This document deals with the technical requirements for stationery belt conveyors and systems as defined in 3.1 to 3.2.4@ for designed for continuously conveying loose bulk materials. The covered phases of life cycle are design@ setting@ operation@ maintenance and cleaning. Requirements for electromagnetic compatibility are also covered. This document does not give the additional requirements for: a) use in coal mining and open cast lignite mining; b) use for man-riding; c) floating@ dredging and ship mounted structures supporting the conveyor; d) biological and chemical hazards resulting from handling foodstuffs or pharmaceuticals; e) the design of the supporting structure which is not part of a conveyor; f) the effects of wind; g) hazards resulting from handling specific hazardous materials@ (e.g. explosives@ radiating material); h) hazards resulting from contact with or inhalation of harmful fluids@ gases@ mists@ fumes or dust; i) biological and micro-biological (viral or bacterial) hazards; j) hazards due to heat radiation from the materials handled; k) hazards caused by operation in electromagnetic fields outside the range of EN 61000-6-2:2005; l) hazards caused by operation subject to special regulations (e.g. explosive atmospheres); m) hazards caused by the use of ionising radiation sources; n) conveyors using a moving belt with other than a continuous rubber or polymeric surface for the conveying medium. The safety requirements of this standard apply to equipment and systems placed on the market after the date of publication of this standard. NOTE Directive 2014/34/EC concerning equipment and protective systems intended for use in potentially explosive atmospheres can be applicable to the type of machine or equipment covered by this European Standard. The present standard is not intended to provide means of complying completely with the essential health and safety requirements of Directive 2014/34/EC.
