The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committ

12、ee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechn

Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval

17、n This part of ISO 15534 is one of several ergonomics standards for the safety of machinery. EN 614-1 (2 in the Bibliography) describes the principles designers should adopt in order to take account of ergonomic factors. This part of ISO 15534 describes how these principles should be applied to the

18、design of access openings. This part of ISO 15534 is based on EN 547-2:1996 that was prepared as a harmonized standard conforming with the Machinery Directive and associated European Free Trade Association (EFTA) regulations.INTERNATIONAL STANDARD ISO 15534-2:2000(E) ISO 2000 All rights reserved 1 E

19、rgonomic design for the safety of machinery Part 2: Principles for determining the dimensions required for access openings 1 Scope This part of ISO 15534 specifies the dimensions of openings for access into machinery as defined in ISO/TR 12100-1. It provides the dimensions to which the values given

20、in ISO 15534-3 are applicable. Values for additional space requirements are given in annex A. This part of ISO 15534 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 t

21、he 95th percentile, whereas reach distances are based on the values for the 5th percentile, in each case the least 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 ISO 1

22、5534-3 originate from static measurements of nude persons and do not take into account body movements, clothing, equipment, machinery-operating conditions or environmental conditions. This part of ISO 15534 shows how to combine the anthropometric data with suitable allowances to take these factors i

23、nto account. Situations where people are to be prevented from reaching a hazard are dealt with in ISO 13852. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this part of ISO 15534. For dated references, subse

24、quent amendments to, or revisions of, any of these publications do not apply. However, parties to agreements based on this part of ISO 15534 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For undated references, the late

25、st edition of the normative document referred to applies. Members of ISO and IEC maintain registers of currently valid International Standards.

27、ach through minimum-access openings are likely to be less efficient, less safe and less healthy than working with unrestricted access. Therefore, before installing access openings other options should be considered, e.g. possibility to open machinery, withdrawal of parts for repair. This is particul

28、arly 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 the task, e.g. posture, nature and speed of movement, lines of sight, application of force, the loca

29、tion 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, sufficient space inside to allow performance of the task, frequency and duration of task, whether tools are b

30、eing 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, such as personal protective equipment (including protective clothing), or portable lighting, is be

31、ing 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); c) level of risk during the task. Therefore, in addition to the anthropometric data in each case,

32、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 part of ISO 15534 in practice are contained in annex A, concerning allowances, and in annex B, concerning the position of access openi

34、 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. See Figures 1 to 12. This part of ISO 15534 does not specify optimum dimensions, but minimum dimensions f

35、or 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.

47、ccording to ergonomic and safety and health principles. This part of ISO 15534 describes minimum dimensions for access openings based on anthropometric measurements, i.e. static measurements of nude persons. The opening dimensions, including allowances, in this part of ISO 15534 do not always take i

48、nto consideration, for example: aspects of health and safety arising from contact with the access opening itself; whether the body positions and movements that must be used in the access opening mean any risk to the users safety and health, e.g. in relation to how often or how long the person has to

49、 use the access opening; whether the person has to adopt a certain body position in order to meet the force demands of the task without becoming overloaded; the space required for transportation of equipment and tools through the access opening; the space required for using equipment and tools in the access opening in a proper ergonomic way, e.g. cleaning, repair and maintenance work; personal protective equipment the user might wear when reaching through the access opening;
