Slip Resistance Test Results
Measurement of Surface Slipperiness
A laboratory slipperiness assessment was undertaken by the Health & Safety Laboratory (UK) in accordance with guidelines recommended by United Kingdom Slip Resistance Group (Issue 2,2000) and protocols outlined in BS 7976:2.
Slip Risk Classification based on Pendulum Test Value
Pendulum Value [Slip Risk]
0 – 24 [High]
25 – 35 [Moderate]
36 – 64 [Low]
65+ [Extremely Low]
Pendulum measurements were taken in 3 directions for accurate assessments.

| Flat Sheet – Light Duty | 70/73/74 | 65-68-68 |
| Grating – Flat Surface 25mm | 62/65/68 | 47-45-49 |
| Grating – Gritted Surface 25mm | 71/79/68 | 71-74-60 |
Slip Risk Classification based on RZ Microroughness Values
(applicable for water-wet, low activity pedestrian areas)
RZ Surface Roughness (microns) Slip Risk
Below 10 High
10 or above (but below 20) Moderate
20 or above Low
Flat Sheet Heavy Duty and Light Duty
Data could not be generated due to the level of roughness exceeding the range of this instrument. This suggests the measurement would be at least 100 and therefore a low slip risk. Flat Surface Grating 25mm RZ Surface Roughness 12.06 (mean) = moderate potential for slip.
Gritted Grating 25mm
Data could not be generated due to the level of roughness exceeding the range of this instrument. This suggests the measurement would be at least 100 and therefore a low slip risk. The test results presented relate only to the flooring samples under study at the time of testing. The performance of installed materials may change significantly during their lifetime: slip resistance is critically dependent on the level and type of contamination, application of the surface treatment, wear, maintenance and effective cleaning subsequent to installation.
