12、geBS ISO 8528-8:2016ISO 8528-8:2016(E) Foreword 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 bod
13、y interested in a subject for which 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 Electrote
14、chnical Commission (IEC) on all matters of 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 IS
15、O documents should be noted. This document 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 re
16、sponsible for identifying any or all such patent 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).

22、requirements, minimum performances and type tests for low- power generating sets driven by reciprocating internal combustion engines for land and marine use (domestic, recreational and industrial application), excluding generating sets used on aircraft. It concerns mainly low-power generating sets d
23、riven by reciprocating internal combustion engines for the generation of single or multiphase alternating current or direct current up to 500 V. The generating sets are standard manufactured sets. In this part of ISO 8528, “low-power” is taken to mean rated power of a magnitude up to approximately 1
24、0 kW/50 Hz, 12 kW/60 Hz. Low-power generating sets, for the purpose of this International Standard, are determined by the following special features: the users normally are laymen (for further details, see 3.1); the complete generating set is usually transportable or mobile; the electrical output is
25、 connected by means of plugs, sockets and screwed terminal except for extra low voltages; the generating set is ready for use without any additional installation work by the user. Generating sets for special applications or of higher rated power conforming to the above special features may, by agree
26、ment between manufacturer and customer, be tested in accordance with this part of ISO 8528. If supplementary stipulations are required for certain applications, this is to be done taking this part of ISO 8528 as a basis. This part of ISO 8528 deals with the special requirements of design and test wh
27、ich are observed in addition to the definitions and requirements laid down in ISO 8528-1, ISO 8528-2, ISO 8528-3, ISO 8528-4, ISO 8528-5 and ISO 8528-6, where applicable. This part of ISO 8528 does not deal with safety requirements in order to protect the user from dangers which are laid down in ISO
28、 8528-13. NOTE This International Standard does not apply to arc welding equipment (IEC 60974 series). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
