EN 614-1 “Safety of machinery Ergonomic design principles Part 1: Terminology and general principles“ describes the principles

28、designers should adopt in order to take account of ergonomic factors. This European Standard describes how these principles should be applied to the design of access openings. This standard has been prepared to be a harmonized standard in the sense of the Machinery Directive and associated EFTA regu

29、lations. 1 Scope This European Standard specifies the dimensions of openings for access as applied to machinery as defined in EN 292-1. It provides the dimensions to which the values given in EN 547-3 are applicable. Values for additional space requirements are given in annex A. This European Standa

30、rd has been prepared primarily for non-mobile machinery, there may be additional specific requirements for mobile machinery. Dimensions for access openings are based on the values for the 95 thpercentile, whereas reach distances are based on the values for the 5 thpercentile, in each case the least

31、favourable body dimension of the expected user population being used as a basis. The same considerations apply to the location of access openings. The anthropometric data given in EN 547-3 originate from static measurements of nude persons and do not take into account body movements, clothing, equip

32、ment, machinery operating conditions or environmental conditions. This European Standard shows how to combine the anthropometric data with suitable allowances to take these factors into account. Situations where people are to be prevented from reaching a hazard are dealt with in EN 294. 2 Normative

33、references This European standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any o

34、f these publications apply to this European Standard only when incorporated in it by amendment or revision. For undated references the latest edition of the publication referred to applies.

Therefore, before installing access openings other options should

37、 be considered, e.g. possibility to open machinery, withdrawal of parts for repair. This is particularly important where the task demands frequent access. When access openings cannot be avoided the following criteria are of particular significance: a) Ease of access is influenced by: The demands of

38、the task, e.g. posture, nature and speed of movement, lines of sight, application of force; The location of the access opening relative to the position of the person, e.g. convenient height above floor, within easy reach, sufficient space outside to allow adoption of a comfortable posture, sufficien

39、t space inside to allow performance of the task; Frequency and duration of task; Whether tools are being carried, e.g. for maintenance or repair purposes; Length of access openings e.g. through a relatively thin wall (wall of a vessel) or through a channel type opening; Whether additional equipment

40、such as personal protective equipment (including protective clothing), or portable lighting, is being carried or worn; The type of clothing, e.g. light or heavy clothing, bare hands or thick gloves, bare headed or wearing a helmet; b) Environmental conditions (e.g. darkness, heat, noise, moisture);

41、c) Level of risk during the task. Therefore, in addition to the anthropometric data in each case, allowances shall be provided for the respective opening dimensions and reach distances, taking into account the above criteria. The applications on how to apply this European Standard in practice is con

42、tained in Annex A concerning allowances and in Annex B concerning position of access openings. Annex C gives information on the use of notations for dimensions and anthropometric measurements. 4 Access openings An access opening is an opening through which a person can lean forward, reach forward, o

43、r extend the upper body, head, arm, hand, a finger or several fingers, leg or foot, to be able to carry out measures during work procedures, such as operating of control actuators, repair duties or monitoring of processes or displays. This European Standard does not specify optimum dimensions, but m

44、inimum dimensions for the size of the opening and maximum dimensions for reach. Wherever possible, the basic dimensions for the openings should be increased, and the maximum dimensions for reach should be decreased.
