Lab activity

The laboratory performs scientifi c and educational activities and testing of commercial explosives, the initial system and initiating devices, pyrotechnic products for entertainment and technical purposes as well as other explosive materials. The laboratory is accredited in accordance with the requirements of HRN EN ISO/IEC 17025:2007 for 27 test methods, while conducting tests according to a series of methods outside the scope of accreditation. The laboratory, in cooperation with the Agency forpotentially explosive atmospheres, operates within the national body in charge with the assessment of civil explosives and pyrotechnic products with the regulations of the European Commission. The activity takes place in the laboratory facilities at the Faculty of Mining, Geology and Petroleum Engineering, and the two outside testing laboratory-polygons.
