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.

Slip Test Lab

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.

Retail Floors: The High-Risk Zones You’re Overlooking

Retail floors

Retail floors often look clean and polished—but that doesn’t mean they’re compliant. Entry tiles, produce aisles, and checkouts are frequent failure zones under AS 4663:2013. This article explains where retail slip risks occur, what HB198:2014 requires, and how to test against real-world conditions.

Can You Fail a Slip Test? Yes — Here’s Why

Can you Fail a Slip Test

Surfaces can and do fail slip resistance tests—both in lab and onsite. Whether it’s a new tile rated under AS 4586:2013 or a worn floor checked to AS 4663:2013, results often fall short of what’s needed. This article explains why failure occurs, what happens next, and how to stay compliant.
