The "burn test" is a very poor indicator of PCBs. Mixtures that contain
non-PCB oil mixed with PCBs still tend to burn. I have had about 4
transformers i've tested that were negative on the burn-test, but positive
on the chemical test.
Especially since the "level at which people start paying serious
attention" is something like 50 ppm.
