1.1 This test Method provides a consistent sampling apparatus and procedure for obtaining measurable infill samples of synthetic turf infill materials and calculating material volumes and application rates in the field. It includes a standard diameter apparatus which allows for uniform and thorough removal of infill materials over a constant area, and a battery powered scale of size suitable for measuring the weight of the obtained sample, while in the field. 1.2 Samples can also be dried in the laboratory in order to obtain a weight of the sample to determine dry material volumes and application rates. 1.3 Where infill samples are composed of more than one material they can be separated using a Gold Centrifuge Bowl and dried in the laboratory for determining application rates of material components. 1.4 Where on site infill material density is required average of the infill depth readings, the apparatus sampling surface area and weight should be used to calculate the average density of the sample at the sampling location.

Currently methods of infill sampling procedures differ from vendor to vendor and from technical agent to technical agent. Providing a uniform procedure for sampling will allow for more consistent evaluation in the laboratory of samples taken in the field. As the useful life of fields come to an en the need to evaluate the potential of reusing the infill material within the new field, disposing of the infill determining a new potential reuse solution is becoming more and more important. This should assist in this important part of end of field life.
