Nordic certification system for road marking materials: Version 10:2024

A 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. The certification system includes both flat (type I) and structured/profiled (type II) markings, antiskid materials (materials with enhanced friction), temporary markings, inlaid markings (Norway only), materials for hand application and materials with enhanced durability for illuminated high-traffic urban areas. Material tests are carried out at two test sites: one in Norway and one in Denmark. The test fields are situated on public roads and the tested materials are thus exposed to real traffic conditions and to weather conditions representative for the Nordic countries. The materials are followed up by performance measurements for one or two years. The certification includes requirements on coefficient of retroreflected luminance RL under dry and wet conditions, luminance coefficient under diffuse illumination Qd, friction and chromaticity coordinates. The number of wheel passages is measured at the test sites annually. The certification system includes material identification, to verify that the manufacturer’s declaration of constituents agrees with the material applied on the test field. 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, EN 12802 Road marking materials – Laboratory methods for identification, and EN 1423 Road marking materials – Drop on materials – Glass beads, antiskid aggregates and mixtures of the two. This document constitutes the guidelines for the Nordic certification system. The document describes the certification procedure, what type of products that are included in the system and the requirements for certification. Furthermore, the procedures and methods used for application of materials, performance measurement and identification analysis are described. The document also gives specifications and practical information regarding the test sites and regarding registration and application of products for certification. Ett nordiskt certifieringssystem för vägmarkeringsmaterial introducerades under 2015. Systemet baseras på dokumenterade materialtester på provfält, där materialen certifieras utifrån hur många hjulpassager de klarar. Certifieringssystemet omfattar både plana (typ I) och profilerade/våtsy
