This European standard 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 pendulum arm. The method provides a measure of the slip/skid resistance properties of a 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 non-homogeneous surface characteristics, e. g. containing ridges or grooves, or is rough textured (exceeding 1,2 mm patch test). NOTE 1 As the results from this test are taken at one small location, the results cannot be compared with results from devices e. g. mobile devices, that measure the slip/skid resistance over a long length of a surface. NOTE 2 The accuracy and precision of the test can be affected by the operative. The test should be carried out by a trained and competent person who has carried out the validation procedure in Annex A.1.
