1.1 该测试方法涵盖了运动球和运动表面碰撞过程中产生的垂直回弹的定量测量和归一化。 1.2 可以在非运动表面上进行测量，以测试球的性能。 1.3 可以使用非运动球进行测量，以测试表面的性能特性。 1.4 所述方法适用于实验室和现场环境。 1.5 以公制单位表示的值应被视为标准。括号内的英寸-磅单位仅供参考。 1.6 本标准并不旨在解决与其使用相关的所有安全问题（如果有的话）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践，并确定监管限制的适用性。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。 =====意义和用途====== 5.1 球表面相互作用只是运动表面的重要特性之一。这可能是表面可玩性或适用性的指标。 5.2 运动球制造商可以使用这种方法来评估设计变更对回弹高度的影响。 5.3 运动场地制造商可以使用这种方法来评估运动场地系统设计变更对回弹高度的影响。 5.4 现代设施在单个表面上支持多种运动的趋势可能需要对几种类型的运动球进行测试。 示例包括但不限于:篮球、足球、网球和棒球。 5.5 如果球的温度没有与环境达到平衡，回弹高度的测量可能会受到影响。

1.1 This test method covers the quantitative measurement and normalization of the vertical rebound produced during impacts between athletic balls and athletic surfaces. 1.2 Measurements may be conducted on nonathletic surfaces to test the performance properties of the ball. 1.3 Measurements may be conducted using nonathletic balls to test the performance properties of the surface. 1.4 The methods described are applicable in both laboratory and field settings. 1.5 The values stated in metric units are to be regarded as the standard. The inch-pound units given in parentheses are for reference only. 1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 The ball-surface interaction is just one of the important properties of a sports surface. It may be an indicator of the playability or suitability of the surface. 5.2 Manufacturers of sporting balls may use this method to evaluate the effects of design changes on the rebound height produced. 5.3 Manufacturers of sports surfaces may use this method to evaluate the effects of design changes in the sports surface system on the rebound height produced. 5.4 The tendency of modern facilities to support multiple sports on a single surface may require that test surfaces be tested for several types of sporting balls. Examples include, but are not limited to: basketball, soccer, tennis, and baseball. 5.5 The measurement of rebound height may be affected if the temperature of the ball has not reached equilibrium with the environment.
