What is Ex-equipment / areas? Electrical non-electrical equipment used in an area where there is a risk of presence of a flammable atmosphere (gas dust) - are popular called Exequipment equipment f use in Hazardous Areas Ex-equipment are typically used in places like: The chemical industry Oil refineries Off she installations (platfms) Filling stations Tunnels/ sewers/ drains Milling industry/ printing-house / painting industry Farmer s installations Mining industry Scope of the ATEX Directive 94/9/EC The Directive covers Electrical and Non-electrical equipment! Equipment : Machines, apparatus, instruments, fixed mobile devices, control components and so on. Protective systems : e.g. equipment that can stop delay an explosion Components : Essential parts f the safety but with no autonomous function. Safety control and regulation equipment intended to be used outside the Ex-area - but with a function that secures the safety in the Ex-area.

Example of Zone Classification (Filling Station) Exclusions from the ATEX Scope Medical devices intended f use in medical environment. Equipment and protective systems intended to be used in relation with unstable chemical substances. Equipment intended to be used in domestic and non-commercial environments where flammable atmosphere is only a result of accidents. Personal protective equipment covered by Directive 89/686/EEC. Seagoing vessels and mobile offshe units together with equipment on board such units. Means of transpt i.e. vehicles, trailers, planes used f transptation. (Vehicles used in potential explosive atmosphere are not excluded).

Zone 2 (gas) Zone 22 (dust) F these protection principles the Ex-protection technology is directly linked to the sensitivity of the surrounding gas this is not the case f the other Exprotection principles. Ex-Certification f the American Market Inflammable substances f all 3 Categies can be Gas, Vapours, Mist, Dust TÜV Denmark offers certification to the Nth American market f Zone 0, 1 and 2 and Class I, II and III, Division 1 and Division 2.
