Howdy all,
I'm reviewing a test plan to replace a P-seal on an aluminum air-oil heat exchanger. It's calling for a 2000 deg flame for 5 minutes to show fire resistance. I don't think a fluorosilicone/glass fiber P-seal would survive 5 minutes at 2000 degrees and I wanted a sanity check to see if we're specifying the right test. This P-seal is on the inlet side of the air circuit. This has to go through a DER, but I don't want to shoot myself in the foot by specifying a test that we won't be able to pass and isn't really needed.
Thanks,
-Kirby

Remember, first define the problem, then solve it.
