| Test Panel: |
14"x14"x1/8" aluminium sheet |
| |
| Thermal Couples: |
Thermal Couples (TC) 2, 3 and 4 firmly fixed
to cool side of aluminum panel in centered 6" circle to measure
temperature of panel. TC 6 suspended on heat side of panel, tight
to panel, directly in front of heat source to measure heat applied
to surface of panel. |
| |
| Heat Source: |
250,000 BTU propane flame applied directly
to surface of panel. |
| |
| Treated Panel: |
One coat of red oxide primer followed by three
spray coats of FBI paint, approximate coating thickness of 21mil. |
| |
| Results: |
Untreated (bare) panel was completely destroyed
in under 18 minutes with gradual temperature increase as noted in
graph.
Treated panel had heat applied as noted in graph under identical
setup as untreated panel. Test was conducted for 2 hrs and 15 minutes
at which point it was discontinued. The panel temperature never
reached 400 ° F as noted in graph. |
