1.1 本规范规定了决定粒度、稠度、纯度和排水能力的因素的最低特性。 1.2 符合本规范要求的工程木纤维必须符合本规范的要求 F1292 ，如果表面位于规范中定义的使用区内 F1487 . 1.3 符合本规范要求的木纤维样品可指定为工程木纤维，适用于操场安全铺面。 1.4 本规范并不意味着如果工程木纤维符合本规范，则不会造成伤害。 1.5 为了满足本规范的要求，材料应具有以下性能: 1.5.1 材料应符合粒度要求。 1.5.2 材料应符合金属颗粒的要求。 1.5.3 材料应符合对儿童有害的允许重金属浓度。 1.5.4 材料应符合规范要求 F1292 . 1.6 以英寸-磅为单位的数值应视为标准值。括号中的值是数学转换。提供信息的国际单位制不被视为标准，除非 8.4 . 1.7 警告- 环保局和许多国家机构已将汞指定为一种有害物质，可导致中枢神经系统、肾脏和肝脏损害。汞或其蒸汽可能对健康有害，并对材料具有腐蚀性。处理汞和含汞产品时应小心。有关详细信息，请参阅适用的产品材料安全数据表（MSDS）和美国环保局网站（http: //www.epa。gov/mercury/faq。htm）以获取更多信息。用户应意识到，州法律可能禁止在您所在州销售汞或含汞产品，或同时销售两者。 1.8 以下预防说明仅适用于试验方法部分 7.4 , 8.4 和 9.4 本规范: 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。

1.1 This specification establishes minimum characteristics for those factors that determine particle size, consistency, purity, and ability to drain. 1.2 Engineered wood fiber that meets the requirements of this specification must comply with Specification F1292 , if the surface is in the use zone as defined in Specification F1487 . 1.3 A sample of wood fiber that meets the requirements of this specification may be designated engineered wood fiber and be suitable for playground safety surfacing. 1.4 This specification does not imply that an injury cannot be incurred if the engineered wood fiber complies with this specification. 1.5 To meet the requirements of this specification, the material shall perform as follows: 1.5.1 The material shall meet particle size requirements. 1.5.2 The material shall meet the requirement for metal particles. 1.5.3 The material shall meet the allowable heavy metal concentrations considered hazardous to children. 1.5.4 The material shall meet the requirements of Specification F1292 . 1.6 The values stated in inch-pound units are to be regarded as standard. The values in parentheses are mathematical conversions. SI units, which are provided for information, are not considered the standard, except in 8.4 . 1.7 Warning— Mercury has been designated by EPA and many state agencies as a hazardous material that can cause central nervous system, kidney, and liver damage. Mercury, or its vapor, may be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury-containing products. See the applicable product Material Safety Data Sheet (MSDS) for details and EPA’s website (http://www.epa.gov/mercury/faq.htm) for additional information. Users should be aware that selling mercury or mercury-containing products, or both, in your state may be prohibited by state law. 1.8 The following precautionary statement pertains to the test method portions only, in 7.4 , 8.4 , and 9.4 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. 1.9 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.
