Slip Resistance Explained

Slip-Resistance Explained 

AS 4586 and AS 4663

The Australian Standard for slip resistance includes a wet pendulum slip test for both new and existing surfaces. The standards are AS 4586:2013 Slip resistance classification of new pedestrian surface materials and AS 4663:2013 Slip resistance measurement of existing pedestrian surfaces.

For both tests, two different type of sliders are used. Firstly, slider 96 is used for pedestrian surfaces. Secondly, slider 55 is used to test the slip resistance for barefoot surfaces (bathrooms, pools, etc.). Therefore, Slider 55 is softer and resembles the skin of our feet, whereas Slider 96 is rubbery and resembles a shoe sole. To conduct a valid test, five measurements are taken and the combined average of these tests provide a Slip Resistance Value (SRV), which in return provides a wet pendulum class.

Wet Pendulum Class SRV Slider 55 SRV Slider 96 Risk of Slips
P0 < 12
P1 < 20 12 → 24 Very High
P2 20 → 34 25 → 34 High
P3 35 → 39 35 → 44 Moderate
P4 40 → 44 45 → 54 Low
P5 > 44 > 54 Very Low

Wet barefoot inclining platform slip-resistance (Appendix C of AS4586)

In this test, a sample is mounted on an inclining platform surface. Next, a person in a safety harness will walk up and down on the surface while water is sprayed on the surface. The angle of the inclining platform is raised until the test person feels that walking will result in slipping. From several tests, the mean angle of inclination determines the slip-resistance rating.

Results are categorised into three classes:

Wet Inclining Platform Test Angle Slipping Risk
A ≥12° High
B ≥18° Medium
C ≥ 24° Low

Oil wet inclining platform slip-resistance (Appendix D of AS4586)

This test is designed for industrial surfaces, but often used to indicate the slip-rating of tiles. The test uses the same equipment as described above, however motor oil replaces water as the wetting agent and safety boots are worn on the feet.

Oil Inclining Platform Test Angle
R9 ≥6° & ≤ 10°
R10 ≥10° & ≤ 19°
R11  ≥19° & ≤ 27°
R12 ≥27° & ≤ 35°
R13 ≥35°.

R-Ratings are often used by tile manufacturers to indicate the slip rating of their tiles. However, this is often only an indication. Rarely are the tiles tested by an independent institution for their slip-rating. This is one of the main reasons why tiles that were supposed to be non-slip fail an independent test after installation. This problem occurs especially when the surface is tested in wet or oily conditions (how it should be tested).

Because the platform or ramp tests is conducted by a person and not by a “machine” like the wet-pendulum test, it has been debated if is a good test to measure the slip-resistance of a surface.

Slip Resistance Requirements

The CSIRO/Standards Australia Handbook (HB198:2014) provides recommendations for what degree of slip-resistance is required for different uses, areas and environments.

Exceeding slip resistance standards

To completely reduce slips and falls, Swiss GriP gives you the possibility to exceed the required slip-resistance standard without creating a rough of unappealing surface. Our coatings are CSIRO certified with P5 and R11 and R12 Slip-Ratings.

Because Swiss GriP is independently certified by CSIRO in accordance to AS 4586-2013, you will know upfront which slip rating your floor will achieve after Swiss GriP is installed. To get a precise result it is possible to have your new Swiss GriP surface tested in accordance to AS 4663:2013.

No P4 Slip-Rating? No Pay 

What sets Swiss GriP apart from anti-slip treatments is that we guarantee your floor will comply with the regulations after the installation. If Swiss GriP does not reach a minimum of a P4 slip-rating in an independent slip-test in accordance to AS 4663, you don’t have to pay for the Swiss GriP Coating.

    Swiss GriP Non-Slip: Independently Certified

    Unlike anti-slip treatments, Swiss GriP is certified by independent institutions like CSIRO Australia with the best possible slip-resistance ratings. This means our coatings not only eliminate the risk of slips and falls, they also provide protection against liability claims.
