Gmax testing has recently become universally recognised as a vital test in respect to player safety on artificial turf. Surface Performance offer gmax testing in Oraibi, Arizona to ensure all pitches are meeting the ASTM standards.

Gmax and HIC (Head Impact Criterion) testing focus on the impact absorbed by an athlete upon impact with the playing field. Using a weight and an accelerometer, our specialist equipment will measure the impact absorbed by the surface and therefore the remaining force left for the user to absorb. If this remaining force is too great the risk of injury/concussion would be deemed too high.
