Road and airfield surface characteristics - Test methods - Part 4: Method for measurement of slip/skid resistance of a surface: The pendulum test

Scope

This document describes a method for determining the slip/skid resistance of a surface using a
device which remains stationary at the test location. The slip/skid resistance is measured by
means of a slider mounted at the end of a pendulum arm.
The method provides a measure of the slip/skid resistance properties of a wetted surface either
in the field or in the laboratory.
This method measures the slip/skid resistance of a small area of a surface (approximately 0,01
m²). This should be considered when deciding its applicability to a surface which may have nonhomogeneous
surface characteristics, e.g. containing ridges or grooves, or is rough textured
(exceeding 1,5 mm mean texture depth).
