Why test your floor?
Every tile loses its factory slip resistance over time and with use. A floor's appearance is not enough to judge its slip resistance: moisture, contamination and the way the floor is maintained all matter.
A measurement helps designers, investors, facility managers and administrators assess the surface and plan next steps.
How do we measure?
The British pendulum test gives the PTV (Pendulum Test Value). We match the test conditions and slider to how the surface is used.
- Measurements on dry and wet surfaces.
- Test points chosen for the type of facility.
- A report with results and a description of the test conditions.
- A walk-through of the results and next steps.
Measurement methods

British pendulum test (PTV)
The core slip resistance test, named in the guidelines of the Building Research Institute (ITB) and the Ministry. The pendulum's rubber slider mimics a pedestrian's step, and the result is given as a PTV.
How to read a PTV result?
Slip potential classification by the UK Health and Safety Executive (HSE).
| PTV value | Slip risk |
|---|---|
| 0-24 | High risk |
| 25-35 | Moderate risk |
| ≥ 36 | Low risk |
Frequently asked questions
We test the surface both dry and wet. Test conditions are matched to how the facility is used.
