Standards Development
This document specifies requirements and test methods for fixed signs (non-retroflective fixed signs, as: fixed signs with non-retroreflective sign face material, trans-illuminated fixed signs or externally illuminated fixed signs and retroflective fixed signs, as: fixed signs with retroreflective sign face material, trans-illuminated fixed signs, or externally illuminated fixed signs) including the electrical components of the illuminated signs.
This standard covers a number of different performance requirements that have to be fulfilled (visual performance, resistance to horizontal loads, etc.), but also issues of lifetime (durability) are covered.
This standard does not cover:
• signs with discontinuous messages, e.g. using light emitting diodes (LED, or fibre optics),
• variable message signs,
• signs used for temporary purposes,
• test for extremely low temperature
The EN 12899 series is composed of:
- 3 product standards (EN 12899-1, EN 12899-2 and EN 12899-3)
- 2 testing and control standards (EN 12899-4 and 12899-5)
The aim of the revision is:
- to technically update the standard series
- to merged testing and control standards into each product standard
- to split the EN 12899-1 into 4 different parts (EN 12899-1-1, EN 12899-1-2, EN 12899-1-3, and EN 12899-1-4)
- to include micro-prismatic sheets (so far under EAD)
- Adaptation to the CPR
Note: in case the WI is based on documents from other organizations than ISO/IEC, please specify it here
