16、is European Standard specifies a method for determining the rebound height of a ball from a surface, when dropped vertically. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated referenc

17、es, 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 A ball is allowed to fall vertica

18、lly onto a surface and the height to which it rebounds is measured and calculated as the percentage rebound height. 4 Apparatus 4.1 Ball, conforming to the regulations of the governing body of the relevant sport and with any additional requirements given in Table 1. NOTE These requirements have been

19、 found to be acceptable in use, and it has not been found necessary to specify additional requirements such as circumference or mass of the ball.

21、mpirically determined correction factor. bThe precision of the test using footballs is 10 % absolute. cThe rebound height from concrete is measured as described in 7.1 to determine if the ball is suitable for tests on the test piece. dThe drop height and rebound height should always be measured from

22、 the bottom of the ball. BS EN 12235:2013EN 12235:2013 (E) 5 4.2 Ball release device, which operates smoothly without imparting any impulse or spin to the ball and which allows the ball to be dropped vertically from the specified height. NOTE Examples of suitable devices include vacuum and mechanica

23、l arrangements or an electromagnetic release device with a very small thin metal plate attached to the test ball. 4.3 Acoustic recording apparatus, comprising a microphone and timing device, activated acoustically, and giving a reading accurate to within 1 ms. NOTE The device is activated by the sou

24、nd from the first bounce of the ball and deactivated by the sound from the second bounce, the time between these events being denoted T, in seconds. 5 Sports surface for testing The test may be carried out on site, on indoor or outdoor sports surfaces, or on a test piece assembled for test purposes.

25、 If a test piece is to be used, prepare this from a representative sample of the sports surface, in combination with the supporting layers used with the surface in service. Assemble the surface and supporting layers in accordance with the method recommended by the manufacturer so that the test piece

26、 is of minimum size 1,0 m x 1,0 m or larger on the manufacturers recommendation. Test pieces shall be prepared in accordance with EN 12229. NOTE 1 For certain constructions, such as unbound bases and area-elastic floors, a larger specimen might be necessary to be representative. For certain construc

27、tions, such as area-elastic and combined elastic floors, no mass (including test operatives) greater than 10 kg should be within a 1 m radius of the test location. NOTE 2 Smaller samples can be tested when the surface flooring has undergone special conditioning such as ageing on the Lisport and a 1,

28、0 m x 1,0 m sample size is not possible. 6 Conditioning Condition the test pieces for a minimum of 3 h at the test temperature, except when the material is known to be very sensitive to humidity, in which case condition them for a minimum of 88 h at a relative humidity of (50 5) % at the test temper

29、ature. Unless otherwise specified, condition and test the test pieces at a temperature of (23 2) C. For tests on site, condition the ball for a minimum of 1 h at the prevailing temperature and humidity. 7 Procedure 7.1 Determination of the rebound height of the ball from concrete Set the ball releas

30、e device at the appropriate drop height for the ball, as given in Table 1. Drop the ball onto a stable concrete test surface of minimum size 1,0 m x 1,0 m or larger and minimum thickness 0,05 m, ensuring that the ball does not hit the surface within 100 mm of the edge of the surface. If a concrete t

31、est surface is not available, an appropriate floor with a rigid substrate may be used. A suspended floor structure is not suitable. Record from the timing device the time, T, in seconds, between the first and second bounces of the ball. Calculate the height, H, in metres to which the ball rebounds u

32、sing the following formula: BS EN 12235:2013EN 12235:2013 (E) 6 ( )2123,1 KTH = where T is the time in seconds, between the first and the second bounces of the ball; K1is the correction factor, in seconds, given in Table 1. Repeat the procedure to obtain a total of five readings all within a 1,0 m r

33、adius. Calculate and record the mean of the five values of H as the rebound height of the ball from concrete. If the rebound height differs from the value given in Table 1, either discard the ball and repeat the procedure using another ball(s) until the value is met, or, if applicable, adjust the ba

34、ll inflation pressure and repeat the procedure until the value is met. 7.2 Determination of the rebound height of the sports surface For tests in the laboratory, repeat the procedure given in 7.1, overlying the concrete test surface with the sports surface. For tests on site, repeat the procedure gi

35、ven in 7.1 replacing the concrete test surface with the sports surface. For tests under wet conditions, prepare the test area using the procedure specified in the relevant product specification. When making measurements on site, record the temperature and whether the surface was dry or wet. 8 Expres

36、sion of results Calculate the relative percentage rebound height, for the sports surface from the following formula: 100% =CSRRR where R% is the relative percentage rebound height; RSis the rebound height from the sports surface, in metres; RCis the rebound height from concrete, in metres. 9 Test re

37、port The test report shall include the following information: a) reference to this European Standard, i.e. EN 12235:2013; b) complete description of the surface tested, including the manufacturers reference, type of supporting layers and method of attachment; c) conditions under which the test was c

38、arried out, i.e. either under laboratory conditions with details of conditioning, or on site, in ambient conditions; d) the temperature and moisture condition at which the test was carried out, if applicable; BS EN 12235:2013EN 12235:2013 (E) 7 e) description of the type of the ball used in the test

39、 and the height from which it was dropped; f) relative percentage rebound height; g) absolute rebound height; h) date of the test.
