LRV Testing & Luminance Contrast Assessments

Realm Access provides LRV testing services and luminance contrast assessments to ensure compliance with building code requirements.

Realm Access provides Luminance Reflectance Value (LRV) testing services and luminance contrast assessments to confirm compliance with the NCC building code requirements for stair nosing strips, tactile indicators (TGSIs), visual indication strips (glazing decals) and other building elements that must be provided with a minimum luminance contrast to ensure the built environment is safe and inclusive for everyone.

During the design phase we can test the LRVs of samples in-house – at our office or yours – to provide peace of mind the proposed finishes will achieve a compliant luminance contrast.

We also provide on-site testing of constructed works for final compliance sign-off, and as part of accessibility appraisals and access audits of existing buildings, sites and infrastructure.

Our service is prompt and personalised with fast turnaround times for reports and compliance certificates.

Our Process

Testing is carried out by our experienced access consulting staff who have the qualifications and knowledge to provide clients with specialist advice and guidance about minimum mandatory compliance requirements and best-practice.

Our testing equipment, a tristimulus colorimeter with a diffuse illumination/normal viewing (d/o) geometry and CIE Standard Illuminant D65, meets industry standards and the requirements of AS 1428.1 and AS/NZS 1428.4.1.

Did you know?

Many manufacturers and suppliers provide the LRVs for their products so if you already have the LRVs for your samples you can use our website’s free luminance contrast calculator to determine the luminance contrast.

Want to learn more about Luminance Contrast?

Luminance contrast is the amount of light reflected from one surface or component, compared to the amount of light reflected from another surface or component, typically expressed as a percentage. The amount of light reflected from each surface or component is referred to as the luminance reflectance value (LRV), although it is sometimes also called the light reflectance value or luminous reflectance value.

Very few people with vision impairments have no vision at all; many have some vision and can perceive light, shade and reflections. Ensuring certain elements of the built environment are provided with sufficient luminance contrast can greatly enhance safety and legibility for people with vision impairments.

And it’s not just beneficial to people with vision impairments. Many people can benefit from thoughtful design in relation to luminance contrast including:

  • people who are colourblind

  • people who have cognitive impairments such as dementia

  • people with sensory and neurological sensitivities including vertigo, disorientation and seizures

  • people who are deaf or who are hard of hearing, and people who rely on visual communication such as lip reading and sign language
