Should You Test with TRL or 4S Rubber?

TRL vs 4S slip test

Not all slip tests are equal – the slider you choose changes the result. AS 4586–2013 wet pendulum testing uses 4S rubber for general footwear and TRL rubber for barefoot or soft sole zones. A P4 with 4S might drop to P2 with TRL. Choosing the right slider is critical for valid, compliant results.

Sample Prep 101: What We Need – and What to Avoid

Sample Prep: What to Send

Sample quality drives valid AS 4586–2013 results. Send a minimum 200 × 200 mm tile per finish, clearly labeled and packed flat on a rigid backing so it can’t move or break in transit. Disclose any seals or coatings and note slider preferences (Slider 96/4S, Slider 55/TRL). Our Sample Prep Checklist prevents delays and protects your data.

How to Certify a Product Line: Don’t Stop at One Tile

Certifying product ranges AS4586-2013

Certifying one tile finish doesn’t cover the rest of the range. Under AS 4586–2013, gloss, matt, honed, or sealed tiles may all deliver different slip ratings. Zerofal helps structure bundled tests so each finish is properly certified—protecting your brand and giving specifiers confidence.

Why Your Last Test Might Be Outdated

Why your last slip test might be outdated

A slip resistance certificate only applies to the exact batch tested. Even if the product looks identical, a different batch must be tested separately. Add in wear, cleaning changes, coatings, or weather – and your last result may no longer be valid. Routine AS 4663–2013 retesting protects compliance and ensures WHS risks are managed.

Education: Schools, TAFEs & Transitional Zones

Slip testing in schools

Schools and TAFEs manage diverse surfaces—wet entries, ramps, stairwells, and older repairs—all prone to slip risk. AS 4663–2013 testing measures how these surfaces perform today, helping WHS teams track degradation, justify budgets, and prevent incidents. Zerofal provides structured, site-wide testing plans to support compliance and keep students, staff, and visitors safe.

P and D ratings under AS 4586:2013 define how a surface performs under wet or dry conditions. This guide explains the testing methods, classification scales, and how to ensure your product or floor is compliant before installation.

How Often Should You Be Testing? A Risk-Based Guide

How often should you be testing?

Slip resistance isn’t static. Wear, cleaning, and treatment changes can all affect safety. This guide outlines how often you should be testing surfaces under AS 4663:2013—based on risk, site type, and real-world triggers.
