GMAX Testing

Gmax test at University of Oregon

G-Max testing is the standard method developed for testing and determining the shock attenuation of synthetic turf athletic fields. Impact testing of synthetic turf is importantas G-Max values can directly correlate to the safety of the playing surface. Higher G-max values indicate harder playing surfaces, leading to higher probability of concussions and other injuries from impacting the surface. The ASTM has established a G-Max value of 200 as the maximum allowable limit, however ideal conditions should never exceed 165 at any location on the field.

At LDD Sports, we use state of the art G-Max testing equipment, to provide unmatched consistency and accuracy. All certified testing agents are trained to perform G-Max testsper ASTM standards. The data obtained is analyzed and documented by us as an independent agency. A report will be generated for each field indicating results, test methods,and will include all field data
