The Australian standard “AS 4586 Slip resistance classification of new pedestrian surface materials” describes methods for testing new surface materials before installation. These methods cover both wet and dry conditions using laboratory equipment in controlled environments.
This standard is a key Australian standard that defines methods for assessing and classifying the friction properties of pavement and pedestrian surfaces. It helps manufacturers, architects, builders, and specifiers ensure surfaces are safe, particularly in wet conditions, by reducing the risk of slips and falls.
This standard replaces the previously published AS/NZS 4586 standard and focuses solely on new pedestrian surfaces (e.g., tile, concrete, vinyl, wood, or pre-installation coatings). It also complements the AS 4663 standard, which covers testing existing surfaces, and provides practical guidance on selecting appropriate ratings for different locations.
Slips, trips, and falls are leading causes of injury in both public and private spaces. Wet conditions caused by water, oil, or other contaminants significantly increase these risks. The AS 4586 standard supports compliance with accessibility standards such as the National Building Code (NCC) and AS 1428.1 by providing objective test methods for classifying materials.
The AS 4586 standard includes four basic test methods, each with different test approaches selected according to the expected use and contaminants:
The classification table (P-values) for the wet pendulum is as follows:
Higher P values (e.g., P5) indicate better slip resistance in wet conditions. The P rating shows how a surface performs when wet, which is when slips most frequently occur.
In general, the minimum recommended ratings for common locations such as these are as follows:
The latest update to the AS 4586 standard includes the following significant changes:
Under the National Building Code (NCC), certain areas (e.g., stair treads, ramps) require specific classifications. Tests must be approved by the Australian National Testing Authorities Association for reliability. Manufacturers typically provide certified reports for their products.
The AS 4586 standard plays a vital role in creating safer built environments across Australia, from homes to public spaces.
In short, this standard is crucial because slips, trips, and falls are a major public health and safety issue, causing thousands of injuries and significant economic costs each year. By providing objective, standardized testing methods for classifying the slip resistance of new flooring materials, this standard helps architects, builders, manufacturers, and property owners select surfaces that minimize slip risks, especially in wet conditions.
Without standardized tests, slippery surfaces (e.g., wet tiles or polished concrete) cannot be detected until accidents occur. The AS 4586 standard ensures that materials are evaluated using reliable methods, such as the wet pendulum test, which simulates real-world heel strikes on wet surfaces.
The National Building Code (NCC) mandates the use of non-slip surfaces in certain areas to ensure safe movement. Stair treads, edge trims, ramps, and landings must meet performance requirements. Compliance is typically indicated by AS 4586 classifications (e.g., minimum P4 or P5 ratings for high-risk areas).
For many years, our organization, with its competent and experienced staff, has been understanding the needs of its customers, providing the advanced testing services they require, and assisting in the establishment, implementation, and improvement of management systems. Within this framework, we also provide testing services to businesses in accordance with the "AS 4586 Classification of shear resistance of new pedestrian surface materials" standard.
