20、ound are assessed. 4 Apparatus 4.1Ball projector, providing a means of projecting a ball at a specified angle and velocity onto the surface without imparting spin greater than 3 rev/s. NOTE Suitable ball projection machines are available commercially. The release characteristics of the ball from the
21、 machine should be checked specifically (e.g. by stroboscopic photography) to ensure that spin in excess of 3 rev/s does not occur. 4.2Ball track monitor, providing a means of monitoring the track of the ball before and after impact such that its velocity can be measured to an accuracy of 0,01 m/s a
22、nd its angle of impact and rebound to 0,1. The uncertainty in the precision of the measuring technique shall be no greater than 2 %. NOTE The track of the ball can be monitored photographically or by timing its passage between light-sensitive receivers. In the latter case, the angle can be deduced f
23、rom the vertical and horizontal components of velocity. 4.3Pressurized tennis balls 4.3.1Balls in accordance with 4.3.2 are used in tests to demonstrate the conformity of a sports surface to a specification for the surface. Balls in accordance with 4.3.3 are used to demonstrate the performance of a
24、particular type of ball on a given surface, e.g. a particular brand of ball to be used in a tournament. 4.3.2At least three test tennis balls, taken from a pressurized ball canister, each covered with cloth weft comprising (33 6) % denier (6,67 dtex) polyamide and (67 3) % wool, and which, when test
