Slip resistance testing: Adelaide’s NATA-accredited laboratory

Our NATA-accredited laboratory is run by skilled technicians who help solve problems and minimise the risk of trips and falls in your project. Our Adelaide-based slip testing team is certified to test to AS 4586:2013 (New Pedestrian Surfaces) and AS 4663:2013 (Existing Pedestrian Surfaces). We offer same-day slip testing* for Adelaide projects (we test Australia-wide).

The experienced technicians at Stone Initiatives can help to ensure your surfaces meet the relevant Australian Standards, and determine compliance with relevant requirements of the National Construction Code. We’ve also developed a suite of in-house testing methods to help determine fitness for use.

Our services are fast, efficient and reliable. With more than thirty years of experience in determining slip resistance, we are the only NATA-accredited laboratory in Australia that specialises in dimension stone.

How is slip resistance tested?

In Australia and New Zealand slip resistance is measured according to two different (but similar) standards, depending on whether the surface is new or existing. New pedestrian surfaces are slip tested in accordance with the current version of AS 4586, while existing pedestrian surface are tested in accordance with AS 4663.

Stone Initiatives is Australia’s only NATA-accredited laboratory specialising in dimension stone. Our experienced technicians can help to ensure your project or flooring sample meets Australian Standards related to slip resistance, and we can also test to determine compliance with the slip resistance requirements of the National Construction Code.

Relevant tests

Wet Pendulum – Slip Resistance – AS4586:2013 & AS4663:2013
Dry Floor Friction testing – AS4586:13 & AS4663:2013
Skid Resistance – DTEI TP345
Accelerated Wear Testing – SI-AWT-2016

Why choose us for slip testing in Adelaide and Australia-wide?

Our Adelaide-based team can test for the slip resistance of your existing project on site in Adelaide or anywhere in Australia, or you can send surface samples to be slip tested in our NATA-accredited lab here in Adelaide. Our staff have more than 30 years of experience in determining slip resistance for tiles, flooring systems and other pedestrian surfaces. We are skilled and experienced trouble-shooters backed by a laboratory that can provide additional services related to pedestrian surface finishes – this makes solving problems and minimising risk in your project quicker, easier and stress free. See more reasons here.

*Same-day testing is available for Adelaide-based projects, subject to availability, Call-out fees may apply.

“Complying with slip resistance requirements can be difficult – what works for one location and surface type might not work for another. On top of that, our clients often have the challenge of meeting the project’s aesthetic requirements. In addition to slip testing, we are often called on to utilise our experience and recommend alternative finishes that might achieve the desired aesthetics.”

Why choose us for slip testing in Adelaide and Australia-wide?

Determining slip resistance after accelerated wear is becoming a critical part of testing programs, especially with so many new developments using stone flooring. Builders and Project Managers are needing to know if their chosen stone flooring will hold up to daily wear and tear and not become a costly hazard. Stone Initiatives performs standard accelerated wear testing to method SI-AWT:2016 that incorporates AS4586:2013 and is recognised by NATA. If you think your new stone flooring may be at risk of becoming a slip hazard, please contact our Adelaide lab for more information.

Measurement of wet slip resistance: Wet Pendulum Test

The Pendulum method measures the frictional resistance between a rubber slider mounted on the end of a pendulum arm and the test surface. The pendulum consists of an arm that rotates about a spindle attached to a vertical support pillar. At the other end of the arm is a mass (shaped like a foot) fitted with a spring-loaded rubber slider. The pendulum is locked into a horizontal position and then released so that it strikes the sample surface over a set distance with a constant velocity and energy. The pendulum continues its arc past the strike path and the height of the forward swing is determined by the energy lost due to friction when in contact with the sample surface. A pointer is pushed along by the pendulum and records the height of the swing. A reading is recorded from the scale and recorded as the British Pendulum Number (BPN). The mean BPN is calculated to give the slip resistance value (SRV).

A guide to slip resistance recommendations for location types*

Type of locationLocation Example for P5 to P0 classifications according to HB198:2014 Pendulum Classification AS 4586-2013BPN Range
