This publication is not to be regarded as a British Standard.It is being issued in the Draft for Development series of publications and
7、is of a provisional nature because there is a lack of experience in the use of this test and insufficient data are available to confirm its validity. It should be applied on this provisional basis, so that information and experience of its practical application may be obtained. Comments arising from

A review of this publication will be initiated 2 years after its publication by the European organization so that a decision

Notification of the start of the review period will be made in an announcement in the appropriate issue of UpdateStandards.According to the replies received by the end of the review period, the responsible BSI Committee will decide whether to
10、 support the conversion into a European standard, to extend the life of the Technical Specification or to withdraw it.

19、ecretariat of which is held by BSI. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to announce this CEN Technical Specification: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece,

CEN/TS 15122:200541 Scope This Technical Specification describes a method for the determination of the resistance of a sy
21、nthetic sports surface to repeated impacts. 2 Principle A test piece taken from a synthetic sports surface is submitted to a number of impacts from an impacter fitted with studs, after which the surface is examined for surface defects. 3 Apparatus Impact machine (see Figure 1) comprising a motor whi
22、ch drives, by means of a handle, a swinging arm, at the end of which is fitted an impacter (see Figure 2), fitted with three studs, arranged as shown in Figure 3. The studs shall have a length of (12,5 1,0) mm and a diameter of (12,7 1,0) mm and be made of hard plastics having a Shore A hardness of
23、at least 95 , e.g. polyamide. The movement of the swinging arm shall be controlled by a connecting rod, the length of which shall be adjusted so that the low point of the handle corresponds to the swinging arm being in the vertical position. The impacter shall be positioned so that it comes into con
24、tact with the test piece when this is placed on the rotating plate. A holder shall be provided to hold the test piece in position on the rotating plate. NOTE Movement of the impacter causes rotational movement of the test piece. Means shall be provided to count the number of strikes made by the impa
25、cter and the number of revolutions of the rotating plate. The impacter shall contain a spring which can be compressed by a screw to adjust the force exerted on the test piece (see Figure 2). Means shall be provided to measure the force applied to the test piece by the impacter. CEN/TS 15122:20055Dim

28、ioning Condition the test pieces for 24 h at a temperature of (23 2) C and a relative humidity of (50 5) %. 6 Procedure Measure the thickness of one of the test pieces. Attach the test piece to the test piece holder, e.g. by using double-sided adhesive tape. Weigh the test piece together with the te
29、st piece holder. Place the test piece holder on the rotating plate. Adjust the impacter so that it exerts a force of (711 10) N on the test piece. Start the impact machine and adjust it so that the impacter strikes the test piece (6 000 100) times per hour. Run the machine until the test piece has b
30、een impacted 40 000 times, stopping it periodically, e.g. approximately every 6 000 impacts, to inspect the test piece for visible cracks. If visible cracks appear, terminate the test. Record the number of impacts up to the point where the cracks appeared, if appropriate. If no cracks appeared, reco
31、rd the figure 40 000. Re-weigh the test piece together with the test piece holder. Remove the test piece from the holder and re-measure its thickness. Calculate any loss in mass and any reduction in thickness. Repeat the procedure using the remaining two test pieces. CEN/TS 15122:200587 Test report
32、The test report shall include at least the following information. a) reference to this document, i.e. CEN/TS 15122:2005; b) description and identification of the material tested; c) visual appearance of each test piece before and after the test; d) for each test piece, any reduction in thickness; e)
33、 for each test piece, any loss of mass; f) for each test piece, the number of impacts made.
