10、) 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 to be repr
11、esented 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 Standards ar

Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an Internation
13、al 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.

17、6 specifies the common measurement techniques of the main performance parameters of reciprocating internal combustion engines, in addition to the basic requirements defined in ISO 15550. This is to ensure that the required accuracy of measurement is achieved for comparison of the measured values wit
18、h those values specified by the engine manufacturer. Where necessary, individual requirements may be given for particular engine applications. This part of ISO 3046 applies to reciprocating internal combustion engines for land, rail-traction and marine use. It may be applied to engines used to prope
19、l road construction machines, industrial trucks, and for other applications where no suitable International Standards for these engines exist. 2 Normative references The following referenced documents are indispensable for the application of this document.
