5、ument (EN 14389-1:2015) has been prepared by Technical Committee CEN/TC 226 “Road equipment” (Secretariat: AFNOR, France). The responsible German body involved in its preparation was the DIN-Normenausschuss Bauwesen (DIN Standards Committee Building and Civil Engineering), Working Committee NA 005-1

6、0-26 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 Lrmschutzeinrich

7、tung 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 series and o

8、ther related standards are revised. Amendments This standard differs from DIN EN 14389-1:2008-02 as follows: a) a new presentation of the requirements has been introduced to be in line with the new EN 14389-2; b) in Table 1, the manufacturer has to declare the working life of the acoustic performanc

DIN EN 14389-1:2015-07 EN 14389-1:2015 (E) 5 Introduction Noise Reducing

27、 Devices alongside 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 acoustic elements have to resist the actions of agents within the roadside en

28、vironment that could significantly degrade their performance. The acoustic characteristics of a Road Traffic Noise Reducing Device can deteriorate significantly over the duration of its working life if it is not installed or maintained in accordance with the manufacturers recommendations, or if the

29、materials are not appropriate for the roadside environment. 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 generally a high ageing resistance in many differing conditions. DI

30、NEN 14389-1:2015-07EN 14389-1:2015(E)6 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 should provide evidence of resistance to specified conditions selected

31、 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 dependent VII. Heat Climate dependent VIII. UV Radiation Climate depend

32、ent 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 of different materials, whether inside a single device or in combi

33、nation 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 referenced in this document and are indispensable for its application.

34、 For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

35、Section 4: Stationary use at non -weatherprotected locations (IEC 60721-3-4) 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 noise reducing device (NRD) device that is designed to reduce the propagation of traffic noise away from the road env

36、ironment 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. DIN EN 14389-1:2015-07 EN 14389-1:2015 (E) 7 3.2 noise barrier noise reducing device, which obstructs the direct transmission of airborne

37、 sound emanating from road traffic 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 place acoustic elements 3.5 cladding noise reducing device, which is attached to

38、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 original noise-reducing device (acting primarily on the diffracted energy)

39、 3.8 working life period of time during which the declared acoustic performance(s) DL(from EN 1793-1) and/or DLR(from EN 1793-2) and/or DLSI(from EN 1793-6) of the device will be maintained 3.9 roadside exposure conditions experienced by the noise reducing device installed alongside a road 4 Require

40、ments Standard environmental categories selected for road traffic noise reducing devices with possible variations are given in Annex A of this document. The manufacturer shall provide the relevant acoustic performance characteristic (DLand/or DLRand/or DLSI) at the end of the working lifetime of the

41、 product and define the corresponding working life under the exposure classes, listed in the Table 1, adapted to the intended use of the noise reducing device. Where material standards exist, durability shall be assessed using them (see Annex B). Adverse effects on long-term performance of contact w

42、ith 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 same exposure conditions wh

43、en 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 characteristics. DINEN 14389-1

44、:2015-07EN 14389-1:2015 (E) 8 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. NOTE This European Standard permits specifying authorities to indicate w
