Ball Rolling Test: Measures actual playability

The interaction between the ball and the sports surface is essential for the correct playability of football pitches. A standard and uniform behaviour of the entire playing surface must be ensured.

Thus, it is possible to assess the ball rolling through the following test:

1. Purpose and field of applicationDetermination of the rolling of the ball in sports surfaces.
2. Principle of the methodMeasurement of the distance an inflated balloon rolls at a pressure of 0.7 bar after falling down an inclined plane at 45 degrees and a height of 1 metre at its highest point.
3. Description of equipmentInclined plane formed by two parallel guides, with a height of 1 metre and forming an angle of 45 degrees to the horizontal. Balloon inflated to 0.7 bar pressure. 15 metre tape measure.
4. Operating procedureThe inclined plane is placed in the area to be studied, in a random location and direction. The ball is held by hand at the top of the ramp and then released, allowing it to fall along the guides that form the inclined plane. Once the ball has stopped, the distance reached by the ball is recorded by measuring from the base of the ramp to the centre point of the ball. Five readings are taken at randomly selected points in each of the goal, flank and centre zones. At each chosen point the rolling distance in opposite directions is determined.
5. Calculation and expression of resultsThe results are expressed in metres. The average is calculated for each area.
6. Report testUNE 41959-1-2002 IN; Identification of the surface, location, area and previous history; Average rolling value per area; Individual results if required; Details of any deviations from the procedure.

With the rolling ramp and boat you can test your own course. Here you can buy yours.
