The products concerned and the extent to which hazards are covered are indicated in the scope of this standard. While producing this standard it
28、was assumed that: negotiations occur between the manufacturer and the purchaser concerning particular conditions for the use and places of use for the machinery related to health and safety; only suitably trained persons will operate this machinery; the machinery will be kept in good repair and work
29、ing order, in accordance with the manufacturers instructions, to retain specified health and safety characteristics throughout its working life; the place of installation is adequately lit. the place of installation will allow safe use of the machinery; by design of the load bearing elements, the sa
30、fe operation of the system and components is assured for loading ranging from zero to 100 % of the rated capacities and during testing; all parts of the machinery without specific requirements, will be: a) made from materials of adequate strength and durability and of suitable quality for their inte
31、nded purpose; b) of sound mechanical construction; c) designed in accordance with the usual engineering practice and engineering codes, taking account of all failure modes and incorporating appropriate safety factors. EN 617, EN 618 and EN 741 need to be considered for a complete continuous handling
32、 system (machine). BS EN 620:2002+A1:2010EN 620:2002+A1:2010 (E) 5 1 Scope 1.1 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
33、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. 1.2 This standard applies to use in ambient air temperatures of -15 C to + 40 C. 1.3 This standard does not
34、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 pha
35、rmaceuticals; 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
36、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 hand
37、led; 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
38、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. NOTE Directive 94/9/EC concerning equipment and protective systems intended for use in potentially explosive atmospheres can be applica
39、ble to the type of machine or equipment covered by this European Standard. The present standard is not intended to provide means of complying with the essential health and safety requirements of Directive 94/9/EC.
