18、rvedForeword ISO (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
19、 a technical 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 mat
20、ters of electrotechnical standardization. International 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 circu
21、lated to the member bodies for voting. Publication 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 responsi
22、ble for identifying any or all such patent rights. ISO 8528-5 was prepared by Technical Committee ISO/TC 70, Internal combustion engines. This second edition cancels and replaces the first edition (ISO 8528-5:1993), which has been technically revised. ISO 8528 consists of the following parts, under
23、the general title Reciprocating internal combustion engine driven alternating current generating sets: Part 1: Application, ratings and performance Part 2: Engines Part 3: Alternating current generators for generating sets Part 4: Controlgear and switchgear Part 5: Generating sets Part 6: Test metho

26、 ISO 8528-5:2005(E) ISO 2005 All rights reserved 1Reciprocating internal combustion engine driven alternating current generating sets Part 5: Generating sets 1 Scope This part of ISO 8528 defines terms and specifies design and performance criteria arising out of the combination of a Reciprocating In
27、ternal Combustion (RIC) engine and an Alternating Current (a.c.) generator when operating as a unit. It applies to a.c. generating sets driven by RIC engines for land and marine use, excluding generating sets used on aircraft or to propel land vehicles and locomotives. For some specific applications
28、 (e.g. essential hospital supplies and high-rise buildings) supplementary requirements may be necessary. The provisions of this part of ISO 8528 should be regarded as a basis for establishing any supplementary requirements. For generating sets driven by other reciprocating-type prime movers (e.g. st
29、eam engines), the provisions of this part of ISO 8528 should be used as a basis for establishing these requirements. 2 Normative references The following referenced documents are indispensable for the application of this document.

34、erm “rated” and the subscript “N”. For indications of technical data for mechanical equipment, ISO uses the term “declared” and the subscript “r”. Therefore, in this part of ISO 8528, the term “rated” is applied only to electrical items. Otherwise, the term “declared” is used throughout. An explanat
