EN 15301-1:2007 (E) 4 1 Scope This part of EN 15301 specifies methods for determining the rotational resistance of sports surfaces. 2 Normative References The following referenced documents are indispensable for the application of this
14、document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 12229, Surfaces for sports areas - Procedure for the preparation of synthetic turf and needle-punch test pieces 3 Principle The
15、 force required to initiate rotational movement of a test sole in contact with the sports surface being tested is measured. 4 Apparatus 4.1 The apparatus shall consist of the following components (see Figure 1). Test foot, comprised of a steel disc (150 2) mm in diameter to which the appropriate tes
16、t sole is mounted. Shaft with attached lifting handles that are centrally attached to the centre of the studded disc. Two-handled mechanical torque wrench with a scale marked from 0 Nm to 80 Nm in a maximum of 2 Nm increments, that attaches to the top of the shaft. Set of annular weights that rest c
17、entrally on the upper surface of the studded disc allowing free movement of the disc beneath the weights. The total mass of the apparatus (test foot, shaft, torque wrench and weights) shall be (46 2) kg. Tripod and guide to minimize any lateral movement of the test foot during testing. The tripod sh
18、all not restrict the free rotation of the shaft and the guide shall incorporate a means of holding and dropping the weighted test foot onto the test specimen from a height of (60 5) mm. 4.2 The test sole shall be as specified in the product specification. Standard test soles are as follows: a) Footb
19、all stud test sole; Six football studs1equally spaced on the bottom surface of the test foot (46 1) mm from the centre of the disc. The studs shall be as shown in Figure 2, be manufactured from plastic and have a Shore A hardness of (96 2). 113 mm nylon studs supplied by Decathlon Group are an examp
20、le of suitable products available commercially. This information is given for the convenience of users of this European Standard and does not constitute an endorsement by CEN of this product.

26、e measuring a minimum of 1 000 mm x 1 000 mm and prepared in accordance with the manufacturers instructions. Synthetic turf and needle-punch surfaces shall be prepared in accordance with EN 12229 and the manufacturers instructions. EN 15301-1:2007 (E) 9 6 Conditioning Condition the test pieces for a
27、 minimum of 3 h at the test temperature. Unless otherwise specified, the laboratory test temperature shall be (23 2) C. Site tests shall be made under the prevailing conditions. 7 Procedure Ensure that the test sole is cleared of any in-fill and detritus. Assemble the apparatus and ensure the free m
28、ovement of the test foot. For synthetic turf and needle punch surfaces remove the torque wrench and drop the weighted test foot from a height of (60 5) mm onto the surface. Reattach the torque wrench. For all other forms of surface place the apparatus onto the surface taking care not to damage the s
29、urface. Zero the indicator needle on the torque wrench. Without placing any excessive vertical pressure on the torque wrench and while applying minimum rotational torque to the torque wrench, turn the wrench and test foot smoothly, without snatching, at a nominal speed of rotation of 12 r/min until
30、movement of the test foot occurs and it has rotated through at least 45 . Record the maximum value displayed on the torque wrench to the nearest Nm. Move the test apparatus and repeat the procedure to obtain five results, unless otherwise specified, ensuring that the test positions are at least 50 m
31、m apart (outside edge of test foot to outside edge of test foot) and at least 50 mm from the sides of the test piece. If a conditioning procedure is used that produces a test piece of less than 1 000 mm x 1 000 mm, make a minimum of three measurements. 8 Calculation and expression of results Calcula
32、te the mean value of rotational resistance. Report the mean result to the nearest Nm, e.g. 40 Nm. 9 Test report The test report shall include the following information: reference to this European Standard, i.e. EN 15301-1:2007; complete identification of the surface tested, including its location, a
33、rea and previous history; test sole used; mean value of rotational resistance ; individual test results, if required.
