SCOPE OF SERVICES Athletic Surface Inspection includes but is not limited to the assessment and inspection of new and existing natural grass turf , all weather turf ( synthetic ), basketball courts ( indoor / outdoor ), volleyball courts ( indoor / outdoor ), racquetball courts ( indoor / outdoor ), tennis courts , running tracks , playground surfacing and golf greens . Surfaces include , but are not limited to , acrylic color coatings , polyurethane coatings , synthetic and natural clay surfaces . Testing of athletic surfaces will include but is not limited to : - GMAX ( ASTM F1936 and F355A ) – Gives an indication of high impact shock absorption . - Shock Absorption and Vertical Deformation : Measures the impact absorption provided by synthetic turf to a player running ( lower extremity impact ) or falling on as well as the foot stability of the surface as a player runs across it . Excess deformation of a surface could lead to over strained joints and fatigue . - Rotational Resistance ( Traction ): Measures the interaction between the shoe sole and the surface of artificial grass relating to the ability of a player to change direction . - Slip Resistance Scale and Deceleration : Measures the ability of studs to slide through the surface without causing the player to slip over . Slip resistance deceleration measures the deceleration experienced by the players shoe as it makes contact with the surface . If the deceleration is too high , damages to joints and ligaments may occur . - Vertical Ball Rebound : Measures how high the ball bounces when falling vertically onto a synthetic turf field . ( Although a method for soccer , this also gives an indication of consistent infill levels throughout the playing surface in a low - cost tool ). - Ball Roll : Measures how far the ball rolls onto synthetic grass compared to natural grass . ( Although a method for soccer , this also gives an indication whether or not grass piles are standing up in a low - cost tool ).
