DIN EN 16286-2:2013-09 EN 16286-2:2013 (E) 4 Introduction This European Standard presents a measurement method to collect information about the noise insulation of rail bound vehicle gangway systems. These components need their own measurement procedure as the geometrical sou
28、nd distribution situation is not in line with the basic assumptions of general standards about noise insulation measurements as provided for building elements, etc. In this standard, a number of different setups are described, which represent possible approaches to the ideal test situation. As the a
29、pproaches may contradict the ideal sound fields, the standard includes methods to assess the influence of reflections and other difficulties in order to reduce the uncertainties of these test methods to an acceptable amount in Annex A. DIN EN 16286-2:2013-09 EN 16286-2:2013 (E) 5 1 Scope This Europe
30、an 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
31、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 measu
32、red, 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. The type testing procedures specified in this European Standard a
33、re of engineering grade (grade 2) in the frequency range from 100 Hz up to 5 kHz; that is the preferred range for noise declaration purposes, as defined in EN ISO 12001. If test conditions are relaxed, the results are no longer of engineering grade. 2 Normative references The following documents, in
