Introduction: The retroreflection of a marking, in wet or rainy conditions, can be enhanced by special properties. The properties can be produced by surface texture (as with profiled markings), large glass beads or other means. In the case of surface texture, the passage of wheels can produce acoustic or vibration effects. |
||||
Scope: This standard specifies the performance for road users of white and yellow road markings, as expressed by their reflection in daylight and under road lighting, retroreflection in vehicle headlamp illumination, colour and skid resistance. |

Requirements: The requirements specified aim primarily at ther performance of road markings during their functional life. The requirements are expressed by several parameters representing different aspects of the performance of road markings and for some of these in terms of classes of increasing performance. Note 1: The length of the functional life depends on whether the road marking is of short or long durability, on whether or not the road marking is run on by traffic (e.g. symbols on the carriageway compared to continuous edgelines), on the traffic density, on the roughness of the road surface and on matters relating to local conditions such as the use of studded tyres in some countries. Note 2: The classes enable different priorities to be given to the different aspects of performance of road markings depending on particular circumstances. Classes of high performance cannot always be achieved for two or more of the parameters simultaneously. |
