The paper-s purpose is to quantify the measurement consequences in the purge test of equipment protected with the -p- type of protection. In order to achieve this objective, the authors involved a simulation process for a pressurization enclosure. The simulation was conducted, in the first stage, without measurement to obtain a reference after that simulation was conducted for scenarios involving sampling separately for each measurement point. The first part of the paper presented the risks of explosion and pressu...

Directive 2014/34/EU ATEx regulates the placement on the European market of equipment and technical installations for use in potentially explosive atmospheres. The current work aims to describe the design and use of low current equipment in the development of industrial robots used for the inspection of hard-to-reach areas with explosion hazard. Documentation evaluation and testing of equipment with intrinsic safety -i- type of protection (SR EN 60079-11 Equipment protection by intrinsic safety "i") according the ...
