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
At Zerofal, we provide routine site testing under AS 4663-2013, using wet pendulum and dry friction methods. We’ll help you set a testing schedule, interpret results, and reduce risk—before someone gets hurt.
Not sure when you last tested? It might be time.
