Shock Absorption: G-Max / HIC / Deformation
ASTM F1936 2015 Evaluation of Multiple Synthetic Turf Systems with Multiple thicknesses of foam used as an Elastic Layer. (G-MAX)
Summary:
A total of 3 turf samples were tested. One of the samples did not require any infill. The other two were an infill system. The foam thicknesses tested were nominally 3/8” and 5/8”. All testing was performed over a concrete slab by third party lab. The slab depth was nominally 6”. Equipment methods conforming to ASTM F1936 2015 were used. Full tests available upon request.
Testing Procedures:
Testing was conducted according to ASTM F1936 2015. The testing climate was 73.4°F, 45% relative humidity.
Test Results:
The table below contains the average performance values obtained on the evaluated sport surface system, as well as the requirements of EN 14904 2006.

Summary:
A total of 3 turf samples were tested with an infill system. The foam thicknesses tested were nominally 3/8” and 5/8”. All testing was performed over a concrete slab by third party lab. The slab depth was nominally 6”. Equipment methods conforming to ASTM F355-16e1 and ASTM F3189-17 were used. Full tests available upon request.
Testing Procedures:
Testing was conducted according to ASTM F355-16e1. The testing climate was 75°F, 42~45% relative humidity.
Testing was conducted according to ASTM F1989-17. The testing climate was 70°F, 42~43% relative humidity.
Test Results:
The table below contains the average performance values obtained on the evaluated sport surface system.
G-Max 2nd/3rd Impact Average | HIC | Deformation | |
---|---|---|---|
3/8" Grooved Foam | 92 | 215 | 10mm |
5/8" Grooved Foam | 72 | 149 | 12mm |
