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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document was prepared by Technical Committee ISO/TC 43, Acoustics, Subcommittee SC 1, Noise.
This fourth edition cancels and replaces the third edition (ISO 3095:2013), which has been technically
revised.
The main changes compared to the previous edition are as follows:
— the alignment of measurement conditions with ISO 3381:2021
— an improvement of the tonality assessment
— the introduction of specific measurement conditions for hybrid vehicles
— a new informative Annex C providing guidance information on the track influence on pass-by test
results
— an improved specification for additional noise measurements on bridges and other elevated
structures in concrete bridge sections (see Annex E)
— a new informative Annex G specifying the measurement method for parking noise
Any feedback or questions on this document should be directed to the user’s national standards body. A

Introduction
Railway exterior noise is encountered both along open track and in and around depots, stops, stations
and other holding locations. It includes a number of different physical sources such as rolling noise,
impact noise, traction noise, aerodynamic noise, curving noise, braking noise, horn noise and noise
from auxiliary equipment and other components. The noise for any given train type strongly depends
on the rolling stock design, operating conditions and the track type and condition.
Rolling noise is one of the main sources which contain a significant and sometimes dominant noise
contribution from the track. This International Standard is intended to characterize the noise emission
from the unit, minimizing the influence of the track.
