12、n 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 has been established has
13、 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 electrotechnical standardization. Inter
14、national 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 bodies for voting. Publicat
15、ion 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 or all such patent righ

Computer-based system
18、s, generically referred to as programmable electronic systems (PES), are at present being used in all application sectors to perform non- safety-related and, increasingly, safety-related functions. If computer system technology is to be effectively and safely exploited, it is essential that those re
19、sponsible for making decisions have sufficient guidance on the safety aspects on which to base these decisions. This International Standard addresses systems comprising electrical and/or electronic and/or programmable electronic components electrical/electronic/programmable electronic systems (E/E/P
20、ES) used for functional safety in earth-moving machinery. In most situations, safety is achieved by a number of protective systems which rely on many technologies (e.g. mechanical, hydraulic, pneumatic, electrical, electronic, programmable electronic). Any safety strategy must therefore consider not
21、 only all the elements within an individual system, such as sensors, controlling devices and actuators, but also all the safety-related systems. Therefore, while this International Standard is concerned with safety-related E/E/PES, it could also provide guidance for safety-related systems based on o
22、ther technologies. This International Standard has been conceived with a rapidly developing technology in mind, with a framework sufficiently robust and comprehensive to meet the demands of that technology, provides a method for the development of safety requirement specifications necessary to defin
23、e the required functional safety for E/E/PES, and presents a methodology for specifying the target level of safety integrity for the safety functions to be implemented by the E/E/PES, using a risk-based approach.
