- In case of doubt, the trichromatic coordinates for the most selective sample shall be determined.
- Expressed in CIE trichromatic coordinates, the light of the beams shall be in the following boundaries:
- If any doubt remains after this test, conformity with the colorimetric specification shall be verified by determining the trichromatic coordinates of the most doubtful sample.
- The colour of the light emitted shall be white. Expressed in CIE trichromatic coordinates, the light of the beams shall be in the following boundaries:
- If any doubt remains after this test, compliance with the colorimetric specifications shall be verified by determining the trichromatic coordinates of the most doubtful sample.
- Expressed in CIE trichromatic coordinates, the light of the beams shall be within the following boundaries: limit towards blue x ≥ 0,310
- This shall be verified by the visual comparison test indicated above, the control field being illuminated by a light source of which the trichromatic coordinates differ by 0,01 from that of standard illuminant A.
- When the retro-reflecting device is illuminated by ICI standard illuminant A, with an angle of divergence of 1/3° and an illumination angle of V = H = 0°, or, if this produces a colourless surface reflection, an angle V = ± 5°, H = 0°, the trichromatic coordinates of the reflected luminous flux must be within the following limits: ≤
- Clear retro-reflecting devices must not produce a selective reflection, that is to say, the trichromatic coordinates ‘x’ and ‘y’ of the standard illuminant ‘A’ used to illuminate the retro-reflecting device must not undergo a change of more than 0,01 after reflection by the retro-reflecting device.
