Gmax testing in Selma, Alibama to American Society for Testing and Material (ASTM) Standards

Surface Performance Ltd are market leaders in the testing and certification of artificial and natural sport surfaces. We offer Gmax, HIC and Clegg testing in Selma, Alabama.

Gmax testing uses a 20lb, cylindrical weight, dropped from 24inches to measure how many G’s of force a surface can absorb upon impact and how many are therefore returned to the athlete. Surface Performance Ltd accredited engineers carry out Gmax testing to ASTM Standard F355-A which state that any field with a Gmax rating over over 200G’s is deemed unsafe for use. Ultimately, the higher the Gmax result, the higher the impact and therefore increased likelihood of injury to the user of the surface.

Gmax testing is designed to replicate the impact of a players torso. Surface Performance Ltd utilise the HIC test which is the internationally recognised test for head injuries.

Many factors contribute to the Gmax rating on a playing surface all of which can quickly change, impacting the safety of the surface. Gmax testing is therefore recommended yearly to ensure the surface and player safety is monitored, and to highlight whether maintenance is required.
