11、nal 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 that committee. Internati

12、onal 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 accordance with the rul

13、es 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 requires approval by at

14、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 14401-1 was prepared by Technical Committee ISO/T

15、C 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 14401-1:2004), which has been technically revised. ISO 14401 consists of the following parts, under the general title Earth-movin

17、d rear-view mirrors fitted to certain earth-moving machinery. 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 m

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

42、 or C (see ISO 14401-2), an up to 205 mm light spacing is permissible. For surveillance mirrors, e.g. field-of-vision class D (see ISO 14401-2), an up to 405 mm light spacing is permissible. NOTE The left and right light bulbs can each be positioned so that the measurement provides a maximum field o

43、f vision. During this procedure, they do not have to be symmetric to the FPCP as long as the maximum distance from the FPCP is 102,5 mm or 202,5 mm, as appropriate. 7.2.3 To take measurements, rotate the light bar so that the line between the two light bulbs is perpendicular to the line between the

44、FPCP and the centre of the mirror. 7.3 Measurement of field of vision 7.3.1 The light source reflection from the mirror(s) fitted onto the machine defines the field of vision of the mirror(s). A hand-held test mirror can be used to recognize the light source reflection at the field of vision measuri

45、ng locations. The reflection in the hand-held test mirror shall be measured as close as possible at the ground level or at other heights as specified in ISO 14401-2. 7.3.2 For the assessment of the field of vision with respect to ISO 14401-2: adjust the mirror(s) so that measuring locations close to

46、 the machine can be verified using the hand-held mirror; without readjusting the mirrors, verify that, at the field of vision marked on the test surface according to 7.1.2, there is light source reflectance (see 5.4) from at least one of the light bulbs. 7.3.3 In all cases, mark and record the limit

47、s where light from at least one of the light bulbs can be seen on the test surface. 7.3.4 This measurement procedure may be used for assessing the field of vision of other mirrors fitted to the machine, i.e. surveillance mirrors fitted to overcome direct visibility maskings identified during the tes

48、ts according to ISO 5006. NOTE The test can be carried out in a dark environment where the outer and inner borderlines of the field of vision at the ground level can be directly determined. 8 Calculation and computer simulation procedure The measurement procedure described in Clause 7 may be simulat
