21/30437521 DC

This standard 21/30437521 DC BS ISO 10326-2. Mechanical vibration. Laboratory method for evaluating vehicle seat vibration is classified in these ICS categories:

• 45.060.01 Railway rolling stock in general
• 13.160 Vibration and shock with respect to human beings

This part of ISO 10326 defines specifications covering laboratory tests for seats designed for passengers and crew in railway tractive and trailer vehicles.

It concerns tri-axial rectilinear vibration within the frequency range 0,5 Hz to 50 Hz. It specifies the inputs test vibration to be used at seat testing.

This part of ISO 10326 makes it possible to characterize, in the form of frequency response functions, the manner in which vibration is transmitted to the seat occupant. It also provides an estimator showing the behaviour of the seat in terms of dynamic comfort perceived by the seated person.

Different type of excitations can be used and are described depending on knowledge of the vibration environment encountered by the seat and the capability of the vibration simulator.
