Ball rebound

Determination of the vertical ball rebound to assess the bounce characteristics of a playing surface when a ball is released from a magnet at a specified height and dropped onto the surface.

Ball roll

Ball roll is determined by measuring the distance a ball covers when rolling on the surface after it is being released from a specific height and through a ramp of predefined specifications. This test assesses the extent of the ball's unimpeded movement across the pitch.

Surface planarity

Determination of evenness by locating deviations of the surface under a 3 m straight edge.
The method is used to assess surface regularity and, most importantly, to map out all pitch areas of potential risk to players.

Rotational resistance

Determination of the surface resistance to rotation exerted by a studded test plate simulating a player’s foot.
This test method assesses the stability of a sports turf surface.

Surface hardness

Measurement of surface hardness under the impact of the player's foot.

Soil moisture

Surface moisture, determined as the volumetric water content in topsoil, with the Time Domain Reflectometry (TDR) method.

Infiltration rate

This test measures water penetration rate into the tested surface.
The method determines the ability of the turf to absorb water and carry it to the drainage system.

Compaction severity

This test method determines the level of compression at specific depths.
Soil compaction affects the physical properties of the playing surface, as well as root development.

Root depth

Determination of root system growth by measuring root depth in samples from specific site locations.

Infill depth

The test measures the depth of the infill material layer across the playing surface.

Rotational resistance

Determination of the surface resistance to rotation exerted by a studded test plate, a simulation of a player’s foot.
Traction is a crucial aspect of the interaction between player and surface that can significantly affect players’ performance and pose injury risks.

Free pile height

This test method is used to measure the non-elongated free pile height in artificial turf carpets, or the sward length of turfgrass in natural and hybrid system surfaces.

Surface planarity

Determination of evenness by locating deviations of the surface under a 3 m straight edge.
The method is used to assess surface regularity and, most importantly, to map out all pitch areas of potential risk to players.
