ITF Test Court Pace Rating

ITF Court Pace Rating defines the ball-surface interaction effect called “Friction”.

Friction is mainly determined by the reduction of the horizontal component of the post-impact ball speed and by the vertical restitution, which in turn determines the time between subsequent bounces.

ITF Court Pace Classification Programme

The ITF Court Pace Rating Programme has been developed to help tennis court buyers select the surface best suited to their needs.
Surfaces can be classified into the following five categories; slow, medium-slow, medium, medium-fast and fast. End users can select a surface based on its playing speed.

Court Pace is established by shooting a ball onto the surface and recording its velocity before and after the bounce. Rough surfaces – which generate more friction between the ball and the court – reduce the ball’s horizontal speed, thus establishing a slower court. Additionally, surfaces with a higher bounce lead to slower play as players have more time to reach the ball. ITF Court Pace Rating uses both of these factors to determine how fast or slow a surface is.

The measurement of the Court Pace is carried out by means of special test equipment which includes a compressed air cannon and particular containers, controlled at the entrance and exit by special infrared devices.

This equipment, which can be used on all tennis surfaces whether on the court or in the laboratory, requires the use of a specialized technician.

For this reason, whether on-site or in the laboratory, all tests for ITF classification must be done by an ITF Accredited Laboratory.

A product included in the ITF classified surfaces list is included exclusively on the basis of the Court Pace and is classified for 3 years.

Verification of the biogenic carbon content

Biogenic carbon, a crucial component of sustainable products, comes from renewable sources such as biomass or animal by-products. In contrast to fossil carbon from oil, coal or natural gas, biogenic carbon is absorbed and stored in the natural life cycle of plants, trees and soils through the process of photosynthesis. Testing for biogenic carbon content enables companies to accurately distinguish biobased materials from synthetics made of nonrenewable resources allowing a clear communication of their environmental performance. TÜV SÜD conducted extensive testing on RED Plus natural clay infill materials used on tennis courts in accordance with the ASTM D6866 method. This method measures the level of carbon-14, also known as radiocarbon, contained in the materials confirming the biogenic carbon content of the company's product.
