1.1 本试验方法提供了一种使用模拟儿童头部与操场表面碰撞的试验方法来确定操场冲击衰减性能的方法。 1.2 本试验方法适用于与游乐场设备一起使用的铺面材料，如规范中所述 F1148 , F1487 , F1918 、CSA Z614（加拿大）和SS457（新加坡）。 1.3 本试验方法建立了确定在现场测试的操场表面冲击衰减值的程序，并与规范中在实验室条件下进行的测试进行比较 F1292 以及合同和保修要求。本试验方法未确定已安装操场表面的临界坠落高度。 1.4 本测试方法要求的现场测试涉及儿童玩耍期间在现场发现的操场表面的性能2- 预计为12。 1.5 冲击衰减试验方法和本试验方法中确定的试验方法针对头部受伤风险。有证据表明，降低冲击衰减值可以降低其他类型严重损伤（例如长骨骨折）的风险。 1.6 本试验方法仅涉及操场铺面材料的冲击衰减特性，不涉及导致坠落伤害的其他因素。虽然人们相信，符合本试验方法的要求将降低因跌倒而造成严重伤害和死亡的风险，但遵守本试验方法并不能防止所有伤害和死亡。 1.7 以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 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、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（TBT）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》中确立的国际公认标准化原则制定的。 ====意义和用途====== 6.1 本试验方法的目的是在试验时确定已安装操场表面的冲击衰减。 6.2 本试验方法提供了一种统一的方法，用于量化已安装游乐场表面的冲击衰减性能。 6.3 本试验方法将用作规定已安装游乐场表面冲击衰减性能的参考。 6.4 本试验方法提供了一种统一的方法，将已安装操场表面的冲击衰减性能与本试验方法的性能要求以及以跌落高度表示的其他性能要求进行比较。因此，本试验方法适用于确定在使用环境条件下安装的操场表面的实际冲击衰减性能。 6.5 结合冲击测试分数与头部受伤相关的数据，应用该测试方法生成的信息适用于估计因摔倒而导致严重头部受伤的相对风险。 6.6 本试验的性能不符合证明表面符合规范的要求 F1292 .

1.1 This test method provides a means of determining impact attenuation performance of a playground using a test method that simulates the impact of a child's head with the playground surfaces. 1.2 This test method is specific to surfacing materials used in conjunction with playground equipment, such as that described in Specifications F1148 , F1487 , F1918 , CSA Z614 (Canada), and SS457 (Singapore). 1.3 This test method establishes procedures for determining the impact attenuation value of playground surfaces as tested in the field and for comparison with the test performed under laboratory conditions in Specification F1292 and contract and warranty requirements. This test method does not establish the critical fall height for an installed playground surface. 1.4 The field test required by this test method addresses the performance of playground surfaces as they are found in the field during a time when play by children 2-12 is anticipated. 1.5 The impact attenuation test method and test methods established in this test method are specific to the risk of head injury. There is evidence that lowering impact attenuation values can reduce the risk of other kinds of serious injury (for example, long bone fractures). 1.6 This test method relates only to the impact attenuation properties of playground surfacing materials and does not address other factors that contribute to fall-related injuries. While it is believed that conformance with the requirements of this test method will reduce the risk of severe injury and death from falls, adherence to this test method will not prevent all injuries and deaths. 1.7 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 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 ====== 6.1 The purpose of this test method is to establish impact attenuation for the installed playground surface at the time of testing. 6.2 This test method provides a uniform means of quantifying the impact attenuation performance of installed playground surfaces. 6.3 This test method is to be used as a reference for specifying the impact attenuation performance of an installed playground surface. 6.4 This test method provides a uniform means of comparing the impact attenuation performance of installed playground surfaces with the performance requirements of this test method and with other performance requirements expressed in terms of drop height. Consequently, the test method is appropriately used to determine the actual impact attenuation performance of installed playground surfaces under ambient conditions of use. 6.5 In combination with data relating impact test scores to head injury, the information generated by application of this test method is suitable to estimate the relative risk of a severe head injury due to a fall. 6.6 Performance of this test does not satisfy the requirements to certify surfaces to the specification Specification F1292 .
