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 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 procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part In particular the different approval criteria needed for the different types of ISO documents should be noted This

alternating current generating sets — Part : Safety Scope This part of ISO 8528 speci fies the safety requirements for reciprocating internal combustion (RIC) engine driven generating sets up to 00 V consisting of an RIC engine, an alternating current (AC ) generator including the additional equipment required for operating, e.g controlgear, switchgear, auxiliary equipment It is applicable to generating sets for land and marine use (domestic, recreational and industrial application) It is not applicable to generating sets used on board of seagoing vessels and mobile offshore units as well as on aircraft or to propel road vehicles and locomotives NOTE This part of ISO 8528 does not apply to arc welding equipment (IEC 60974 series) The special requirements needed to cover operation in potentially explosive atmospheres are not covered in this part of ISO 852 The hazards relevant to RIC engine driven generating sets are identi fied in Annex A This part of ISO 8528 deals with the special requirements of test and safety design which should be observed in addition to the de finitions and requirements in ISO 8528-1, ISO 8528-2, ISO 8528-3, ISO 8528-4, ISO 8528-5 and ISO 8528-6, where applicable It speci fies safety requirements in order to protect the user from danger Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application For dated references, only the edition cited applies For undated references, the latest edition of the referenced document (including any amendments)
