DIN EN 13821:2003-03

This EN specifies a method of test to determine the minimum ignition energy of a dust/air mixture by an electrically generated spark. It is intended that the dust be tested in a form representing conditions of actual use so that assessment of the hazard present can be made. This EN is applicable to the determination of the minimum ignition energy of a combustible dust dispersed in air, referred to hereafter as a 'dust/air mixture'.
