1 Scope This European Standard specifies a measurement method and conditions to obtain reproducible and comparable sound reduction indices of all kinds of rail bound vehicles’ gangway systems defined in EN 16286‑1. The setup should include all components of the system mounted like this is done between two adjacent car bodies within the train, so that a person will be able to use the gangway system, consisting of e.g:
— the bridge system (footplate);
— side panels;
— flexible components (bellows);
— mounting systems;
— elements to couple parts in case of separable gangway systems.
If separable gangway systems shall be measured, the whole system between two adjacent car bodies should be used. The method is applicable to type testing of gangways. This method is not applicable to:
— interior noise measurements in vehicles;
— structure borne noise measurements.
