This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by November 2015, and conflicting national standards shall be withdrawn at the latest by November 2015. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 14389-2:2004. The main change compared to the previous edition is a new presentation of the requirement in order to be coherent with the new EN 14389-1. In the new version, the manufacturer has to declare in Table 1 the working life of non-acoustic performances in function of exposure classes. This part is concerned with long-term durability. It should be read in conjunction with: EN 1793, Road traffic noise reducing devices – Test method for determining the acoustical performance — Part 1: Intrinsic characteristics of sound absorption — Part 2: Intrinsic characteristics of airborne sound insulation under diffuse sound field conditions — Part 6: Intrinsic characteristics – In situ values of airborne sound insulation under direct sound field conditions CEN/TS 1793-5, Road traffic noise reducing devices – Test method for determining the acoustical performance — Part 5: Intrinsic characteristics - In situ values of sound reflection and airborne sound insulation (CEN/TS) EN 1794, Road traffic noise reducing devices - Non-acoustic performance — Part 1: Mechanical performance and stability requirements — Part 2: General safety and environmental requirements — Part 3: Reaction to fire. Burning behaviour of noise reducing devices based on assessment of their components.

4 Introduction Noise reducing 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 structural elements need to retain acceptable minimum safety factors at the end of their working 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 generally a high ageing resistance in many differing conditions. SIST EN 14389-2:2015

EN 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 should 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 dependent 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 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 referenced 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: Classification of groups of environmental parameters and their severities

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 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 transmission of airborne sound emanating from road traffic SIST EN 14389-2:2015

6 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 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) 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 experienced 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 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).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 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 same exposure
