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

1.2 Operational considerations include:

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

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

1.5 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.

1.6 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.

5.1 Currently methods of infill sampling procedures differ from vendor to vendor and from technical agent to technical agent. Providing a uniform procedure for sampling, which allows for a consistent vertical sample, will allow for more consistent and accurate evaluation/measurement in the laboratory of samples taken in the field.

5.2 The Sampling Program and associated Sample Area Site Plan (Map) shall take into account the specific purpose or purposes of the testing and determine appropriate sample areas based on needs and field conditions. A partial list of possible purposes include:

5.3 Laboratory testing that may be performed on obtained samples include but are not limited to:
