5、ord This document (EN 14389-2:2015) has been prepared by Technical Committee CEN/TC 226 “Road equipment” (Secretariat: AFNOR, France).

6、tee NA 005-10-26 AA Lrmschutz-vorrichtungen (SpA zu CEN/TC 226/WG 6), Gemeinschaftsausschuss mit FGSV. At the beginning of 2013 the responsible German Working Committee decided to make a change to the German titles of the DIN EN 1793 series of standards. It was decided to change the German term Lrms
7、chutzeinrichtung to Lrmschutzvorrichtung (noise reducing device) in all of the titles. The German titles in the series have thus been modified. Some inconsistencies will remain as regards these titles (e.g. in the Normative References or Bibliographies) until all of the standards in the DIN EN 1793
8、series and other related standards are revised. Amendments This standard differs from DIN EN 14389-2:2004-11 as follows: a) a new presentation of the requirements has been introduced to be in line with the new EN 14389-1; b) in Table 1, the manufacturer has to declare the working life of the acousti

DIN EN 14389-2:2015-07 (E) EN 14389-2:2015 (E) 4 Introduction Noise reducing devices alongside
27、 roads should not only fulfil their acoustic function and structural design requirements in accordance with appropriate documents, but also maintain their performance during the required working life. The structural elements need to retain acceptable minimum safety factors at the end of their workin
28、g life and the acoustic elements not only have to remain effective structurally but provide the specified acoustic performance. All elements in the construction of noise reducing devices should be resistant to electrolytic or/and chemical corrosion and embrittlement, be dimensionally stable and have
29、 generally a high ageing resistance in many differing conditions. DINEN 14389-2:2015-07EN 14389-2:2015 5 1 Scope This European Standard specifies requirements for assessing the working life and provides the relevant exposure conditions. Standards of construction and any material tests conducted shou
30、ld provide evidence of resistance to specified conditions selected from the following: I. Chemical Agents Location 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 depen
31、dent VII. Heat Climate dependent VIII. UV Radiation Climate dependent IX. Traffic Vibration Location dependent X. Biological Process Climate dependent XI. Ozone Location dependent XII. Water Climate dependent XIII. Water spray (Wet/dry) Location dependent NOTE Special care is taken for combinations
32、of different materials, whether inside a single device or in combination with other devices (for example: 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 ref
33、erenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 60721-3-4, Classification of environmental conditions Part 3: Classif

35、 to reduce the propagation of traffic noise away from the road environment Note 1 to entry: This may be a noise barrier, cladding, a road cover or an added device. These devices may include both acoustic and structural elements. 3.2 noise barrier noise reducing device, which obstructs the direct tra

37、c elements 3.5 cladding noise reducing device, which is attached to a wall or other structure and reduces the amount of sound reflected 3.6 cover noise-reducing device, which either spans or overhangs the highway 3.7 added device added component that influences the acoustic performance of the origin
38、al noise-reducing device (acting primarily on the diffracted energy) 3.8 working life period of time during which the performance of the device will be sustained which enables it to fulfil the performance characteristics as identified in EN 1794 parts 1, 2 and 3 3.9 roadside exposure conditions expe
39、rienced by the noise reducing devices installed alongside a road 4 Requirements The structural design shall comply with the requirements of the appropriate European code. Standard environmental categories selected for road traffic noise reducing devices with possible variations are given in Annex A
40、of this document. The manufacturer shall list the measures taken to limit the effects of ageing on his product following the list of ageing agents I to XIII and the adverse effects of combining different materials. Where material standards exist, durability shall be assessed using them (see Annex B)
41、.The manufacturer shall define the working life under the exposure classes, listed in the Table 1,adapted to the intended use of the noise reducing device. In any cases, the working life of the noise reducing device is the minimum of the working lives of its components. Adverse effects on long-term
42、performance of contact with the ground shall be taken into account. If retention of water is likely to degrade the working life, the design shall ensure that water is not retained. The working life of structural and acoustic elements may be different, therefore they have to be assessed under the sam
43、e exposure conditions when installed on the same site. If a change in humidity and/or temperature and/or UV affects the dimensional stability of materials used in the construction, then the design shall allow for such changes and ensure that the performance continues to fulfil the performance charac
44、teristics. DIN EN 14389-2:2015-07 EN 14389-2:2015 7 Where different materials are used in the construction, all appropriate measures shall be taken to avoid electrolytic and chemical corrosion or interaction that could adversely affect working life.
