ISO 3095:2013 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".
ISO 3095:2013 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.).
