1.1 本指南涵盖了与公共滑板公园设施和其中包含的任何元素有关的安全和性能指南。这些指南适用于在运动表演中使用的任何元素，包括滑板、直排滑冰和BMX自行车。围栏、照明和操作结构等项目不属于本指南的一部分。 1.2 本指南适用于用于娱乐用途的地上（室内/室外）滑板公园元素。 1.3 本标准的文本引用了提供解释性材料的注释和脚注。这些注释和脚注（不包括表格和图表中的注释和脚注）不应被视为本标准的要求。 1.4 公差——一般测量、公差和转换-- 本规范的一般尺寸公差（除非另有说明）如下: 尺寸 宽容 X英寸或英尺 ±0.5英寸或英尺 X.X英寸或英尺 ±0.05英寸或英尺 X.XX英寸或英尺 ±0.005英寸或英尺 注1: 即使使用了大于、小于、最小或最大等术语，这些公差仍然适用于尺寸。 1.5 以英寸-磅单位表示的值应被视为标准值。括号中给出的值是对国际单位制的数学转换，仅供参考，不被视为标准值。 注2: 从英寸磅到国际单位制的转换系数为1英寸=25.4毫米，1磅=0。 45359公斤。 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。

1.1 This guide covers safety and performance guidelines pertaining to public skatepark facilities and any element included therein. These guidelines pertain to any elements intended to be used in the performance of the sports including skateboarding, inline skating, and BMX biking. Items such as fencing, lighting, and operational structures are not intended to be a part of this guide. 1.2 This guide applies to above-ground (indoor/outdoor) skatepark elements, intended for recreational use. 1.3 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. 1.4 Tolerances – General Measures, Tolerances, and Conversions— The general dimensional tolerances for this specification (unless otherwise noted) are as follows: Dimension Tolerance X in. or ft ±0.5 in. or ft X.X in. or ft ±0.05 in. or ft X.XX in. or ft ±0.005 in. or ft Note 1: These tolerances still apply to a dimension even when terms like greater than, less than, minimum, or maximum are used. 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. Note 2: The conversion factor from inch-pound to SI units is 1 in. = 25.4 mm, and 1 lb = 0.45359 kg. 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.
