BS EN 1005-3:2002+A1:2008EN 1005-3:2002+A1:2008 (E) 4 Introduction Within the life cycle of a machine from construction to dismantling, various machine-related actions require muscular force exertion. Muscular force exertion causes strain to the musculo-skeletal system. Unfavourable mus

25、culo-skeletal strain corresponds to the risk of fatigue, discomfort and musculo-skeletal disorders. The manufacturer of a machine is in a position to control these health risks by optimising the required forces, while taking into account the frequency, duration and variation of force exertion. The c

26、alculation procedure and the recommended limits in this standard aim to reduce the health risk for the operator as well as to increase the flexibility and possibility for a larger population to operate the machines which increases efficiency and profitability. This standard has been prepared to be h

27、armonised standard in the sense of the Machinery Directive and associated EFTA regulations. This standard is written in conformity with EN 1050 and gives the user hazard identification for harm through musculo-skeletal disorders and tools for qualitative and, to an extent, a quantitative risk assess

28、ment. The tools for the risk assessment also implicate how to do the risk reduction. This standard does not deal with risks connected to accidents. The recommendations provided by this standard are based on available scientific evidence concerning the physiology and epidemiology of manual work. The

29、knowledge is, however, scarce and the suggested limits are subject to changes according to future research. In accordance with the rules for CEN/CENELEC-standards Part 2, 4.9.3, European Standards are reviewed at intervals not exceeding five years. This European Standard is a type B standard as stat

30、ed in EN 1070. The provisions of this document can be supplemented or modified by a type C standard. NOTE For machines which are covered by the scope of a type C standard and which have been designed and built according to the provisions of that standard, the provisions of that type C standard take

31、precedence over the provisions of this type B standard. 1 Scope This European Standard presents guidance to the manufacturer of machinery or its component parts and the writer of C-standards in controlling health risks due to machine-related muscular force exertion. This standard specifies recommend

32、ed force limits for actions during machinery operation including construction, transport and commissioning (assembly, installation, adjustment), use (operation, cleaning, fault finding, maintenance, setting, teaching or process changeover) decommissioning, disposal and dismantling. The standard appl

33、ies primarily to machines which are manufactured after the date of issue of the standard. This standard applies on one hand to machinery for professional use operated by the adult working population, who are healthy workers with ordinary physical capacity, and on the other hand to machinery for dome

34、stic use operated by the whole population including youth and old people. The recommendations are derived from research on European population. This document is not applicable to specify the machinery which are manufactured before the date of publication of this document by CEN. BS EN 1005-3:2002+A1

EN 1070, Safety of machinery Terminology. 3 Terms and definitions For the purposes of this European Standard, the terms and definitions g

38、iven in EN 614-1, EN 1005-1:2001 and EN 1070 apply. 4 Recommendations 4.1 General recommendations and information The manufacturer should first consider EN 292-2:1991, annex A and EN 614-1 and EN 614-2 and then use the procedure for determining force limits presented below. It is crucially important

39、 that the operator is in control of the operation sequences and the pace of the machinery. Furthermore, machines shall be designed in a way so that actions demanding force exertion can be performed optimally with respect to the posture of body and limbs and the direction of force application. In add

40、ition machines shall be designed to allow for variations in movements and force exertions. The risk assessment procedure conveyed by this standard should formally be carried out for each action occurring during handling of the machinery. It may be noted, however, that infrequently occurring actions

41、with low force demands may be assessed on an overview base. Actions related to the handling of control actuators are considered in EN 894-3, however the present standard provides additional important information related to physical capacity and safety of the operator. 4.2 Risk assessment of action f

42、orces The risk assessment in the present standard is based on the force generating capacity of the intended users, and follows a three-step procedure as illustrated in Figure 1. In step A, the maximal isometric force generating capacity is determined for relevant actions within specified intended us

43、er populations. Within the scope of this standard the determination of maximal forces can be carried out according to three alternative methods. In step B, the force generating in step A capacity is reduced, according to the circumstances under which the force is to be generated (velocity, frequency

44、 and duration of action). The reduction is achieved by a set of multipliers. Basically, the output is a force that may be delivered without substantial fatigue. In step C, the risk associated with the intended use of the machinery is assessed. The risk evaluation is accomplished using risk multiplie

45、rs, reducing the maximal attainable force from step B to values associated with different levels of risk. The risk assessment focuses on musculo-skeletal disorders, and is preferentially based on the assumption that decreasing fatigue during work is effective in reducing disorders. BS EN 1005-3:2002

46、+A1:2008EN 1005-3:2002+A1:2008 (E) 6 The recommended force limits are applicable to most men and women in a general population in optimal action posture and under ideal circumstances. The limits are calculated for an optimal range of motion of the joints involved in the respective actions. It is rec

47、ommended to let force limits for professional users correspond to the 15 thpercentile of the whole adult population, i.e. males and females between 20 years and 65 years of age. Force limits for machines intended for domestic use should correspond to the 1 stpercentile of the same adult population.

48、The adult population is used as reference since reliable force data are scarce or unavailable for youth and aged individuals. Limits established by the procedure in this standard will essentially reduce hazards for at least 85 % of the intended user population. The manufacturer should be aware that

49、the force evaluation presented by the standard may be used also as a guidance when making instructions for the use of the machinery.
