Test Explanation - Ball Type : BAT--9-a Height of bound - Client: Lawn Tennis Association of Thailand All balls had a bound within the specified limits ( cm - cm). Test items: Top One Size - (Thailand) Specification: International Tennis Federation Rules of Tennis - 0 Mass - Rule, Ball Type. All balls had a diameter within the specified limits (. cm -. cm). All balls had a mass within the specified limits (.0 g - 9. g). Test date: August 0 Forward deformation - Introduction This report summarises the results of testing that was carried out on the above items according to the International Tennis Federation Rules of Tennis. All balls had a forward deformation within the specified limits (0. cm - 0. cm), with a variation of no greater than 0.0 cm between the axes. Return deformation - All balls had a return deformation within the specified limits (0.0 cm -.0 cm), with a variation no greater than 0.0 cm between the axes. In order to pass an individual test, every result of each ball must be within the specified limits. For the ball to gain an overall pass, each test must be passed. Results valid from August 0 to December 0. Internal pressure (pressureless balls only) - Durability - All balls had durability characteristics within the specified limits. n/a Overall result - Form: ITF-M-00 rev., July 00 of Ball Pressurised
