Gmax testing, or impact attenuation, measures the shock absorbed by the synthetic turf when impacted by a players torso or head. Surface Performance carry out Gmax testing to ASTM Standard F355-A.

Gmax testing is now an imperative test for those responsible for maintaining a safe pitch for their athletes. If the impact attenuation is too low, there can be an unacceptable risk of injury to players if excessive force is returned to the player.

Due to the numerous factors that can influence the properties of a playing field, it is recommended that the Gmax test be carried out twice per year. Contact us using the form below if you would like to find out more or book your Gmax test in Gary, Indiana today.
