DIN 53436-2:2015-12

This standard specifies a method for the thermal decomposition of materials for analytic-toxicological studies. The method can be used for the examination of thermal decomposition products. The sample thickness has been kept constant in the density range 0.4 kg/m<(hoch)3 so that samples with the same surface are available. For materials of much lower density, correspondingly larger sample volumes are required to obtain measurable effects. Here, samples of equal weight (corresponding to the mass occupancy of a substance of density 0.4 kg/m<(hoch)3) have been specified. In order to ensure that the surface area exposed to thermal decomposition is approximately the same even for meltable substances, the substances are tested in a cuvette. When comparing the results, the different sample shapes and quantities shall be taken into account.
