WHAT DO P AND D RATINGS MEAN IN AS 4586:2013 LABORATORY TESTING?

P and D ratings are laboratory classifications produced by different AS 4586:2013 test methods. Learn what each rating means and why they are not interchangeable.
CAN AN AS 4663:2013 RESULT BE CONVERTED INTO AN AS 4586:2013 P RATING?

An AS 4663:2013 result for an existing surface should not be converted into an AS 4586:2013 P rating. Learn why the Standards produce different forms of evidence.
SRV, BPN and P Ratings: What Is the Difference?

BPN, SRV and P rating are related to pendulum slip testing, but they do not mean the same thing. Learn which terms describe readings, results and classifications.
What does a wet pendulum slip test result mean under AS 4663:2013?

A wet pendulum test produces a numerical result, but that number is not a complete risk assessment or an AS 4586:2013 P rating. Learn how to interpret an AS 4663:2013 result for an existing pedestrian surface.
What should suppliers test before outdoor surfaces are installed?

Outdoor pedestrian products should be tested before installation where wet use is expected. AS 4586:2013 testing helps confirm suitability before site risk begins.
When should wet pendulum testing be used instead of dry floor testing?

Wet pendulum and dry floor testing answer different questions. The correct method depends on whether the surface is expected to be wet or dry in real use.
Why does slip risk increase in winter?

Winter exposes surfaces that may perform adequately when dry but become slippery when wet, contaminated or slow to dry. Testing confirms real performance.
Can painted surfaces become more slippery when wet?

Painted walkways, crossings, accessible bays and line markings can become more slippery when wet. Testing under AS 4663:2013 confirms how the surface performs in real conditions.
Car Parks: The Overlooked Slip Risk in Commercial Properties

Undercover and external car parks are increasingly becoming high-risk pedestrian environments due to worn coatings, contamination, moisture and reduced cleaning attention. Learn how slip resistance testing under AS 4663:2013 helps identify hidden risk before incidents occur.
