The intent of this technical note is approach to the user to the ATEX normative. For this we will begin defining, what is an explosive atmosphere, what is ATEX, as well as the directives that apply, uses and the implementation phases. Also we will make an explanation of the zones and the ATEX product marking. To finish with some examples of hazardous locations and examples of load cells and junction boxes we have available ATEX certified.
