TY - JOUR A1 - Spitzer, Stefan A1 - Krietsch, Arne A1 - Jankuj, Vojtech T1 - Experimental Parameter Study and Inherent Scattering of Safety Characteristics of Dusts JF - Chemical engineering transactions N2 - Safety characteristics are widely used in industrial processes to avoid explosive atmospheres (primary explosionprotection) or to mitigate the consequences of an explosion (constructive explosion protection). Several laboratory parameters influence the determined values when performing the test series such as the beginning pressure and the pre-ignition pressure rise, the ignition source, the ignition energy, the burning duration and volume or the concentration of the combustible substance. In the different standards for the determination of safety characteristics of dusts there is no statement about the scattering or the deviation when parameters are chosen or occur on the borders of their allowed range. Thus, two laboratories might determine values that are hardly comparable for the same given substance. This article summarizes some of the influential factors that cause a deviation and shows the inherent scattering of dust tests when all other parameters are kept constant. It also provides some advice how to minimize the deviation and the scattering with little effort.
