Abstract
Different types of combustible dusts are used in industry. These dusts can cause an explosion. The wood industry works almost exclusively with combustible dusts. Assessment and evaluation of fire engineering dust parameters is a complex problem. One of the parameters is the dust resistivity according to the EN ISO/IEC 80079:20-2 standard. Dust resistivity according to this standard is the specific conductivity of the dust sample. Based on it, it is possible to determine the resistivity of conductive (Group IIIC) or non-conductive (Group IIIB) dust according to the standard. In the case of non-conductive dusts, it is possible to predict the danger of dust in industry (generation of static electricity) based on the size of the specific conductivity. The article deals with the conductivity of beech wood dust and is aimed at assessing the conductivity of this wood depending on the particle size from 0 µm to 180 µm.
