11、wide federation of national standards bodies (ISO member bodies). 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 committee has been established has the right to be represented on t

12、hat 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 electrotechnical standardization. International Standards are drafted in

13、 accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard

14、requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 14401-2 was prepared by T

15、echnical Committee ISO/TC 127, Earth-moving machinery, Subcommittee SC 1, Test methods relating to safety and machine performance. This second edition cancels and replaces the first edition (ISO 14401-2:2004), which has been technically revised. ISO 14401 consists of the following parts, under the g

16、eneral title Earth-moving machinery Field of vision of surveillance and rear-view mirrors: Part 1: Test methods Part 2: Performance criteria BS ISO 14401-2:2009ISO 14401-2:2009(E) iv ISO 2009 All rights reservedIntroduction This part of ISO 14401 gives performance criteria for surveillance and rear-

17、view mirrors fitted to certain earth-moving machinery. The field of vision described is intended to define the minimum visibility area behind the machine in order to provide adequate visibility for the operator when working around other moving machines during operation in a forward/reverse mode or d

18、uring transport on roadways with other traffic. As specified in ISO 5006, mirrors may also be fitted on earth-moving equipment to help meet the visibility performance requirements of ISO 5006 when those requirements cannot be met by direct visibility alone. The testing procedures for mirrors in ISO

19、14401-1 and in ISO 5006 have been aligned to allow a mirror to fulfil the requirements of both ISO 5006 and this part of ISO 14401. Mirrors can also be fitted for the purpose of compliance with national or local regulations, e.g. on-road requirements. BS ISO 14401-2:2009INTERNATIONAL STANDARD ISO 14

20、401-2:2009(E) ISO 2009 All rights reserved 1Earth-moving machinery Field of vision of surveillance and rear-view mirrors Part 2: Performance criteria 1 Scope This part of ISO 14401 specifies criteria for the field-of-vision performance of surveillance and rear-view mirrors on earth-moving machinery.

21、 It is applicable to the ride-on machines of the machine families and sizes listed herein (see Annex A), used both on and off public roads. NOTE 1 For machines not listed in Annex A, the criteria of similar machine types and/or sizes can be used as guidance for the fitting of optional mirrors to the

22、se machines. NOTE 2 Additional national road regulations can apply for machines travelling on public roads. 2 Normative references The following referenced documents are indispensable for the application of this document.

BS ISO 14401-2:2009ISO 14401-2:2009(E) 2 ISO 2009 All rights reserved4 Classification of fields of vision The fields of vision are classified as follows. Class A: field of vision as specified

26、in 5.4.2 and shown in Figure 1. Class B: field of vision as specified in 5.4.3 and shown in Figure 2. Class C: field of vision as specified in 5.4.4 and shown in Figure 3. Class D: field of vision as specified in 5.4.5 and shown in Figure 4. 5 Requirements 5.1 General Mirrors and their mounting shal

27、l meet the following requirements. a) Earth-moving machinery according to Annex A shall be equipped as appropriate with a mirror or mirrors conforming to the corresponding field of vision class(es). b) Mirrors shall be installed so as to minimize the effect of vibration during conditions of intended

28、 use as specified by the manufacturer. c) Part or parts of the rear end, left and right of the machine, shall be visible to the operator by means of a mirror or mirrors. Alternatively, closed circuit television cameras (CCTV) may be used to achieve the required fields of vision. 5.2 Mirror positions

29、 The following is applicable. a) If equipped with a cab, exterior rear-view mirrors shall be visible through the portion of the windscreen that is swept by the windscreen wiper or through the side windows. If equipped with a canopy, exterior rear-view mirrors shall be visible through openings in the

30、 canopy. b) A rear-view mirror should not project laterally beyond the outer contour of the machine by more than is necessary to obtain the field of vision specified in 5.4. For machines intended to be used on the road, mirrors that project laterally by more than 0,20 m from the machine (and install

31、ed more than 2 m above ground level) shall be of the foldable type so that they can easily be put back in position if knocked out of alignment. c) Where the bottom edge of an exterior rear-view mirror is less than 2 m above ground level, the mirror shall not project more than 0,3 m beyond the overal

32、l width of the machine.
