SCOPE OF THE ATEX GUIDE This document is a simple guide to the ATEX Directives, their ATEX 94/9/EC (also ATEX 100a) and ATEX 99/92/EC (also ATEX 137). The ATEX Directive 94/9/EC sets out the Essential Safety Requirements for products and protective systems intended for use in potentially explosive atmospheres and the respective conformity assessment procedures. The ATEX Directive 99/92/EC, on the other hand, defines minimum Protection concepts IECEx and ATEX. The table below lists the types of protection methods and basic concepts of protection according to ATEX and IECEx standards for electrical equipment that is to be operated or installed in hazardous areas.

There are four basic methods utilised to avoid uncontrolled ignitions - exclusion of the flammable substance, prevention of component sparks or hot surfaces, explosion quenching and energy limitation. Equipment protection by type of protection "n" Type of protection applied to electrical apparatus such that, in normal operation and in certain specified abnormal conditions, it is not capable of igniting a surrounding explosive gas atmosphere Definitions ATEX Category Equipment Protection Levels Typical Zone Suitability 0A place in which an explosive atmosphere is continually present 1 G GaEquip.
