PD CEN TS 17812:2022

This standard PD CEN TS 17812:2022 Determination of the acoustic properties of markings. The CPX measurement method is classified in these ICS categories:

• 17.140.30 Noise emitted by means of transport
• 93.080.30 Road equipment and installations

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.
