12、on 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 technical committee has been established ha
13、s 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 of electrotechnical standardization.The p
14、rocedures 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 was drafted in accordance with the edit
15、orial 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.

21、D ISO 8528-8:2016(E)Reciprocating internal combustion engine driven alternating current generating sets Part 8: Requirements and tests for low-power generating sets1 ScopeThis part of ISO 8528 defines design requirements, minimum performances and type tests for low-power generating sets driven by re
22、ciprocating 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 driven by reciprocating internal combustion engines for the generation of single or multiphase
23、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 10 kW/50 Hz, 12 kW/60 Hz. Low-power generating sets, for the purpose of this International Stand
24、ard, 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 connected by means of plugs, sockets and screwed terminal except for extra low voltages; the g
25、enerating 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 agreement between manufacturer and customer, be tested in accordance with this part of ISO 8528. If s
26、upplementary 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 which are observed in addition to the definitions and requirements laid down in ISO 8528-1, ISO 852
27、8-2, 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 8528-13.NOTE This International Standard does not apply to arc welding equipment (IEC 60974 serie
