1.1 本规范规定了决定可访问性的因素的最低特征。本规范适用于所有类型的材料，这些材料可作为穿过游戏区、游乐场设备下方和周围的无障碍通道。 1.2 作为通过游戏区、游乐场设备下方和周围的可进入路线的材料也必须符合本规范 F1292 或试验方法 F3351 ，或两者兼而有之，如果表面在坠落区内。 1.3 符合本规范的表面系统不会防止使用表面时发生所有类型的伤害。 1.4 国际单位制功是焦耳（J），定义为一牛顿力通过一米位移所消耗的功。仅当尺寸等效牛顿计（N*m）后接术语“功”时，才应使用，以免混淆为扭矩值。（1牛顿*米=0.73756215磅力英尺）。 1.5 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；看见 IEEE/ASTM SI 10 了解更多详细信息。 1.6 以下预防说明仅适用于本规范的试验方法部分: 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。 1.7 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====== 7.1 本规范的目的是建立轮椅作业的定量测量，该测量与用作游乐场内部件的无障碍路线和净地面空间的表面材料或表面系统的坚固性和稳定性有关。 7.2 本规范提供了客观量化不同游乐场表面材料性能的统一方法。

1.1 This specification establishes minimum characteristics for those factors that determine accessibility. This specification applies to all types of materials that can be used as the accessible route through the play area, under and around playground equipment. 1.2 The material used as the accessible route through the play area, under and around playground equipment that meets this specification must also comply with Specification F1292 or Test Method F3351 , or both, if the surface is within the fall zone. 1.3 Surface systems in compliance with this specification will not prevent all types of injuries from occurring when the surface is used. 1.4 The SI unit of work is the joule (J), which is defined as the work expended by a force of one newton through a displacement of one meter. The dimensionally equivalent newton-meter (N*m) shall be used only if it is followed by the term “work” so it is not confused to be a torque value. (1 N*m = 0.73756215 pound-force-feet). 1.5 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; see IEEE/ASTM SI 10 for further details. 1.6 The following precautionary statement pertains only to the test method portions of this specification: 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 ====== 7.1 The purpose of this specification is to establish quantitative measurements for wheelchair work that are related to the firmness and stability of a surface material or surface system used as the accessible route and clear ground space at components within a playground. 7.2 The specification provides a uniform means of objectively quantifying the performance of different playground surfacing materials.
