Luminance Contrast Testing

Independent luminance contrast testing of stair nosings, tactile ground surface indicators (TGSIs) and accessibility features for compliance with the National Construction Code and AS 1428.1.

Accessibility compliance you can certify

Luminance contrast measures the difference in light reflectance between adjacent surfaces — critical for people with low vision to safely identify stairs, ramps and hazards. The NCC and AS 1428.1 set minimum contrast requirements for stair nosings, TGSIs and glazing.

We test on-site and in the laboratory, wet and dry, and provide NATA-certified reports accepted by certifiers and access consultants. Reports are typically delivered within 24–48 hours.
