Slip Resistance
Interpreting pendulum test results
How to interpret your pendulum method wet test report:
- Compare the test location description from your test report to the Dubai Universal Design Code (Table 2) descriptions below...identify the most appropriate comparable environment to determine performance.
- Compare the Pendulum Test Value (PTV) result for location reported to the identified recommended PTV...note if the test area's reported outcome meets, exceeds, or is found to be underperfroming to the Dubai Universal Design Code
* Table 2. Pavement slip resistance
Pavement Slip Resistance
| Floor Pavement Slopes | Pendulum Test Value (PTV) |
|---|---|
| Dry Areas Indoor | |
| Level Surface | Between 15 and 35 |
| Inclined surfaces with slopes less than 5% | |
| Inclined surfaces with 5% slopes or greater | 35 or more |
| Wet Areas Indoor and Outdoor | |
| Level Surface | Between 35 and 45 |
| Inclined surfaces with slopes less than 5% | |
| Inclined surfaces with 5% slopes or greater | 45 or more |
| Streets pavement, swimming pools and showers | 45 or more |
Treatment Options
For surfaces that achieve a BPN result below the recommendations the following are options available to increase slip resistance and Reduce Your Risk!
- Cleaning procedures
- Detergent residues can build up over time with heavy detergent use.
- Acid etching
- For tiled surfaces. Can vary in performance with different tile types.
- Wet sand/ Soda blasting
- To obtain a textured finish to tiles and other hard surfaces (may require sealing).
- Shot blasting
- More extreme treatment to wet sandblasting (may require sealing).
- Textured coatings
- Ensure a consistent texture is achieved.
- Surface replacement
- Replacement surface may be the most cost-effective option in some locations.
An internet search for 'flooring treatments' will identify surface treatment professionals in your local area. ISTS recommends sourcing a number of detailed proposals when considering treatments, outlining expected slip resistance improvements, visual changes, cleanability, and life expectancy.
