Railway applications - Gangway systems between vehicles - Part 2: Acoustic measurements

Scope

This document specifies a measurement method and conditions to obtain reproducible and comparable sound reduction indices of all kinds of rail bound vehicles’ gangway systems as specified in EN 16286 1. The setup includes 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 the case of separable gangway systems.
The method is applicable to type testing of gangways.
This method is not applicable to:
— interior noise measurements in vehicles;
— structure borne noise measurements.
The type testing procedures specified in this document are of engineering grade (grade 2) in the frequency range from 100 Hz up to 5 000 Hz.
NOTE This is the preferred range for noise declaration purposes, as specified in EN ISO 12001. If test conditions are relaxed, the results are no longer of engineering grade (grade 2).
