1.1This test method provides a consistent sampling procedure for obtaining infill samples of synthetic turf infill materials in the field.

1.2Operational considerations include:

1.2.1This method requires that attic stock infill materials or infill materials from areas that are out-of-play be available for refilling holes left by the sampling procedure. Replacement of infill materials shall match the composition of the material removed.

1.2.2Using this method to determine the in-situ weight and density will result in unreliable data due to the inclusion of moisture within the infill materials. Proper laboratory procedure including wet weight, dry weight before separation, and component weight after separation ensure no loss, and reliable data.

1.3Evaluation and analysis of the samples in the field and or laboratory are not covered herein.

1.4The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.5This 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.

1.6This 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.
