How Often Should You Be Testing? A Risk-Based Guide
How Often Is Often Enough?
Slip resistance should be tested routinely, not just once. Under AS 4663-2013, frequency depends on surface type, usage, and site risk—ranging from every 3 months in busy areas to annually in lower-risk environments. You should also test after any treatment, polish, near miss, or change in cleaning. This guide shows how to build a defensible testing schedule.
Slip resistance isn’t a one-and-done obligation—it’s an ongoing safety measure. Surfaces wear, coatings degrade, cleaning practices change, and so does your compliance status.
Australian Standard AS 4663-2013 is clear: pedestrian surfaces should be tested as they are used. That means post-installation, post-treatment, post-incident—and routinely over time.
But how often is “routinely”? That depends on your risk profile.
Suggested Testing Frequency by Surface Type
| Environment | Recommended Testing Interval |
|---|---|
| Shopping centres, hospitals, public foyers | Every 3–6 months |
| Office environments | Every 6–12 months |
| External walkways, entries, or ramps | Every 6–12 months & post-resurfacing |
| Sites with previous STF incidents | Next scheduled test, plus post-remediation |
| Surfaces with new sealants/coatings | Immediately post-treatment |
| Schools, universities, aged care | Every 12 months |
Trigger-Based Testing Is Just as Important
Even if you’re within your cycle, you should also test:
- After any polish, sealant, or resurfacing
- Following a near miss or injury event
- When cleaning regimes or chemicals change
- Before handover of new or refurbished zones
Why It Matters
Slips, trips & falls remain a top cause of injury claims in Australia. Regular testing gives you:
- Documented due diligence under WHS law
- Performance tracking over time
- A defensible position in claims or insurance reviews
- A reliable basis for flooring and cleaning decisions

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
