Risk by Design: Why Post-Install Testing Matters as Much as Pre-Check
Why Post-Install Slip Testing Is Essential
Lab test results don’t reflect real-world conditions. AS 4663–2013 testing is just as important post-install as pre-check to verify slip resistance under actual usage. What passes in the lab might fail on site.
A tile with a compliant P-rating in the lab can still become hazardous once installed. It might be sealed, polished, cleaned with aggressive products, or installed on a slope. Foot traffic and weather can also wear down the surface faster than expected.
That’s why AS 4663–2013 exists. This in-situ standard measures the slip resistance of the actual floor as installed, not just the product in isolation. Where AS 4586–2013 tests the material in the lab, AS 4663–2013 confirms how that surface performs in real life.
Common risk factors post-install:
- Sealers that reduce surface roughness
- High-gloss polish applied after handover
- Textured finishes worn down by traffic
- Cleaning practices that leave a film or change friction
In many cases, a surface that was P4 in the lab can test as P2 on site. This creates exposure for building owners, tenants, and facilities teams. It may also void insurance or fail WHS audits.

Should You Test with TRL or 4S Rubber?
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
Sample Prep 101: What We Need – and What to Avoid
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
How to Certify a Product Line: Don’t Stop at One Tile
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
