7 Modification to 7.3, Luminance
st
Delete the 1 paragraph and replace with the following:
“The luminance shall be measured in accordance with 9.3.2, under external illumination from a solar simulator and
with the test module switched on. 'With settings prescribed by the manufacturer, the luminance values measured
for the test module shall comply with those of the Tables 4a to 4f that are relevant for the colours produced by the
test module."
Add the following new note: “NOTE 2 Specific design issues are covered in D.3, where guidelines are given on class
combinations.”

9 Modification to 7.5, Beam width
nd
Replace the 2 paragraph with the following:
“Within the beam width angles, the measured luminance shall not be lower than 50 % of the measured luminance
on the reference axis. Table 6 shows the seven beam width classes.”
Replace the Note with the following:
“NOTE 1 Figure 2 shows examples of passed and not passed luminance distributions for the white/yellow colour, class
luminance L3, and beam width class B2 at a sign illuminance of 40 000 lx.
NOTE 2 Specific design issues are covered in D.3, where guidelines are given on class combinations.”
In Figure 2, delete key 3) and renumber the rest.
After Figure 2 add the following new paragraph:
2
“The luminance for this colour at the reference axis should be in the range 10 540 to 52 700 cd/m . Suppose the
2
actual measured luminance at the reference axis obeys this requirement and is 30 000 cd/m . Then the maximum
2
luminance at all other angles is 1,5 ×× ××  30 000 = 45 000 cd/m . The minimum luminance at within the beam width
2
angles shall not be lower than 0,5 ×× ××  30 000 = 15 000 cd/m . Outside the beam width angles the luminance is
2
allowed to be zero, but never larger than 57 200 cd/m .”
