1.1 该试验方法测量表面系统和材料的冲击衰减，特别是峰值冲击加速度（“冲击冲击”），并计算在规定冲击条件下产生的头部损伤标准。 1.2 本试验方法适用于由天然材料或合成材料制成的旨在提供冲击衰减的表面系统。 1.3 本试验方法适用于体育设施中使用的冲击衰减垫和衬垫，包括但不限于:体育场墙壁衬垫、体操垫、摔跤垫、草皮运动系统、撑杆跳着陆系统和操场保护表面。 1.4 本试验方法用于测量用作蹦床框架、门柱等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附设备分开进行试验。 1.5 除非对整个系统的冲击衰减感兴趣，否则，在不进行修改的情况下，不得使用此测试方法来测试附着在结构、设备或成品上的材料和组件。 1.6 虽然人们普遍认为，较低的冲击衰减值可以降低与冲击相关的伤害的严重程度，但这种测试方法的结果与特定伤害风险之间的关系在汽车测试数据中。 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 本标准并不旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.9 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 该方法的结果量化了在特定测试条件下，无论是在实验室内还是在表面系统安装使用的位置，游戏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。它没有量化测试样品的固有材料特性。 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）获得的不同试样的试验结果。 )用于比较在这些条件下的冲击衰减。 5.4 在不同条件下获得的试验结果不具有可比性。用不同的导弹获得的具体结果是不等价的，不能直接比较。同样，使用相同的导弹，但使用不同的跌落高度获得的测试结果也不能直接比较。

1.1 This test method measures the impact attenuation of surface systems and materials, specifically the peak impact acceleration (“impact shock”) and calculates the Head Injury Criteria produced under prescribed impact conditions. 1.2 This test method is applicable to surface systems intended to provide impact attenuation, made of naturally occurring or synthetic materials. 1.3 This test method is applicable to impact attenuating mats and padding used in sports facilities, including, but not limited to: stadium wall padding, gymnastic mats, wrestling mats, turf playing systems, pole vault landing systems, and playground protective surfacing. 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 lower values for impact attenuation can reduce the severity of impact-related injuries, the relationships between the results of this test method and specific injury risk are within automotive testing data. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.9 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 results of this method quantify the impact attenuation of playing surface and system specimens under the specific test conditions, either within a laboratory or the location the surface system is installed for use. 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.
