protection afforded by placing
plastic material in steel containers was examined.
The following containers were used in the test:
1. A 52 by 52 by 30-inch plywood container with a built-in pallet and a polyurethane
foam insert (6.5 x 106 Btu).
2. A 30-gallon stainless steel drum filled with foamed polystyrene packing material
(1.75 x 105 Btu).
3. A 37 by 20-inch-diameter fiberboard drum with a polyurethane foam insert
(1.156 x 106 Btu).
4. A 30-gallon steel drum lined with Celotex and a polyurethane foam insert
(5.02 x 105 Btu).
5. A 42 by 23-inch-diameter fiberboard drum with a polyurethane foam insert
(1.013 x 106 Btu).
6. A 30-gallon steel drum filled with polyurethane foam (1.96 x 106 Btu).
7. Press-formed polystyrene foam containers, 14 inches square and 3 inches deep
(2.4 x 105 Btu).
8. A 30 by 30 by 14-inch polyester-reinforced Fiberglas container with polyurethane foam
buns (2.79 x 105 Btu).
9. A 40 by 18-inch cardboard box with a polyurethane insert (2.473 x 106 Btu).
All containers were placed four feet from the edge of the crib fire.
Thermocouples were placed on the face, inside, and back side of some of the containers to
determine the radiant heat temperatures. The location of the thermocouples is shown in
Figure A-1.
Approximately five minutes after igniting the wood crib, a maximum temperature of
1,0100 C was reached in the crib. None of the containers ignited although some
deformation of the press-formed polystyrene containers was noted because of melting.
However, the temperature at this point did not allow hand contact. Some "steaming" of the
