6 Declaration of conformity - Warnings Every product that complies with Directive 94/9/EC must be supplied with an EC declaration of conformity that must contain at least the following information: - Name or trademark and address of the manufacturer - Description of the equipment - Provisions to which the equipment complies - Name, identification number and address of the notified body - "Type EC" certificate number - Identification data of the signee binding the manufacturer or the EU representative - Reference to (if applicable): harmonised standards, technical specifications used and other EU directives applied If the conformity procedures stated in the directive do not require the participation of a notified body (Group II, category 3 equipment), in the EC declaration of conformity there will be no reference to a notified body or to the "EC type" certificate. Instructions for use are very important because their correct application is a necessary condition to ensure the observance of the essential health and safety requirements (EHSR). Therefore, the instructions for use must detail the operations that must be carried for a safe execution of the following: correct use (zone, environmental conditions, reference to safety signs, etc.); correct operation (forbidden, specific or limited conditions of use, if applicable); correct installation and/or adjustment; commissioning; correct maintenance; installation and/or replacement of components. Classification of potentially explosive areas in accordance with standards EN 60079-10-1 and EN 60079-10-2 Zones 2 and 22 are defined as follows in Directive 99/92/EC: Zone 2 - Area in which during ordinary activities an explosive atmosphere consisting in a mixture of air and flammable substances in the form of gas, vapour or mist, is unlikely to form and, when this does, it is for a short period of time only. Zone 22 - Area in which during ordinary activities an explosive atmosphere consisting in a cloud of combustive dust is unlikely to form and, when it does, it is for a short period of time only. Zones, groups and product categories are divided as follows: In Zones 0, 1, 20 and 21 only electrical equipment with an EX certification issued by third parties can be used. In Zone 0, it is however only possible to use equipment that has been specifically approved for use in this zone. In Zones 2 and 22, it is possible to use electrical equipments that comply with the main safety requirements of ATEX Directive 94/9/EC and for which the manufacturer has issued a certificate of conformity. For more detailed information, refer to the integral text of the two directives and to the Implementation Guidelines of the directives available on the European Union website, in addition to the law provisions in force in the member states, which may differ in terms of applicable sanctions. For technical information concerning the design and manufacture of equipment, refer to the harmonised standard in force, which is continuously being amended and updated. The following section provides general information on the classification of ATEX areas where combustive dust is present. Classification of ATEX areas where combustive dust is present The classification of these areas is based on the same approach used for explosive atmospheres where gases are present. However, the assessment of these areas is more direct because of the relatively consistent behaviour of the different types of dust, which is less varied as compared to the behaviour of flammable gases, vapours and mists. An explosion of dust produces a rapid combustion, which releases energy in the form of heat and overpressure. The conditions that may lead to the formation of a potentially explosive atmosphere can be summarised as follows: l Dust must be combustive l Dust must be dispersed in air l The granulometry of dust must permit the propagation of flames l The concentration of dust must fall within the so-called flammability limit l An ignition source with sufficient energy must be present l A sufficient amount of combustive agent (oxygen) must be present to enable combustion Classification of areas Description Gas Dust ZONE 0 ZONE 20 Area in which the explosive atmosphere is permanent, present for long periods of time or frequent ZONE 1 ZONE 21 Area in which the explosive atmosphere is occasionally present during the ordinary use of equipment ZONE 2 ZONE 22 Area in which the explosive atmosphere is unlikely to form during the ordinary use of equipment and, if present, persists for a short period of time only Flammable material Zone (Directive 99/92/EC) Group (Directive 99/92/EC) Category (Directive 99/92/EC) Methane, dust Mining industry I M1 Mining industry I M2 or M1 Gases, vapours Zone 0: permanent, long-term or frequent explosive atmosphere II 1G Zone 1: occasionally explosive atmosphere II 2G or 1G Zone 2: explosive atmosphere that is unlikely to form or that persists for short periods of time II 3G or 2G or 1G Dust Zone 20: permanent, long-term or frequent explosive atmosphere II 1D Zone 21: occasionally explosive atmosphere II 2D or 1D Zone 22: explosive atmosphere that is unlikely to form or that persists for short periods of time II 3D or 2D or 1D
