ASTM F1936 Test Report
This test is performed in accordance with ASTM F1936-10, a Standard Specification for Shock-Absorbing
Properties of North American Football Field Playing Systems as Measured in the Field. The results
reported herein reflect the performance of the tested playing field surface at the time of testing and the
temperature and ambient conditions reported. Performance will vary with the temperature, moisture
content and other factors.
The test is performed using a Clegg Impact Tester manufactured by Turf Tec International, in
conformance with the technical requirements of ASTM F355 procedure A.

The drop height each test location is 2’ and the velocity at the point of impact shall be 11.35 ±0.56 ft/s. The drop
height is physically measured. The drops are performed from the same drop height to the same point on the
surface.
The ASTM F1936 requires that the average Gmax of the second and third drops at a single test point shall not
exceed 200 average Gmax. If a turf system is tested in accordance with the Test Method ASTM F355, Procedure C,
as specified, and the average Gmax of 1 or more of the tested points reported is in excess of 200 average Gmax,
the surface system should be replaced in full or in part.
