Greetings from a floor that’s been tested
Slip testing across Cornwall
Independent, UKAS-accredited floor testing — grip measured wet and dry, by pendulum and surface roughness, with a report that proves a floor is safe.
PTV scale · 36+ = low risk
The postcard rack
The short version, card by card
Eight quick cards covering what matters — the methods, the verdict, the duty and the proof.
The pendulum (PTV)
Grip measured wet and dry with a calibrated pendulum — a Pendulum Test Value for every area.
How it works →Surface roughness (Rz)
Microscopic texture measured in microns — vital where floors get wet or greasy.
The method →The verdict
A clear low / moderate / high result. 36+ PTV, or Rz above 20, is the low-risk band.
Your duty
Keep floors safe and assess the risk — the HSW Act and the Workplace Regulations.
Care & the CQC
In care settings, the CQC expects slip risk to be actively managed.
Sectors →Independent
No ties to any flooring or treatment company, and no commission. Nothing nudges the number.

How readings are graded
| PTV result | Slip risk |
|---|---|
| 0–24 | High |
| 25–35 | Moderate |
| 36 + | Low |
| Surface roughness (Rz) | Slip risk |
|---|---|
| Below 10 | High |
| 10–20 | Moderate |
| Above 20 | Low |
