1 Scope 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;
