A Nordic certification system, NordicCert, applies to the countries of Denmark, Iceland, Norway, and Sweden. The certification system implies that a documented product approval is required to use a road marking material on roads managed by the national road authorities. Product approval is based on monitored and documented performance measurements of material samples applied on test fields on public roads.
This report documents the results of the initial performance measurements of materials applied at the Danish test site in 2022. In total, ten materials were applied, all as certification materials, which means that all materials participated in the test with the purpose of being certified for use on roads managed by the Danish Road Directorate.
Performance measurements of coefficient of retroreflected luminance RL under dry and wet conditions, luminance coefficient under diffuse illumination Qd, chromaticity in daylight, and friction were carried out approximately two weeks after application. The aim of these initial measurements was to determine whether the materials qualify for continued participation in the road trials.
Seven out of the ten certification materials were approved for continued participation. Three materialswere disqualified because the requirement on friction was not fulfilled.
