11、ion” published by the International Organization for Standardization (ISO). ISO6011 was produced as a result of international discussions in which the United Kingdom took an active part. Terminology and conventions. The text of the International Standard has been approved as suitable for publication
12、 without deviation, as a British Standard. Some terminology and certain conventions are not identical with those used in British Standards; attention is especially drawn to the following. Wherever the words “International Standard” appear, referring to this standard, they should be read as “British
13、Standard”. NOTETextual error. In the note to Figure 5 “Km/h” should be read as “km/h”. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of i

This standard has been updated (see copyright date) and may have had amendments incorporated. This will be indicated in the amend
15、ment table on the inside front cover.BS5768:1979 BSI 12-1999 1 1 Scope This International Standard specifies the information an operator shall be able to obtain from the instrumentation at the instrument panel and the arrangement of this instrumentation in order to make it possible to operate the ma
16、chine in a safe and proper way and to maintain it in good operating condition. For guidance, an annex sets forth specified space envelope, preferred dimensions and dial-face layout of some instruments which are frequently used today. 2 Field of application This International Standard applies to the
17、following types of operator-controlled machine: crawler loaders and dozers; wheel loaders and dozers; graders; tractor scrapers; self-propelled compactors; excavators; off-highway trucks. 3 Instrumentation Instrumentation at the instrument panel shall provide information according to Table 1. In the

23、d into groups on the panel as shown in Figure 1. Left group: for engines (for example engine water thermometer, oil pressure gauge, etc.) Central group: for driving machines (for example speedometer, engine tachometer, etc.) Right group: for power transmission (for example torque converter oil therm

25、trument panel of earth-moving machinery. The specifications are only given for guidance. Manufacturers are free to use any instrument (for example control light, warning lamp) which gives the desired information in a useful way.
