BS EN 13036-4:2011EN 13036-4:2011 (E) 4 1 Scope This European Standard describes a method for determining the s

25、lip/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 surface either in the field or in t

26、he 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 (e

27、xceeding 1,2 mm mean texture depth). NOTE 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. 2 Normative references The following reference

NOTE 2 There are numerous factors which contribute to skid resistance, including the tyre pressure, contact area, tread pattern and rubber composition of the tyre or sole; the alignment, texture and frictional characteristics of the surface; the vehicle speed; the weather conditions, i.e.

33、 wet/dry and presence of surface contamination. NOTE 3 Slip/ Skid resistance is not a constant but varies with climate and traffic and the effect of these on the characteristics of the surface material itself.

34、 two bodies in contact.

35、mine the Pendulum Test Value at a single location or for a single sample in the laboratory. In the field a number of tests will be required to determine the slip/skid resistance of an area 4 Safety When carrying out the test in the field, the equipment and operator will form a stationary obstruction

36、. Adequate safety measures shall be in place to maintain a safe working area in accordance with regulations. 5 Principle The Pendulum Tester incorporates a spring-loaded slider made of a standard rubber mounted to the end of a pendulum arm. Upon releasing the pendulum arm from a horizontal position,

37、 the loss of energy as the slider assembly passes over the test surface is measured by the reduction in length of the upswing using a calibrated scale. 6 Test equipment 6.1 The pendulum tester shall consist of the essential features given below and as illustrated in Figure 1.

41、specified in 6.3 (wide slider assembly) and 6.4 (narrow slider assembly). It shall be mounted on the end of a pendulum arm so that the sliding edge is (514 6) mm from the axis of rotation. 6.1.2 Means for setting the support column of the equipment vertical. NOTE The three leveling screws are normal

NOTE A mass of the frame of 3,5 kg has been found suitable. 6.1.4 Means of raising and lowering the axis of suspension of the pendulum arm so that the slider can: swing clear of the surface of the specimen, and be set to traverse a surface over a fixed length of (126 1) mm. A gauge with

44、 this distance marked is required as shown in Figure 2. NOTE The sliding length may be measured on the surface using tapered gauge 126. Alternatively, gauge 124 of thickness (8 0,2) mm may be used to set the sliding length, which has appropriate marks, aligning the marks with the aluminium backing a

The mass of the pointer shall be not more than 85 g. 6.1.7 The friction in the poi

47、nter mechanism shall be adjustable so that, with the pendulum arm swinging freely from a horizontal position, the outward tip of the pointer may be brought to rest on the forward swing of the arm at a point (10 1) mm below the horizontal. This is the 0 reading. 6.1.8 A circular scale (unit scale C)

48、as described in Table B.1, calibrated for a nominal sliding length of 126 mm on a flat surface marked from 0 to 150 at intervals of five. Tests in this mode of operation give the Pendulum Test Value directly. BS EN 13036-4:2011EN 13036-4:2011 (E) 9 6.1.9 A circular scale (unit scale F) as described

49、in Table B.2, calibrated for a nominal sliding length of 76 mm sliding length on a flat surface marked from 0 to 1 at intervals of 0,05 units, may also be present. This is used for a number of laboratory tests as described in the relevant Standards. The Pendulum Test Value may be estimated by calculation. NOTE In EN 10978-8, the narrow slider and the sliding length of (761) mm is used. 6.1.10 All bearings
