1.1 本规范涉及某些金属的含量，这些金属在摄入时可能从人造草坪填充材料中提取。提取液的时间、温度和pH值与胃内填充物在消化过程中所经历的条件近似。将可提取金属的含量与儿童玩具中允许的最高含量进行比较。 1.2 本规范适用于拟用作人造草坪运动表面填充材料的所有材料（人造或天然）。 1.3 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.4 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。 1.5 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 本试验方法基于消费者安全规范第8.3小节 F963 它规定了一个测试程序，以确定玩具中可能存在的、儿童处理或摄入的有害金属的数量。由于人造草坪运动表面的用户可以处理或摄入人造草坪填充材料的颗粒，因此有必要确定人造草坪填充材料中有害金属的含量。本规范中使用的危险金属限值基于《消费者安全规范》中规定的限值 F963 ，根据消费者安全规范中所述的统计误差修正系数进行调整 F963 .

1.1 This specification relates to the amount of certain metals that have the potential to be extracted from synthetic turf infill materials if ingested. The time, temperature, and pH of the extraction fluid approximate the conditions the infill material would experience in the stomach during the digestive process. The levels of extractable metals are compared to maximum levels allowed in children’s toys. 1.2 This specification applies to all materials (man-made or natural) that are intended for use as infill materials for synthetic turf sports surfaces. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.4 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. 1.5 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 This test method is based on subsection 8.3 of Consumer Safety Specification F963 , which specifies a test procedure to determine the amount of hazardous metals that have the potential to be present in toys and handled or ingested by children. Since it is possible for users of synthetic turf playing surfaces to handle or ingest particles of synthetic turf infill materials, it is necessary to determine the level of hazardous metals in the synthetic turf infill materials. The limits of hazardous metals used in this specification are based on those specified in Consumer Safety Specification F963 , adjusted for statistical error correction factor as described in Consumer Safety Specification F963 .
