NATIONAL FOREWORD

This Indian Standard (Part 10) (First Revision) which is identical to ISO 8528-10 : 2022 'Reciprocating internal combustion engine driven alternating current generating sets — Part 10: Measurement of airborne noise' issued by International Organization for Standardization (ISO), was adoptedby 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 IS/ISO 8528-10 : 1998. This revision of the standard has been brought out to align it with ISO 8528-10 : 2022.

The major changes incorporated in this revision are as follows:

a) The normative references have been updated;

b) The latest requirements of ISO 3744 : 2010 and ISO 3746 : 2010 have been included, respecting ISO 12001 : 1996 requirements;

c) The measurement surfaces have been updated;

d) The definition of the reference box in special cases has been added;

e) The guaranteed sound power level has been added;

f) Requirements concerning variable speed engine gensets, fans and lighting towers have been added;

g) The requirements for welding generators have been updated; and

h) The determination of the emission sound pressure level at workstation has been updated.

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 12 Emergency power supply to safety services

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 currentpractice is to use a point (.) as the decimal marker.
