ISO 10815:2016 establishes the basic principles for measuring, processing and evaluating vibration generated internally in railway tunnels by the passage of trains.
By establishing a standard procedure, comparative data may be obtained on response of the tunnel elements from time to time, provided that the excitation source is the same. Data obtained in different tunnels may also be compared.
The measurements considered in ISO 10815:2016 concern the response of the structure and secondary elements mounted in the tunnel. They do not concern the response of persons in the tunnel or in its vicinity, or of passengers on trains running through the tunnel.
