There is one principal source of tests for tennis court surfaces in Australia
The International Tennis Federation (ITF) is the world-wide governing body of tennis and has the following Guide to Test Methods for Tennis Court Surfaces
Acousto-Scan is accredited for One Star/Two Star ITF testing
One-Star ITF Recognition
To obtain One-Star ITF Recognition, the court is tested for quality of installation
.. Visual inspection. The court is inspected for visual flaws.
.. Evenness (ITF CS 02/02). Undulations in the surface of the court are measured.
.. Slope and planarity (ITF CS 03/03). The height of the surface is surveyed at a range of locations around the court
.. Dimensions (ITF CS 04/02). The positions of the lines and net are measured
All test results must meet the recommendations contained in the ITF Guide to Test Methods for Tennis Court Surfaces to be eligible for One-Star Recognition.
Testing for One-Star Recognition shall be conducted by an ITF Accredited laboratory or other company approved in advance by the ITF.
Recipients of One-Star Recognition shall receive a certificate from the ITF, confirming that the court/s tested meet the recommendations of the ITF Guide to Test Methods for Tennis Court Surfaces.
Two-Star ITF Recognition
To obtain Two-Star ITF Recognition, the average Court Pace Rating (CPR) of the court must be within 5 points of the ITF Classified value for the surface product(ITF CS 01/02) in addition to fulfilling the requirements for One-Star Recognition.
If the surface product is not already classified, the product supplier may apply for ITF Classification of the surface product based on the average results of all courts using the product tested on-site. The full ITF Classification fee will apply and classification will be valid for 3 years
Note: Two-Star ITF Recognition cannot be granted to courts where the surface product has not been classified under the ITF Court Pace Classification Programme. Recipients of Two-Star Recognition shall receive a certificate from the ITF, confirming that the court/s tested meet the recommendations of the ITF Guide to Test Methods for Tennis Court Surfaces.
