The project had five specific objectives relating to theoretical, practical and longer-term
aspects of harmonising skid resistance measurements in Europe, namely:
1. To improve the model on which EFI is based, which relates the friction coefficient
to the measurement speed, slip ratio and road surface texture, by taking account
of recent developments in this field.
2. To demonstrate the reliability and feasibility of the procedure proposed by
CEN/TC227/WG5 for inter-laboratory calibrations of the various devices used in
Europe.
3. To produce a revised draft standard incorporating the findings from items 1 & 2.
4. To provide FEHRL with a practical scheme for setting up an organisation for the
calibration of skid resistance devices in Europe.
5. To submit draft specifications for a reference device and/or reference surfaces to
the member laboratories of FEHRL with a view to developing the next generation
of standards.
The similarity algorithm calculates how much two contents in the system are similar to one another. So far, similarity is calculated based on similarity of the project type, area of interest and user type. Generally, if two contents have more parameters in common they are more similar to each another. More information.

While we are still building the FEHRLopedia with the help of experts like yourself, you may find that not all subjects are covered as deeply as you need. Therefore if you don't find the results you are looking for, please try the CERTAIN custom Google search. We would be grateful if you would create new content for the FEHRLopedia from your results. Thanks for your assistance in building the system.
