12、s (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 organizations,
13、 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 given in the ISO
14、/IEC Directives, Part 3. 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 75 % of the m
15、ember bodies casting a vote. Attention is drawn to the possibility that some of the elements of this International Standard may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 14396 was prepared by Technical Committee ISO/TC 70, I

17、2007 01:37:19 MDTNo reproduction or networking permitted without license from IHS -,-,- ISO 14396:2002(E) ISO 2002 All rights reserved v Introduction This International Standard establishes one “Satellite” standard of the ISO engine power measurement standards, the use of which enables one to avoid
18、the disadvantages due to the existance of many similar, but different, ISO standards for the definition and determination of engine power. It uses the “Core” and “Satellite” approach. The “Core” standard, ISO 15550 contains the requirements that are common to all engine applications whereas this Int
19、ernational Standard contains as a “Satellite” standard those requirements that are necessary to tailor power measurement and declaration to suit the particular engine application as defined in clause 1. This International Standard is intended to be applied only in conjunction with the “Core” standar
20、d ISO 15550 in order to completely specify the requirements for the particular engine application. The “Satellite” standard therefore is not a document that can stand alone but is intended to be accomplished by the requirements laid down in the “Core” standard ISO 15550 to become a complete standard
21、. The structure of both, the “Core” and the “Satellite” standard have been drafted in a very similar way to ensure easy use. The advantage of this approach is that the use of standards for the same or similar engines used in different applications will be rationalized and the harmonization of standa
22、rds in the course of revision or development will be ensured. In comparison with engines for on-road applications, engines for off-road use are made in a much wider range of power outputs and configurations as they are used in a large number of different applications. The objective of ISO 8178 is to
23、 rationalize the gaseous and particulate emission test procedures for off-road engines in order to simplify and make more cost effective the drafting of legislation, the development of engine specifications and engine certification. One of the concepts that has been adopted to achieve this objective
24、 is to calculate the specific emissions (g/kWh) on the basis of the engine power when only the essential dependent auxiliaries are fitted. ISO 8178 has been used in legislation and the authorities have set limit values that vary according to the power of the engine. This International Standard defin
