scope:

This part of IS0 8528 defines 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 driven 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 that can be selected from a commercial catalogue or leaflet

In this part of IS0 8528, "low power" is taken to mean power of a magnitude up to approximately 10 kW

NOTE 1 An exact determination of a power limit is not possible

Low-power generating sets for the purpose of this standard are determined by the following special features

- the users normally are laymen (for further details see 3 I);

- the complete generating set is usually transportable, or mobile;

- the electrical output is connected by plugs and sockets (except for extra low voltages, see 6 6 3),

- 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 agreement between manufacturer and customer, be tested in accordance with this part of ISO 8528 If supplementary stipulations are required for certain applications this should be done taking this part of ISO 8528 as a basis

This part of ISO 8528 deals with the special requirements of test and safety design which should be observed in addition to the definitions and requirements laid down in ISO 8528 parts 1 to 6, where applicable

Furthermore it lays down safety requirements in order to protect the user from danger
