AS 4586: Slip Resistance Classification of Pedestrian Surface Materials
Slip and fall incidents are a leading cause of injury in commercial and public buildings. AS 4586 is the Australian Standard that classifies the slip resistance of pedestrian surface materials — and understanding it is essential for anyone specifying flooring in healthcare, education, hospitality, or any public-access environment.
01.What Is AS 4586?
AS 4586 (Slip resistance classification of new pedestrian surface materials) provides a classification system for the slip resistance of floor surfaces. It defines test methods and classification categories that allow specifiers to compare products and select appropriate surfaces for different applications and risk levels.
02.Classification Systems: P-Ratings and R-Ratings
AS 4586 uses two primary classification systems. The Wet Pendulum Test produces P-ratings (P1 through P5), where higher numbers indicate greater slip resistance in wet conditions. The Oil-Wet Ramp Test produces R-ratings (R9 through R13), used primarily for industrial and commercial kitchen environments. A separate classification (A, B, C) applies to step nosings and ramps tested using the Wet Barefoot Ramp Test.
03.Minimum Requirements by Application
The Building Code of Australia (BCA/NCC) references AS 4586 and specifies minimum slip resistance classifications for different building types and locations. Wet areas such as bathrooms and commercial kitchens typically require P4 or P5. Ramps require higher ratings. Healthcare corridors and aged care facilities generally require P3 or above. Dry internal areas may be acceptable at P1 or P2, though specifiers often exceed minimums for risk management.
04.Healthcare and Aged Care Considerations
In healthcare and aged care environments, slip resistance is a critical safety requirement. Floors must perform in both dry and wet conditions — including cleaning with water and chemical agents. Safety vinyl products specifically designed for healthcare applications typically achieve P4 or P5 ratings and are tested to confirm performance is maintained after cleaning. Specifiers should request test certificates from manufacturers.
05.Maintenance and Slip Resistance
It is important to note that AS 4586 classifies new materials. Slip resistance can change over time due to wear, contamination, and the use of inappropriate cleaning products or floor finishes. Facility managers should ensure that cleaning regimes are compatible with the flooring product and that slip resistance is periodically assessed, particularly in high-traffic wet areas.
06.Specifying Slip-Resistant Flooring
When specifying flooring for commercial projects, always request AS 4586 test certificates from the manufacturer and confirm that the classification meets or exceeds the requirements for your application. Mac Flooring Australia can advise on appropriate products for your specific environment and risk profile.
