At the international level, several methods exist to measure the slippage of pavements. At European level CEN / TS 16165, Determination of resistance to slippage of pedestrian surfaces is currently being studied. Methods of evaluation.
This is a specification describing the test methods used in Europe for the
determination of the slip resistance value on pedestrian surfaces. Attachments are generated in which each of the methods are described:
- Annex A: Ramp method with the application of water as pollutant and bare feet
- Annex B: Ramp method with the introduction of oil as a contaminant and footwear.
- Annex C: Test method based on the friction pendulum, dry and wet.
- Annex D: Method based on the dry and wet tribometer
Several countries, including Spain, voted against this specification on the grounds that no single test method is established and allows each country to use the test method it considers without reaching consensus among the parties.
