Re: Watching Paint Dry: Hypothesis Testing of Ignition Scenarios Involving Spontaneous Heating

Iodine number will not provide a means to evaluate if the relevant conditions will result in self-heating to thermal runaway.
One can use smaller-scale controlled temperature oven tests to ascertain the relevant variable needed to develop an ignition model for a specific set of conditions. Particle size, ratio of oil to substrate, packing density, insulation are a few of the relevant variables that may or may not produce self-heating to thermal runaway.
