EMC tests standardization for mining equipment

The paper presents selected results of electromagnetic disturbance measurements recorded in working mine conditions. Attention has been brought to the most important phenomena which can be insufficiently reflected in the requirements of current EMC standards. The paper also refers to examples of potential lack of compatibility of mining equipment. The issues concern equipment produced by different manufacturers from Poland, Czech Republic, Slovakia, Germany and Belarus. The incompatibility issues confirmed in those pieces of equipment were later eliminated therefore the final products were free of them, but those observations point out at the scale of compatibility problems that occur in underground mines.
