This European standard deals with the technical requirements to minimise the risks due to the hazards listed in clause 4, which can arise during operation and maintenance of fixed belt conveyors and systems as defined in 3.1 to 3.2.4 and designed for continuously conveying loose bulk materials from the loading point(s) to the unloading point(s). Requirements for electromagnetic compatibility are also covered.1.2This standard applies to use in ambient air temperatures of -15 °C to + 40 °C.1.3This standard does not cover:a)use in open cast lignite mining or use underground, such as in mines or tunnels;b)use in public areas or for man-riding;c)floating, dredging and ship mounted equipment;d)conveyors requiring a high level of cleanliness for hygiene reasons, e.g. in direct contact with foodstuffs or pharmaceuticals;e)conveyors using a moving belt with other than a continuous rubber or polymeric surface for the conveying medium;f)transportation of the conveyor;g)the design of the supporting structure which is not part of a conveyor (see 3.2);h)the effects of wind;i)hazards resulting from handling specific hazardous materials, (e.g. explosives, radiating material);j)hazards resulting from contact with or inhalation of harmful fluids, gases, mists, fumes or dust;k)biological and micro-biological (viral or bacterial) hazards;l)hazards due to heat radiation from the materials handled;m)hazards caused by operation in electromagnetic fields outside the range of EN 61000-6-2: 1999;n)hazards caused by operation subject to special regulations (e.g. explosive atmospheres);o)hazards caused by noise;p)hazards caused by the use of ionising radiation sources;q)hazards caused by hydraulic equipment.The safety requirements of this standard apply to equipment and systems placed on the market after the date of publication of this standard.
