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” , 1/2”, 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.

 

System 1:A field hockey type turf with a nominal pile height of 1/2”. No infill was used for this system.
G-Max 2nd/3rd Impact Average
3/8” Foam135
1/2” Foam114
5/8” Foam                   105

  

System 2:An infilled system with pile length of nominally 1.75”. Infill/sand was provided by Armacell. Infill was placed to a nominal depth of 1.25”, leaving approximately 0.5” of the piles exposed.
G-Max 2nd/3rd Impact Average
3/8” Foam95
1/2” Foam84
5/8” Foam                   70

ASTM F3189-17: Standard Test Method for Measuring Force Reduction, Vertical Deformation, and Energy Restitution of Synthetic Turf Systems Using the Advanced Artificial Athlete (Deformation)

Summary:

A total of 3 turf samples were tested with an infill system. The foam thicknesses tested were nominally 3/8” , 1/2”, 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.

 

System 2 (Grooved Foam):An infilled system with pile length of nominally 1.75”. Infill/sand was provided by Armacell. Infill was placed to a nominal depth of 1.25”, leaving approximately 0.5” of the piles exposed.
