The scientific paper presents the synthesis of research results undertaken to develop the technical and methodological infrastructure for assessing the safety of means of initiating explosives, on the abrasion resistance of rheophores of electric detonators, in order to increase the safety of their use. The state-of-the-art OPVA 10 equipment is used to test the ability of rheophores insulation to withstand the abrasion forces that may occur during normal use. This equipment with a programmable automatic ensures the testing of the rheophores of the electric detonating staples to determine the abrasion resistance under the operating conditions provided by the harmonized European standard EN 13763-4 and the technical specification of the manufacturer, the operating temperature of this equipment being between 10 ÷ 30 °C ensuring at the highest level the fulfillment of the technical requirements imposed by the European and international regulations in the field.
