arcniz,
Of course it wouldn't be an 'imaginary test'.
I'm suggesting that real oil is cooked in the pack in flight and the air is then sampled.
Perhaps University research is the way ahead but they seem to take for ever to reach conclusions and then their findings seem to be quietly ignored in the absense of any actual wreckage.
Politicians always seem to go by 'independent reports' and I guess that's what you've got to do here, try and introduce some independence.
I wouldn't trust the manufacturers one inch.
Lets face it, inconvenient findings would be incredibly damaging for the industry and have enormous repercussions, so they would not be in too much of a rush to find the truth.
