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.
