Abstract
If a solid material of large surface area is contaminated with a liquid with a propensity to low-temperature thermal oxidation (most often oil high in unsaturated fatty acids), under certain conditions it can self-ignite. To identify the tendency to self-ignition of substances, there have been developed a number of methods, such as differential Mackey test, or recommended the use of other classical methods of thermal analysis, which however are not suited for the analysis of samples of larger volume. DTA and ARC appear to be among the best methods of thermal analysis, for the evaluation of dynamic and kinetic parameters of the process of self-heating of such samples
