Potentially explosive atmospheres generated by the raw materials used, intermediate / final products or the resulting waste may form in all industries involving flammable / combustible substances. Thecreation of these atmospheres must be treated as a major risk, as the fires or explosions that may occur affect human health and safety as well as the environment. Reducing these risks requires the assessment of the risk of explosion and the establishment of measures to reduce it to acceptablelevels in accordance with the requirements of European standards and the ATEX Directive.The general standard SR EN 60079-0 requires that only electrical / non-electrical equipment, certified for safe use, be used in hazardous areas Ex, which must ensure an appropriate normal degree of protection through the outer casing, as this protection is a requirement basic explosion protection.The tests for determining the degree of protection were carried out in accordance with harmonized European requirements and in the area of high-performance stands in accordance with SR EN ISO / IEC 17025, and the validity of the test results was demonstrated by successful participation in interlaboratory competitions and test of laboratory competition.
