ATEX DIRECTIVE AND CLASSIFICATION SYSTEM
Since 2003, manufacturers across the European Union (EU) have been obliged to comply with strict new EU directives governing safety
in explosive atmospheres. Called ATEX (from the French ATmosphères EXplosives), ATEX Directive 94/9/EC has an impact not only on
European manufacturers, but also on non-European makers of industrial equipment wishing to sell in Europe.
Two of the most common classication systems for hazardous locations are the NEC Division Classication system and the Zone
Classication system used by the European Union (EU) and the International Electrotechnical Commission (IEC).
Article 500 of the NEC also classies hazardous locations according to the properties of the ammable vapors, liquids or gases, or
according to the combustible dusts or bers that may be present and the likelihood that a ammable or combustible concentration
or quantity is present. Articles 505 and 506 of the NEC refer to zone classications. Refer to the Technical Information section of the
Specier’s Guide for specic denitions and additional information.
Hoffman’s ATEX enclosures are not intended for use in explosion-proof or flame-proof (Ex d) applications.
