National foreword This standard includes safety requirements. This standard has been prepared
5、by Technical Committee CEN/TC 148 “Continuous handling equipment and systems Safety” (Secretariat: AFNOR, France). The responsible German body involved in its preparation was the Normenausschuss Maschinenbau (Mechanical Engineering Standards Committee), Working Committee NA 060-22-31 AA Stetigfrdere
6、r of Section Frdertechnik. Representatives of manufacturers and users of continuous handling equipment, and of the employers liability insurance associations contributed to this standard. This standard contains specifications meeting the essential requirements set out in Annex I of the “Machinery Di
7、rective”, Directive 2006/42/EC, and which apply to machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of the directive. Once this standard is cited in the Official Journal of the E
8、uropean 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”). The European Standards referred to in this document have been published as the corresponding DIN E

The products concerned and the extent to which hazards are covered are indicated in the scope of this standard. While producing this standard it was assumed
34、 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 working order,
35、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 safe operatio
36、n 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 intended purpos
37、e; 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 system (ma
38、chine). DIN EN 620:2011-07 EN 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 3.1 to 3.2.4 a
39、nd 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 cover: a) use
40、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;
41、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 speci
42、fic 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) hazard
43、s 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 e
44、quipment. 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 applicable to the typ
45、e 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.
