Light Reflective Value Calculator
As set out in the Australian Standards 1428, It is a requirement that all Braille Signs achieve a minimum 30% contrast to the background they are mounted on.
We have had all our signs externally tested in controlled conditions to determine Light Reflective Values (LRV) to ensure our customers have all the information required to ensure compliance is met.
To Use Our LRV Calculator
First enter the Light Reflective Value (LRV) of the sign you will be installing into our Calculator along with the Light Reflective Value (LRV) of the substrate the sign will be installed on. The calculator will let you know if the minimum 30% is Achieved. Our LRV scores for each sign type can be found in the header description of each product categories or in each individual product description. Most Paint Suppliers will also supply LRV scores for their products, this can normally be found on their web site.
