This standard contains specifications giving detail to the essential requirements of the EU ATEX Directive 94/9/EC and those requirements EU Machinery Directive 2006/42/EC which apply to machines that are either first placed on the market or commissioned within the European Economic Area (EEA) to facilitate proof of compliance with these requirements. Once this standard is cited in the Official Journal of the European Union, it is deemed a "harmonized" standard and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive ("presumption of conformity"). This European Standard applies to self-propelled and pedestrian propelled manual and semi-manual industrial trucks as defined in ISO 5053-1 including their load handling devices and attachments (hereafter referred to as trucks) intended for use in potentially explosive atmospheres. Attachments mounted on the load carrier or on fork arms which are removable by the user are not considered to be a part of the truck. This European Standard specifies supplementary technical requirements for the prevention of the ignition of an explosive atmosphere of flammable gases, vapours, mists or dusts by industrial trucks of equipment group II and equipment category 2G, 3G, 2D or 3D. The relationship between an equipment category (hereafter referred to as category) and the corresponding zone (area classification) is shown in informative Annex B. This European Standard does not include: - trucks of equipment group I; - trucks of equipment group II, equipment category 1; - trucks intended for use in potentially explosive atmospheres with hybrid mixtures; - protective systems. This European Standard is not applicable to trucks intended for use in potentially explosive atmospheres of carbon disulphide (CS2), carbon monoxide (CO) and/or ethylene oxide (C2H4O) due to the special properties of these gases. This standard contains the German version of EN 1755:2015 which has been prepared by Technical Committee CEN/TC 150 "Industrial trucks - Safety" at the European Committee for Standardization (CEN). This standard differs from DIN EN 1755:2013-08 as follows: a) some structural amendments; b) technical changes. The national interests during the preparation were represented by Committee NA 060-22-42-01 AA "Ex-Schutz von Flurförderzeugen" ("Potentially explosives atmospheres") in Technical Section "Fördertechnik" ("Conveying technology") of DIN Standards Committee Mechanical Engineering (NAM). Representatives of the manufacturers and users of industrial trucks, and of the employers' liability insurance associations were involved in the preparation.
