Standards Development

Scope

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

Purpose

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
