1.1 本试验方法测量表面系统和材料的冲击衰减，特别是在规定冲击条件下产生的峰值冲击加速度（“冲击冲击”）。 1.2 本试验方法适用于旨在提供冲击衰减的天然和人造表面系统，包括天然和人造草坪运动场。 1.3 本试验方法适用于体育设施中使用的减震垫和衬垫，包括体育场墙壁衬垫、体操垫、摔跤垫、草皮运动系统、撑杆跳着陆系统、操场保护性铺面和其他系统。 1.4 本试验方法用于测量蹦床框架、球门柱等上用作保护垫的材料和部件的冲击衰减，前提是该材料或部件可以与所连接的设备分开进行试验。 1.5 未经修改，本试验方法不得用于测试附着在结构或设备或成品上的材料和组件，除非对整个系统的冲击衰减感兴趣。 1.6 虽然人们普遍认为适当的撞击衰减可以降低撞击风险- 尚未确定该测试方法的结果与特定伤害风险和结果之间的关系。 1.7 以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.8 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 5.1 该方法的结果量化了特定测试条件下播放表面和系统样本的冲击衰减。 5.2 该测试方法测量在特定条件下进行的冲击的结果。它没有量化测试样本的固有材料特性。 5.3 在相同条件下（即相同的导弹质量和几何形状、跌落高度等）获得的不同样本的测试结果用于比较这些条件下的冲击衰减。 5.4 在不同条件下获得的测试结果不具有可比性。用不同的导弹具体获得的结果并不等同，不能直接进行比较。同样，使用同一枚导弹，但使用不同落差的测试结果也不具有直接可比性。

1.1 This test method measures the impact attenuation of surface systems and materials, specifically the peak impact acceleration (“impact shock”) produced under prescribed impact conditions. 1.2 This test method is applicable to natural and artificial surface systems intended to provide impact attenuation, including natural and artificial turf sports fields. 1.3 This test method is applicable to impact attenuating mats and padding used in sports facilities, including stadium wall padding, gymnastic mats, wrestling mats, turf playing systems, pole vault landing systems, playground protective surfacing, and other systems. 1.4 This test method is used to measure the impact attenuation of materials and components used as protective padding on trampoline frames, goal posts, etc., provided the material or component can be tested separately from the equipment to which it is attached. 1.5 Without modifications, this test method shall not be used to test materials and components that are attached to structures or equipment or finished products, unless the impact attenuation of the whole system is of interest. 1.6 While it is widely believed that appropriate impact attenuation can reduce the risk of impact-related injuries, the relationships between the results of this test method and specific injury risk and outcomes have not been determined. 1.7 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.8 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== 5.1 The results of this method quantify the impact attenuation of playing surface and system specimens under the specific test conditions. 5.2 The test method measures the outcome of impacts performed under specific conditions. It does not quantify the intrinsic material properties of the tested specimens. 5.3 Test results from different specimens obtained under the same conditions (that is, the same missile mass and geometry, drop height, etc.) are used to compare impact attenuation under those conditions. 5.4 Test results obtained under different conditions are not comparable. Specifically obtained with different missiles are not equivalent and cannot be directly compared. Similarly, test results obtained using the same missile, but using different drop heights, are not directly comparable.
