NATIONAL FOREWORD

This Indian Standard (Part 12) (First Revision) which is identical to ISO 8528-12 : 2022 'Reciprocating internal combustion engine driven alternating current generating sets — Part 12: Emergency power supply to safety services' issued by International Organization for Standardization (ISO) was adopted by the Bureau of Indian Standards on the recommendations of Automotive Prime Movers, Transmissions Systems and Internal Combustion Engines Sectional Committee and approval of the Transport Engineering Division Council.

This standard was first published in 2012 which was identical with ISO 8528-12 : 1997. This revision has been brought out to align it with ISO 8528-12 : 2022. The major changes incorporated in this revision are as follows:

a) Structure updated according to the current ISO template;

b) Normative references updated;

c) Previous 4 deleted – the symbols used in ISO 8528-5 now apply;

d) Clause 7 split into subclauses;

e) Hanging paragraphs removed from 8 and 9;

f) Values in Table 3 modified based on the values in ISO 8528-5 : 2022, Table 4; and

g) Minor editorial changes.

This standard is one of the series of standards published on reciprocating internal combustion engine driven alternating current generating sets. Other standards in this series are:

Part 1 Applications, ratings and performance

Part 2 Engines

Part 3 Alternating current generators for generating sets

Part 4 Control gear and switch gear

Part 5 Generating sets

Part 6 Test methods

Part 7 Technical declaration 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

The text of the ISO standard has been approved as suitable for publication as an Indian Standard without deviations. Certain terminologies and conventions are, however, not identical to those used in Indian Standards. Attention is particularly drawn to the following:

a) Wherever the words 'International Standard' appear referring to this standard, they should be read as 'Indian Standard'; and

b) Comma (,) has been used as a decimal marker, while in Indian Standards, the current practice is to use a point (.) as the decimal marker.
