ABSTRACT

The assessment of explosion-protected electrical equipment is based on the requirements of the ATEX 2014/34 / EU Directive through tests and verifications carried out according to harmonized standards (SR EN 60079-0) and the standard for the type of protection of the equipment) which include requirements for protection of equipment by flameproof enclosure.
Assessment of explosion-protected electrical equipment is carried out under the provisions of the ATEX Directive 2014/34 / EU through tests and checks carried out in accordance with harmonized standards (SR EN 60079-0 standard and appropriate for the type of protection of equipment) which include requirements for equipment protection by flameproof enclosures.
For the evaluation of explosion-protected characteristics of electrical equipment, the provisions of harmonized standards from the SR EN 60079 series are used. The standards SR EN 60079-0 (Explosive atmospheres. Part 0: Equipment. General requirements) and one or more of the standards containing the specific requirements for the type(s) of protection applied to equipment (ex. SR EN 60079-1 for the type of protection flameproof enclosure "d", SR EN 60079-7 for the type of protection increased safety "e", are used for performing the assessment. For evaluation of explosion-proof electrical equipment, these shall be also subjected to type tests.
In the standard SR EN 60079-0 are indicated the type tests to which all the explosion-proof electrical equipment shall be subjected and the order in which these tests shall be performed.

Keywords: flameproof enclosure, fan, engine, increased safety, electrical parameters, explosive atmosphere
