ISO 8528-5:2013(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 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.

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 circulated 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 responsible for identifying any or all such patent rights.

ISO 8528-5 was prepared by Technical Committee ISO/TC 70, Internal combustion engines.

This third edition cancels and replaces the second edition (ISO 8528-5:2005), which has been technically revised.

ISO 8528 consists of the following parts, under 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 methods

— Part 7: Technical declarations for specification and design

— Part 8: Requirements and tests for low-power generating sets

— Part 9: Measurement and evaluation of mechanical vibrations

— Part 10: Measurement of airborne noise by the enveloping surface method

— Part 111): Rotary uninterruptible power systems — Performance requirements and test methods

— Part 12: Emergency power supplies to safety services

1) Part 11 is published as IEC 88528-11:2004.
