Quick answers about luminance contrast testing requirements in Australia.
Luminance contrast testing measures the difference in light reflectance between two adjacent surfaces — for example, a stair nosing and the adjoining tread. AS 1428.1 sets minimum contrast requirements for accessible buildings under the National Construction Code.
The National Construction Code (NCC) requires compliance with AS 1428.1 for all accessible commercial and public buildings. Testing is typically required at construction handover, after refurbishment, and for ongoing accessibility compliance audits.
Stair nosings, handrails, doors and accessible path transitions require minimum 30% luminance contrast under AS 1428.1. TGSIs have specific requirements under AS/NZS 1428.4.1 — integrated TGSIs require 30%, discrete TGSIs require 45%, and composite discrete TGSIs require 60% contrast compared to the adjacent path surface.
Under AS 1428.1, most accessible design elements require a minimum 30% LRV (Luminous Reflectance Value) contrast between adjacent surfaces. TGSI requirements vary — hazard and directional indicators have different requirements.
We use a calibrated 1-degree photometer held at 1.6 metres height. The Bowman-Sapolinski formula calculates the LRV difference between surfaces. For product classification, D65 illuminant and photometric measurement are used in the laboratory.
Reports are typically delivered within 24–48 hours of the site visit. Digital delivery is standard. Urgent turnaround may be available on request.
Luminance contrast and slip resistance testing are both required at construction handover. Sliptest Australia provides NATA-accredited slip resistance testing to AS 4586 and AS 4663 — the same organisation behind Luminance Test Australia.
