Sliptest Australia provides professional on-site luminance contrast testing to verify accessibility compliance with Australian Standard AS 1428.1 – Design for Access and Mobility.
Luminance contrast testing measures the difference in light reflectance between adjacent surfaces to ensure that building elements can be clearly identified by people with vision impairment.
This testing is commonly required for building certification, accessibility compliance and construction handover documentation.
Why Luminance Contrast Matters
Correct luminance contrast allows visually impaired pedestrians to safely identify:
- changes in level
- stair edges
- accessible paths of travel
- tactile indicators
- obstacles and hazards
Where insufficient contrast exists, surfaces may not comply with accessibility requirements under the National Construction Code (NCC).
Testing verifies whether surfaces provide the required level of visual contrast.
What We Test
Sliptest Australia conducts luminance contrast testing across a wide range of building elements including:
Stairways
- Stair nosing contrast
- Step edge identification
- Stairway visibility.
Tactile Ground Surface Indicators (TGSI)
Luminance contrast between tactile indicators and surrounding surface.
Handrails
Handrail contrast against walls or backgrounds.
Doors and Accessible Pathways
- Door frame contrast
- Accessible pathway elements.
Other Accessibility Elements
- Lift lobbies
- Ramps and landings
- Circulation spaces
Equipment Used
Testing is performed using professional luminance measurement equipment, including:
- Konica Minolta luminance meters
- Konica Minolta colour analysers
These instruments measure the luminance values of adjacent surfaces, allowing accurate calculation of luminance contrast ratios required for accessibility assessment.
When Luminance Testing is Required
Luminance contrast testing is typically requested during:
- building completion and handover
- accessibility compliance verification
- certification inspections
- rectification assessments
- refurbishment of existing buildings
Architects, access consultants, certifiers and builders often require testing to confirm that building elements meet AS 1428.1 accessibility requirements.
Reporting
Following testing, Sliptest Australia provides a clear and detailed test report outlining:
- luminance measurements recorded on site
- calculated contrast ratios
- tested building elements
- photographic references where required
Reports are typically issued within 24 to 48 hours of testing.
Combined Compliance Testing
Sliptest Australia also conducts:
- slip resistance testing (AS 4586 and AS 4663)
- luminance contrast testing (AS 1428.1)
This allows project teams to verify both slip safety and accessibility compliance during construction and building handover.
Service Areas
Sliptest Australia provides testing services across:
- Queensland
- New South Wales
Testing is performed on commercial buildings, retail centres, public facilities, infrastructure projects and residential developments.
