10、tandards 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. International
11、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 rules gi
12、ven 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 least
13、 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 16121-4 was prepared by Technical Committee ISO/TC 22,
14、 Road vehicles, Subcommittee SC 13, Ergonomics applicable to road vehicles. This second edition cancels and replaces the first edition (ISO 16121-4:2005), which has been editorially revised. ISO 16121 consists of the following parts, under the general title Road vehicles Ergonomic requirements for t
15、he 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 16121-4:2011ISO 16121-4:2011(E) ISO 2011 All rights reserved vIntroduction Poor ergonomics in the drivers workplace
16、 in buses designed to provide scheduled urban and interurban services increase the already high physical and mental strains on the drivers. It is the aim of this part of ISO 16121 to supply the designer of line-service buses with information about how to develop an overall ergonomic concept for the
17、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 the line-service bus”. This was conducted in Germany and summarized in the recommendati
18、on VDV 2341. 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 Kingdom23456have been considered and found to provide recommendations covering similar areas. This part of ISO 161
19、21 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 essential that the designer refers to the specifications and requirements of all parts
20、 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 complied with. However, if a contradiction between the two should arise in any specific area
21、, then the legislation shall prevail for that specific point only.

22、s part of ISO 16121 specifies minimum requirements for the cabin environment. It applies to the drivers workplace 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 metr
23、ic tonnes and an overall width exceeding 2,30 m. 2 Normative references The following referenced documents are indispensable 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 an

30、ate-control system shall together provide a climate inside the cab that is acceptable to the vast majority of drivers working in the normal conditions prevailing in the region throughout the year. The basic system shall consist of conventional air heating and ventilation, with the option of addition
31、al heating or air conditioning as necessary for the particular operating environment. The climate and ventilation in the drivers cab shall be controllable independently of that of the passenger compartment. 4.2 Climate of drivers cab 4.2.1 Heating The level that is considered as a comfortable interi
32、or temperature and the time it takes to get to that temperature largely depend on the outside temperature and living conditions of the region the vehicle is operated in. The interior climate conditioning is therefore subject to agreement between the client and manufacturer. Annex A provides a recomm
33、endation of heating performance. BS ISO 16121-4:2011ISO 16121-4:2011(E) ISO 2011 All rights reserved 34.2.2 Air conditioning (if fitted) Consideration should be given to the fitness of air conditioning to maintain a comfortable climate in the drivers cab, subject to agreement between client and manu
34、facturer, taking into account the environmental conditions of operation. If both saloon and cab air conditioning systems are required, and these systems are served by the same compressor and condenser unit, then the zone control would be maintained by independent air outlets. Annex A provides a reco
35、mmendation of climate performance. 4.3 Ventilation 4.3.1 The ventilation fan shall have a minimum of three speed settings. 4.3.2 Additional adjustable air nozzles for direct air jets in the direction of the driver shall be provided. The airflow should be such that the nozzles can be closed if requir
36、ed. 4.4 Windscreen defrosting and demisting 4.4.1 The defrosting and demisting system shall ensure that the driving view (front and sides) is kept clear during operation. The specific measurement and performance requirements shall be in compliance with SAE J381. It should be noted that requirements
37、for demisting of the windscreen can be met by the defrosting system as described in SAE J381. 4.4.2 Attention shall be paid to maintain adequate demisting of the window used to provide lateral visibility according to 4.2 of ISO 16121-2:2005. 4.5 Air quality The drivers workplace shall be capable of
38、being ventilated from either external ambient air or re-circulated cabin air. The specific performance requirements are subject to agreement between client and manufacturer. Annex B gives an overview of typical performance criteria measured according to ISO/TS 11155-1 and ISO/TS 11155-2. 5 Noise ins
39、ide the vehicle 5.1 In order to minimize the exposure of the driver to workplace noise, the following measurements should be taken. 5.1.1 The driving noise, expressed as an Leq(taken over two minutes) at 50 km/h, shall not exceed 70 dB(A) at the drivers ear height (measuring method in accordance wit
40、h ISO 5128). The noise level, when stationary and engine is idle, shall be 15 C should be ensured at all adjacent surfaces (excluding all external windows).
