Light Reflectance Testing
The provision of TGSIs, stair nosing and braille signage with sufficient luminance contrast enhances accessibility for all people, especially for those with vision impairment, and is now a regulatory requirement.
Luminance contrast compares the difference in the amount of light reflected (luminous reflectance) from a TGSI, stair nosing or braille sign with that of its surrounding substrate. Contrast difference percentages are specified in regulatory standards and the correct contrast difference must be confirmed for every location. At Korb, our technical staff are equipped with a state of the art tristimulus colorimeter. We offer on-site testing and advice with a detailed luminance contrast report to help you achieve compliant luminance contrast requirements.
