DIN EN 16286-2:2024-10

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, for example: - 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. The responsible German standardization committee is Working Committee NA 001-01-07 AA "Geräuschemissionsmessungen an spurgebundenen Fahrzeugen einschließlich Messungen im Fahrgastraum und am Arbeitsplatz" ("Measurement of sound exposition on rail vehicles, including measurements inside the passenger compartment and at the workplace") at DIN Standards Committee Acoustics, Noise Control and Vibration Engineering (NALS).
