13、orewordISO (the International Organization 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 tec
14、hnical committee has been established has 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 o
15、f electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document
16、 was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).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 p
17、atent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).Any trade name used in this document is information given for the convenience of users and does no
18、t constitute an endorsement.For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISOs adherence to the WTO principles in the Technical Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
19、The committee responsible for this document is ISO/TC 70, Internal combustion engines.This second edition cancels and replaces the first edition (ISO 15550:2002), of which it constitutes a minor revision.iv ISO 2016 All rights reservedBS ISO 15550:2016ISO 15550:2016(E)IntroductionThis document estab
20、lishes the framework for ISO engine power measurement standards. By applying this framework, the disadvantages of the existence of many similar, but different, ISO standards for the definition and determination of engine power can be avoided.This framework uses the “Core” and “Satellite” approach. T
21、he “Core” standard contains the requirements that are common to all engine applications described in the scope and the “Satellite” standard contains those requirements that are necessary to tailor power measurement and declaration to suit a particular engine application.This document is only applica
22、ble in conjunction with a particular “Satellite” standard in order to completely specify the requirements for the particular engine application. The “Core” standard, therefore, is not a document that can stand alone, but only represents addenda to a particular “Satellite” standard used to create a c
23、omplete standard together with the said “Satellite” standard.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 standards in the course of revision or development will be ensured.Thi
24、s document is the “Core” standard.This document was prepared in order to serve as the “Core” standard for making engine power measurements. It was drafted in close co-operation with technical committees ISO/TC 22 Road vehicles, ISO/TC 23 Machinery for forestry and agriculture, ISO/TC 127 Earth movin
25、g machinery and ISO/TC 188 Small craft. The prerequisite for any future modification of this document will be the formal approval of all the above technical committees. Together with the “Satellite” standard for each engine application, the “Core” standard serves as the basis for engine power declar
26、ation and measurement. Each technical committee is fully responsible for the administration of its own “Satellite” standard(s).Any further requirements are subject to agreement between the manufacturer and customer.

27、engines Determination and method for the measurement of engine power General requirements1 Scope1.1 This document specifies standard reference conditions and methods of declaring the power, fuel consumption, lubricating oil consumption and test methods for internal combustion engines in commercial p
28、roduction using liquid or gaseous fuels. It is applicable to the following:a) reciprocating internal combustion (RIC) engines (spark-ignition or compression-ignition engines) but excluding free piston engines;b) rotary piston engines.These engines can be naturally aspirated or pressure-charged eithe
29、r using a mechanical pressure-charger or turbocharger.1.2 This document is applicable to engines used for the following:a) land, rail-traction and marine use as defined in ISO 3046-1;b) the propulsion of automotive vehicles as defined in ISO 1585 and ISO 2534;c) motorcycles as defined in ISO 4106;d)
30、 the propulsion of agricultural tractors and machinese) the propulsion of earth-moving machinery as defined in ISO 9249;f) the propulsion of recreational craft or other small marine craft up to 24 m hull length as defined in ISO 8665.This document can be applied to engines used to propel road constr
31、uction machines, industrial trucks and for other applications where no suitable International Standard for these engines exists.It also can be applied to tests performed both on a test bed at a manufacturers works as well as on site.2 Normative referencesThe following documents are referred to in th
