11、rdization) 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 has been established has the right t
12、o 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 electrotechnical standardization. International Sta
13、ndards 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 bodies for voting. Publication as an In
14、ternational 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 or all such patent rights.

BS ISO 10975:2009ISO 10975:2009(E) iv ISO 2009 All rights reservedIntroduction Auto-guidance systems are used in tractors and self-propelled agricultural machi
16、nes to reduce operator fatigue and to increase the accuracy and efficiency of field operations. To ensure the proper function and safety of such systems, this International Standard specifies requirements for controls and displays, activation and deactivation of the system, audible and/or visual ind
17、icators to show the status of the system and the information to be provided to the operator. According to the current practice, these requirements are applicable to factory installed systems and systems intended to be retrofitted.

18、l rights reserved 1Tractors and machinery for agriculture Auto-guidance systems for operator-controlled tractors and self-propelled machines Safety requirements 1 Scope This International Standard specifies safety requirements for auto-guidance systems used in agricultural tractors and self-propelle
19、d agricultural machines. It is applicable to auto-guidance systems which are factory installed as an integral part of the tractor or self-propelled machine as well as systems designed to be retrofitted to equipment after such equipment has left the control of the manufacturer. It is not applicable t
20、o guidance systems used in tractors or self-propelled machines that do not require an on-board operator for primary control of the tractor or self-propelled machine. This International Standard does not specify requirements necessary to ensure the integrity of the complex electronic control system w
21、hich can be an integral part of the auto-guidance system. Such requirements are dealt with in other International Standards which address complex electrical/electronic vehicle control systems. When requirements of this International Standard are different from those which are stated in a machine spe
22、cific standard, the requirements of the machine specific standard take precedence over the requirements of this International Standard. This International Standard is neither applicable to tractors and self-propelled machines which were manufactured with an auto-guidance system before the date of pu
23、blication of this International Standard, nor to self-contained auto-guidance retrofit systems which were individually placed on the market before the date of publication of this International Standard. NOTE Specific road traffic regulations can impose additional requirements for auto-guidance syste
