Over deze norm
Specifies requirements for signs;- non-retroreflective and retroreflective fixed signs;- for non-retroreflective and retroreflective fixed signs when they are illuminated at night by external lighting luminaires;and - for transilluminated signs. It defines performance limits and a range of performance classes for sign faces and supporting substrates, sign fixings and supports and external lighting luminaires. Colorimetric and retroreflective properties as well as the luminance of electrically illuminated signs are specified. The retroreflective properties are in respect of materials based on the use of glass bead technology only. Structural requirements for signs and sign support include performance under static and dynamic loading. It also defines performance levels to be maintained after artificial accelerated weathering and after natural weathering exposure in accordance with national annexes. Requirements for sign gantries and sign foundations are not included in this standard, nor are the passive safety performance requirements of signs and sign structures in case of vehicle impact.
