This part of EN 12899:2001 specifies requirements for new fixed signs :
non-retroreflective and retroreflective fixed signs ;
non-retroreflective and retroreflective fixed signs when they are illuminated at night by external lighting
luminaires ; and
transilluminated signs.
The main intended use of fixed signs is for the instruction and guidance of road users on public and private land.
It defines performance limits and a range of performance classes for both sign assemblies without vertical supports and assemblies complete with vertical supports, as well as sign faces and supporting substrates, sign fixings and supports and external lighting luminaires.
Colorimetric and retroreflective properties as well as the luminance 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 supports include performance under static and dynamic loading.
It also defines performance levels to be maintained after natural weathering exposure.
