ATEX Directive If you design, manufacture or sell any equipment or protective system intended for use in potentially explosive atmospheres, you must comply with the ATEX Directive 94/9/EC and the CE Marking Directive to market those products in the European Union (EU). This directive covers equipment and protective systems, which may be used in hazardous areas created by the existence of flammable gases, vapors, mists or dusts. It also covers electrical and non-electrical equipment. NEMA Ratings In non-hazardous locations, there are several different NEMA ratings for specific enclosure "types", their applications, and the environmental conditions they are designed to protect against, when completely and properly installed.
