Australian Standards AS1428.1 & AS/NZS1428.4.1 require laboratory luminance contrasts testing to be carried out with a specific measuring device. To quote the Standards –
B3.2 Instrumentation “A tristimulus colorimeter, or spectrophotometer with a diffuse illumination/normal viewing (d/o) geometry, is used with CIE Standard Illuminant D65. The instrument has to be capable of measuring absolute CIE for Yxy to be calculated. The measured luminous reflectance is defined by the tristimulus value Y. The chromaticity coordinates x and y provide an indication of the colour.”
The testing done by Luminos Consulting will comply with the Australian Standards. These tests are conducting by using only compliant geometric equipment and we provide equipment detail reports as required in the Standards. It is important to note that there is NO Spectrophotometer that will meet the Standards Requirements.
All of our on-site luminance contrast testing is performed using the equipment stated in AS1428.1 & AS/NZS1428.4.1, a single reflex lens photometer. The testing conducted on TGSI’s is always in compliance with the set requirements of AS/NZS1428.4.1 and all other building elements as per AS1428.1.
Please note that at Luminos Consulting, we are able to conduct tests at any location and we always supply our luminance contrast reports 24 hours after the test completion.
Both the laboratory and the onsite luminance contrast testing includes both dry and wet luminance contrast ratios.
