Description / Abstract:
This International Standard specifies measurement methods and
conditions to obtain reproducible and comparable exterior noise
emission levels and spectra for all kinds of vehicles operating on
rails or other types of fixed track, hereinafter conventionally
called "unit".
This International Standard is applicable to type testing of
units. It does not include all the instructions to characterize the
noise emission of the other infrastructure related sources
(bridges, crossings, switching, impact noise, curving noise,
etc.).
This International Standard is not applicable to:
— the noise emission of track maintenance units while
working;
— environmental impact assessment;
— noise immission assessment;
— guided buses;
— warning signal noise.
The results may be used, for example:
— to characterize the exterior noise emitted by units;
— to compare the noise emission of various units on a particular
track section;
— to collect basic source data for units.
NOTE 1 The type testing procedures specified in this
International Standard are of engineering grade (grade 2), that is
the preferred one for noise declaration purposes, as defined in ISO
12001. If test conditions (e.g. vehicle and/or track conditions,
measuring conditions) are relaxed (e.g. as done for trackside
monitoring of in-service trains), then the results are no longer of
engineering grade.
NOTE 2 The procedures specified for accelerating and
decelerating tests are of survey grade, see ISO 12001.
NOTE 3 Additional guidance is provided in Annex D for
measurements in the specific case of light rail vehicles.
