DANISH TECHNOLOGICAL INSTITUTE The Danish Technological Institute is a self-owned and not-f-profit institution. We develop, apply and disseminate research- and technologically-based knowledge f the Danish and International business sects. As such, we participate in development projects, which are of use to society in close collabation with leading research and educational institutions both in Denmark and abroad. ATEX Certification Danish Technological Institute s department Certification & Inspection is an independent accredited Notified Body ExNB f electrical and none-electrical equipment Ex-equipment. Within the scope of our Notified Body no. 0396 we issue the following certificates in accdance with Directive 04/34/EU: EU Type Examination Certificate to Annex III (Module B) EU Unit Verification Certificate to Annex IX (Module G) EU Product Verification to Annex V (Module F) Internal Production Control to Annex VIII (Module A) Equipment f use in flammable atmospheres Directive 04/34/EU Concerning the ATEX Quality modules (PQAN) we issue the below listed certificates through DANCERT under the ExNB no. 073.

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 popularly 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 04/34/EU 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.

Equipment and protective systems intended to f use in relation with unstable chemical substances. Equipment intended to f use 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.
