BS EN 16951-1:2018EN 16951-1:2018 (E) 5 Introduction Noise barriers and related devices acting on sound propagation alongside railways should not only fulfil their acoustic function and structural design requirements in accord
37、ance with appropriate documents, but also maintain their performance during the required working life. The acoustic elements need to resist the actions of agents within the line side environment that could significantly degrade their performance. The acoustic characteristics of noise barriers and re
38、lated devices acting on sound propagation can deteriorate significantly over the duration of their working life if they are not installed or maintained in accordance with the manufacturers recommendations, or if the materials are not appropriate for the line side environment. All elements in the con
39、struction of noise barriers and related devices acting on sound propagation should be resistant to electrolytic or/and chemical corrosion and embrittlement, be dimensionally stable and have generally a high ageing resistance in many differing conditions. BS EN 16951-1:2018EN 16951-1:2018 (E) 6 1 Sco
40、pe This European Standard specifies requirements for assessing the working life and provides the relevant exposure conditions. Standards of construction and any material tests conducted should provide evidence of resistance to specified conditions selected from the following: I. Chemical Agents Loca
41、tion dependent II. De-icing salt Location/climate dependent III. Dirty water/dust Location/climate dependent IV. Dew Climate dependent V. Freeze/thaw Climate dependent VI. Cold Climate dependent VII. Heat Climate dependent VIII. UV Radiation Climate dependent IX. Traffic Vibration Location dependent
42、 X. Biological Process Climate dependent XI. Ozone Location dependent XII. Water Climate dependent XIII. Water spray (Wet/dry) Location dependent NOTE Combinations of different materials are worth a special attention, whether inside a single device or in combination with other devices (for example:
43、a combination of different acoustic elements or another combination of acoustic and structural elements). 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition
44、 cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

47、ound reflected Note 1 to entry: Claddings are generally made of acoustic and structural elements (see 3.3 and 3.4). 3.3 acoustic element element whose primary function is to provide the acoustic performance of the device 3.4 structural element element whose primary function is to support or hold in
48、place acoustic elements Note 1 to entry: In some noise barriers, the acoustic function and the structural function cannot be clearly separated and attributed to different components. 3.5 added device added component that influences the acoustic performance of the original noise-reducing device (acti
