Photoluminescent materials have been around for many years but it is only in
the last couple of decades that their use has become widespread. The benefits
of “glow in the dark” substrates that emit light independent of direct electrical
0038/15
input are obvious, and these products have been seized upon by the safety sign
industry for their simplicity and effectiveness as a means of directing people
away from danger in times of power failure.
The use of photoluminescent signage has been mandated in the marine industry
since the early 1990’s but the events of the 9/11 terrorist attacks of 2001 led to a
wave of legislation regarding its use in land applications. Reports from fire crews
attending the World Trade Centre indicated that the use of photoluminescent
paint in the emergency stairwells contributed to the fast and effective evacuation
of thousands of people when other systems had failed. The message was clear;
photoluminescent products saved people’s lives.

Standards
The following standards are those most relevant to TELGLOW for use in
terrestrial applications.
BS ISO 16069:2017
Graphical Symbols – Safety Signs – Safety way
guidance systems (SWGS)
HARDINGTON
A safety way guidance system coordinates a complex range of safety products in
order to provide a continuous and conspicuous, unbroken route to safety that
allows people to evacuate occupied areas with minimum risk. ISO 16069 indicates
when and where it is appropriate to use photoluminescent materials as part of
an SWGS and defines minimum performance requirements for this application.
DIN 67510
Phosphorescent Pigments and Products
This German standard is the industry norm for the measurement and
assessment of photoluminescent products. DIN 67510 Part 1 defines a method
where samples are exposed for 5 minutes to a Xenon light source delivering
1000lux of light energy. The light is extinguished and the afterglow measured
in millicandella’s per m² (mcd/m²) at defined time intervals, until extinction is
achieved at a level of 0.32 mcd/m².
DIN 67510 Part 4 defines performance levels and is used by ISO16069 to
specify minimum performance requirements. When tested to DIN 67510-1
the photoluminescent must have a minimum luminance, after withdrawal of
the excitation light source, of 20 mcd/² at 10 minutes, 2.8 mcd/² at 60 minutes
and a minimum time to 0.32mcd/m² of 340 minutes. This information is usually
annotated as follows: 20/2.8 – 340 / DIN67510-1.
