Scope
This standard specifies the measurement conditions for the internal noise level and frequency spectrum of railway vehicles or other various track vehicles, in order to obtain reproducible and comparable measurement results. However, it does not include track maintenance vehicles in operation.
This standard applies to:
——type testing;
——periodic supervision inspections;
——routine noise testing.
