European foreword
This document (prEN 14389:2021) has been prepared by Technical Committee CEN/TC 226 “Road
equipment”, the secretariat of which is held by AFNOR.This document is currently submitted to the CEN Enquiry.
This document will supersede EN 14389-1:2015 and EN 14389-2:2015.
The main change compared to the previous edition is the inclusion of the method for assessing long
term performance regarding “non acoustic” characteristics.This document should be read in conjunction with:
— EN 1793, Road traffic noise reducing devices – Test method for determining the acoustical
performance:— Part 1: Intrinsic characteristics - Sound absorption under diffuse sound field;
— Part 2: Intrinsic characteristics – Airborne sound insulation under diffuse sound field;
— Part 5: Intrinsic characteristics – Sound absorption under direct sound field;— Part 6: Intrinsic characteristics – Airborne sound insulation under direct sound field;
— EN 1794, Road traffic noise reducing devices - Non-acoustic performance:— Part 1: Methods of determination of the mechanical performance and stability characteristics;
— Part 2: Methods of determination of the general safety and environmental characteristics;

Introduction
Road Traffic Noise Reducing Devices alongside roads will maintain their characteristics during the
declared working life.Resistance to electrolytic or/and chemical corrosion and embrittlement, dimensional stability and
ageing resistance are considered by the manufacturer for different environmental conditions.
A change of acoustic characteristics can be foreseen depending on the material used and the
environmental exposure conditions. Significant deterioration of the acoustic characteristics is avoided
when appropriate materials for the roadside environment are used and manufacturer’s
recommendations for installation and maintenance are respected.---------------------- Page: 6 ----------------------

3 Terms and definitions
For the purposes of this document, the following terms and definitions apply.
ISO and IEC maintain terminological databases for use in standardization at the following addresses:

3.1
road traffic noise reducing device
RTNRD
device that is designed to reduce the propagation of traffic noise away from the road environment
Note 1 to entry: The RTNRD may comprise acoustic elements (3.2) only or both structural (3.3) and acoustic
elements.Note 2 to entry: Applications of RTNRD include noise barriers (3.4), claddings (3.5), covers (3.6) and added
devices (3.7).3.2
acoustic element
element whose primary function is to provide the acoustic characteristic of the device
3.3structural element
element whose primary function is to support or hold in place acoustic elements
3.4
noise barrier
noise reducing device, which obstructs the direct transmission of airborne sound emanating from road
traffic3.5
cladding
noise reducing device, which is attached to a wall or other structure and reduces the amount of sound
reflected3.6
cover

3.7
added device
added component that influences the acoustic characteristic of the original noise-reducing device
Note 1 to entry: The added device is acting primarily on the diffracted energy.3.8
working life
period of time during which the declared performance(s) of the product will be maintained
3.9roadside exposure
conditions experienced by the noise reducing device installed alongside a road
4 Determination of the characteristics
The determination of the working life of RTNRDs shall be based on the behaviour of the materials
RTNRDs are made of with reference to different environmental categories with possible variations as
given in Annex A of this document.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).Adverse effects on long-term performance of contact with the ground shall be considered.
As water retention is likely to degrade the working life, evaluation shall be made of the extent to which
the RTNRD is retaining water.---------------------- Page: 8 ----------------------
oSIST prEN 14389:2022
prEN 14389:2021 (E)
If a change in humidity and/or temperature and/or UV affects the dimensional stability of materials
used in the construction, then evaluation shall be made how RTNRD shall allow for such changes and
ensure characteristics remain fulfilled along the whole working life.Where different materials are used in the construction, evaluation shall be made of the appropriate
measures taken to avoid electrolytic and chemical corrosion or interaction that could adversely affect
working life.The working life of structural and acoustic elements may be different; therefore, it shall be assessed
under the same exposure conditions.Evaluation shall be made of the relevant acoustic characteristics (DL and/or DL and/or DL
α,NRD RI SI,Eand/or DL ) at the end of the working lifetime of the RTNRD.
SI,P
The evaluation for the characteristic DL shall be omitted, as the measurement method according to the
corresponding technical standard cannot be applied to check the performance of the product at the end
of the working life.The corresponding working life in years shall be defined under the exposure classes, listed in Table 1,
together with the value expressed in decibel of the acoustic performances at the end of the working life.
Where material standards exist, long term performance shall be assessed using them (see Annex B).
The evaluation may be omitted for any exposure classes not covered by the intended use of the RTNRD.
