Gmax testing in Salem, Illinois

Surface Performance carry out Gmax, HIC & Clegg testing throughout the USA to ensure all artificial and natural surfaces are in line with ASTM standard F1936.

If a surface is too hard, according to ASTM F1936 (+200g’s), it would be deemed unsafe for use as it exerts excessive impact on the users. This excessive force would result increase risk of injury or concussion to an unacceptable level. The Gmax result reflects the impact attenuation of the surface and can therefore be used as an indicator as to whether the surface is fit for use.

Gmax testing is recommended to be carried out on an annual basis to ensure player safety is closely monitored. To find out more or schedule your test today, you can contact us using the form below and one of our team will be happy to assist.
