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.

This specification covers all extractable hazardous metals (man-made or natural) that are intended for use as infill materials for synthetic turf sports surfaces. It specifies 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.

This specification includes requirements with respect to performance (hazardous metal content), test methods, sampling, apparatus, reagents, and procedure.

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.
