This document specifies a method for evaluating the working life of noise reducing devices used alongside roads according to the relevant exposure conditions.
It also specifies a method for determining the acoustic characteristic at the end of the working life.

This document outlines a method to measure the typical external noise emission produced when tyres of passenger car roll over a structured road marking. The result is a measure for the noise perceived in the surroundings of the road, hence not for interior noise in the car.
This method can be used for three purposes:
- determination of initial acoustic properties of a road marking, yielding a noise label for a given system;
- testing of the acoustic conformity of a particular marking to the noise label determined during the determination of initial acoustic properties;
- monitoring of the acoustic properties in the course of its lifetime.
The test result allows the road owner to make an assessment of the risk of nuisance when s/he considers a particular road marking system for application on a road in a noise sensitive area, e.g. built up areas. The method is also applicable to measurements on milled rumble strips.

This document provides the current road equipment suppliers’ visions and their associated short term and medium-term priority deployment scenarios. Potential functional/operational standardization issues enabling a safe interaction of road equipment/infrastructure with automated vehicles in a consistent and interoperable way are identified. This is paving the way for a deeper analysis of standardization actions which are necessary for the deployment of priority short-time applications and use cases.
This deeper analysis will be done at the level of each priority application/use case by identifying existing standards to be used, standards gaps/overlaps and new standards to be developed to support this deployment.
The release 1 is focusing on short-term (2022 to 2027) and medium-term deployment. Further releases will update this initial vision according to short term deployment reality.
The objectives of this document are to:
-   Support the TC 226 and its WG12 work through the development of a common vision of the roles and responsibilities of a modern, smart road infrastructure in the context of the automated vehicle deployment from SAE level 1 to SAE level 5. The roles and responsibilities of the road infrastructure are related to its level of intelligence provided by functions and data being managed at its level.
-   Promote the road equipment suppliers and partners visions associated to their short-term and medium- term priorities to European SDOs and European Union with the goal of having available relevant, consistent standards sets enabling the identified priority deployment scenarios.
NOTE   Road equipment/infrastructure includes the physical reality as its digital representation (digital twin). Both need to present a real time consistency.

-   a structural element is an element whose primary function is to support or hold in place acoustic elements, it is a part of noise reducing device to be used along roads. Depending upon the design of the noise reducing device, structural elements may potentially be tested separately from acoustic elements.
They may be made of different materials for which specific standards are to be applied in accordance with the specifications prescribed hereafter. Some of the materials may contain dangerous substances, the reason why all the materials are declared.
This European Standard identifies the relevant characteristics of road traffic noise reducing devices, the corresponding methods of evaluation and specifies the provisions on evaluation of conformity and marking.

This European Standard is to give authorities, designers and specifiers information with respect to reaction to fire, smoke density and toxic fumes of materials used in noise reducing devices.
The combination of brushwood fire test, smoke density test and test for toxic fumes give in general enough safety information. This European Standard gives also information if more stringent requirements are requested for situations with a higher level of safety.
For noise reducing devices, this European Standard gives a method how to handle substantial components of non-homogeneous products (as defined in EN 13501-1 and ISO/DIS 5659-2:2016) and how to handle non-homogeneous products and in which cases the influence of non-substantial components on the total result of the classification may be neglected.
The following effects will be taken into account: ignitability, burning droplets, smoke growth rate, smoke density, toxic fumes.
The European Commission Decision 96/603/EC establish the list of products belonging to Classes A ‘No contribution to fire ’. The materials, and products made from them, that are listed in the Annex to this Decision, will, on account of their low level of combustibility and subject to the conditions also set out in the Annex, be classified in Classes A1 and Class A1FL as provided for in Tables 1 and 2 of the Annex to Decision 2000/147/EC. For the purpose of this classification, no reaction-to-fire testing of those materials and products made from them is required. The products considered having no contribution to fire are excluded from this standard.

This European Standard describes a test method for determining the intrinsic characteristics of sound diffraction of added devices installed on the top of traffic noise reducing devices. The test method prescribes measurements of the sound pressure level at several reference points near the top edge of a noise reducing device with and without the added device installed on its top. The effectiveness of the added device is calculated as the difference between the measured values with and without the added devices, correcting for any change in height (the method described gives the acoustic benefit over a simple barrier of the same height; however, in practice the added device can raise the height and this could provide additional screening depending on the source and receiver positions).
The test method is intended for the following applications:
•   preliminary qualification, outdoors or indoors, of added devices to be installed on noise reducing devices;
•   determination of sound diffraction index difference of added devices in actual use;
•   comparison of design specifications with actual performance data after the completion of the construction work;
•   verification of the long term performance of added devices (with a repeated application of the method);
•   interactive design process of new products, including the formulation of installation manuals.
The test method can be applied both in situ and on samples purposely built to be tested using the method described here.
Results are expressed as a function of frequency, in one-third octave bands between 100 Hz and 5 kHz. If it is not possible to get valid measurements results over the whole frequency range indicated, the results shall be given in the restricted frequency range and the reasons of the restriction(s) shall be clearly reported. A single-number rating is calculated from frequency data.
For indoors measurements see Annex A.
