Overview
Procedures and methods that are used for application of materials and performance measurements are specified. The Nordic certification system for road marking materials was introduced in 2015. The system is based on documented performance measurements of material samples applied on test fields on public roads.
From 2016, the certification system includes both flat (type I) and structured/profiled (type II) markings. The certification system is based on the European standards EN 1824 Road marking materials – Road trials, EN 1436 Road marking materials – Road marking performance for road users, and EN 12802 Road marking materials – Laboratory methods for identification. Material tests are carried out at two test sites: one in Sweden and one in Denmark.
The report describes the certification system for road marking materials and how it is applied in the Nordic countries.
The certification includes requirements on coefficient of retro reflected luminance RL under dry and wet conditions, luminance coefficient under diffuse illumination Qd, friction and colour coordinates. The number of wheel passages are measured at the test sites annually. The certification system includes material identification, which allows for future material sampling and analysis.
Results
Product approval is based on monitored and documented performance measurements of material samples applied on test fields on public roads. The present report describes the certification system and the road trials. In the first stage, the certification system applies for the countries of Norway, Denmark and Sweden. Finland will not apply the certification system in this first stage, but may join later.
The guidelines and procedures related to the certification system have been developed by a working group.
