ATEX means( taken from the French): "ATmosphere EXplosive"
non sparking
atmospheric explosition
An ATEX certificate is needed to demonstrate that an equipment can be safely operated in a potentially explosive athmosphere created by the presence of flammable gas, vapour, mist or clouds of combustibe dust. ATEX certificates are issued only by European Notified Certification Bodies, such as PTB or DEKRA EXAM in Germany, CESI or IMQ in Italy, BASEEFA in UK and many others. The ATEX Certificate, officially known as "EC Type Examination Certificate", is issued following the examination of the equipment Technical File and testing, according to the relevant standards that are applicable for each specific type of explosion protection applied to the equipment, such as flameproof or dust proof containers, intrinsically safe electrical devices, etc. Once the ATEX certificate is obtained the manufacturer must also get form a Notified Body a certification of the production: it is a control of the manufacturing activities based on ISO 9001 and focused on the ATEX requirements of the product. The basis of ATEX certification is the European Directive 94/9/EC, you can find almost all official information here: http://ec.europa.eu/enterprise/atex/indexinfor.htm.
