9、nternational Organization for Standardization) is a worldwide 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

10、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 electrotechnica

11、l standardization. International Standards are drafted in 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 bod

12、ies for voting. Publication as an International Standard 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

13、 or all such patent rights. ISO 16121-2 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 13, Ergonomics applicable to road vehicles. This second edition cancels and replaces the first edition (ISO 16121-2:2005), which has been editorially revised. ISO 16121 consists of t

14、he following parts, under the general title Road vehicles Ergonomic requirements for the drivers workplace in line-service buses: Part 1: General description, basic requirements Part 2: Visibility Part 3: Information devices and controls Part 4: Cabin environment BS ISO 16121-2:2011ISO 16121-2:2011(

15、E) ISO 2011 All rights reserved vIntroduction Poor ergonomics in the drivers workplace in buses designed to provide scheduled urban and interurban services increase the already high physical and mental strains on the driver. It is the aim of this part of ISO 16121 to supply the designer of line-serv

16、ice buses with information about how to develop an overall ergonomic concept for the drivers workplace. The recommended requirements on the drivers workplace for line-service buses made in this part of ISO 16121 are based on the scientific conclusions of the research project “drivers workplace in th

17、e line-service bus”. This was conducted in Germany and summarized in the VDV 2341 recommendation. Further comprehensive ergonomic studies related to the design of an enhanced driver workplace conducted in the United States, Canada, the Netherlands, Sweden and the United Kingdom 23456have been consid

18、ered and found to provide recommendations covering similar areas. This part of ISO 16121 sets out to consider the practical implications for all ranges of drivers but particularly those with statures from 1,55 m (small female) to 2,0 m (large male). These statures include shoes (30 mm). It is also e

19、ssential that the designer refers to the specifications and requirements of all parts of ISO 16121 (1 to 4) before completing the design of a drivers workplace. It should be noted that where there is also national legislation covering any of the subjects contained herein, then both should be complie

20、d with. However, if a contradiction between the two should arise in any specific area, then the legislation shall prevail for that specific point only.

21、for the drivers workplace in line-service buses Part 2: Visibility 1 Scope This part of ISO 16121 specifies the requirements for the drivers field of view to the area in front of the vehicle, to the entrance opposite the drivers seat and the interior compartment. It applies to the drivers workplace

22、in low-floor line-service buses designed for the carriage of passengers, comprising more than eight seats in addition to the drivers seat, and having a maximum weight exceeding five metric tonnes and an overall width exceeding 2,30 m. 2 Normative references The following referenced documents are ind

23、ispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. ISO 16121-1, Road vehicles Ergonomic requirements for the drivers workplace in line-service

24、 buses Part 1: General description, basic requirements 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 low-floor vehicle in which at least 35 % of the area available for standing passengers (or of its forward section in the case of an articul

25、ated vehicle) forms a single area without steps, reached through at least one service door by a single step from the ground 3.2 vision point V1 point 635 mm vertically above the H-point (as defined in ISO 16121-1) with the seat in its rearmost highest position within the required seat H-point adjust

26、ment range specified in ISO 16121-1 NOTE The V1 and V2 vision points, as defined in ISO 16121-2, can differ from V1 and V2 vision points defined in national and international regulations. 3.3 vision point V2 point 635 mm vertically above the H-point (as defined in ISO 16121-1) with the seat in its f

27、oremost lowest position within the required seat H-point adjustment range specified in ISO 16121-1 NOTE The V1 and V2 vision points, as defined in ISO 16121-2, can differ from V1 and V2 vision points defined in national and international regulations.

28、 All rights reserved4 Visibility 4.1 Forward blind spot 4.1.1 Requirement In order to reduce the blind spot immediately in front of the vehicle, the following requirement shall be met. A bar, having a length equal to the width of the vehicle, placed in front of the bus at a height of 1 100 mm above

29、the ground and 300 mm in front of the foremost surface (normally front face of the bumpers) shall be visible, either by direct or indirect view, from both positions V1 and V2 for a minimum of 95 % of its length (see Figure 1). When checking the requirement of this subclause, any obstruction caused b

30、y the steering wheel shall not be taken into account. If the above requirement cannot be met by direct vision either from V1 or V2, then an alternative device shall be provided to achieve this, such as a mirror or video system. 4.2 Lateral visibility 4.2.1 Requirement If there is a service door loca

31、ted at the front corner of the vehicle, a cube measuring 100 100 100 mm, positioned adjacent to the door at a height of 800 mm above the ground, shall be visible either directly or indirectly. 4.2.2 Testing procedure 4.2.2.1 Position the cube indicated in 4.2.1 alongside the foremost window in the s

32、ervice door at the front corner, with its lowest side positioned horizontally and at a height of 800 mm above the ground (see Figure 2). 4.2.2.2 Check that at least three-fourths of one face of the cube positioned as indicated in 4.2.2.1 is visible from the points V1 and V2 (according to 4.1.1). 4.2

33、.2.3 If the vehicle is fitted with an adjustable dashboard, the requirements of 4.1 and 4.2 shall be checked with the dashboard in its mid-position, as defined by the manufacturer. 4.3 View upwards To ensure sufficient view of traffic lights, etc., a minimum clear angle of view above V1 shall be pro

34、vided. There shall be unobstructed view through the windscreen, measured through a horizontal plane intersecting in V1 with a 15 inclined plane (see Figure 3). When checking this requirement, any obstruction caused by rear view mirror, windscreen wiper arms, split windscreen centre bar, video screen

35、s, sun blind or visor, drivers fan and any legally required marking shall not be taken into account. 4.4 View to passenger compartment Mirrors or other devices shall be provided for the observation of the following passenger compartment areas. Areas to be observed shall be: gangways; and entrance/ex

36、it zones, except within the drivers direct line of sight.
