BS EN 1569 A steel test wheel, of diameter (100土1) mm and width (30,0土0,3) mm with the edges rounded to a radius of(1土0,1) mm.A rigid plate, for example of steel or timber, of minimum thickness 50 mm, with two supporting wheels, in addition to the test wheel.A means of moving the apparatus backwards and forwards over the test specimen at a velocity of approximately 1 m/s. This may be achieved by manual movement using a metronome or similar to set the pace of movement or by mechanical means such as an automated drive system.Weights, positioned such that the centre of gravity of the apparatus is directly over the axle of the test wheel. The test wheel is loaded with a force as given in the product specification or as agreed between the interested parties. The load on the supporting wheels is not greater than 50 N.  Two guide tracks at least 5 mm high by 700 mm long that can be temporarily, but securely, mounted (e.g. using double-sided adhesive tape) 50 mm apart to the test specimen to ensure the test wheel always passes over the same area.If an automated test rig is used where the sample trolley is moved mechanically the test tracks are not required.  A means of measuring residual indentation to +0,1 mm.Prepare a specimen of surface of minimum length 1 500 mm and minimum width 1 500 mm, in combination with the supporting layers with which it is to be used in service, using the recommended method of attachment in accordance with the manufacturer’s instructions.Attach the guide tracks along the critical area of the test piece so they are 50 mm + 0/-5 mm apart and at least 100 mm from the edge of the test specimen. Locate the test wheel within the guide tracks and roll the apparatus forwards and back over the critical areas of the test piece at a velocity of approximately 1 m/s within a test strip of 50 mm width 300 times as illustrated in Figure 2.BS EN 1569 pdf download.
