What is The International Tennis Federation?
The International Tennis Federation (ITF) is the world wide governing body of
tennis and has the following broad areas of responsibility:
•
•
•
•
•
administering and regulating the game
organising international competitions
structuring the game
developing the game
promoting the game.
The ITF Technical Commission is responsible for monitoring developments in
equipment technology in order to protect the nature of the game of tennis at all
levels. As custodians of the Rules of Tennis, the ITF has the sometimes difficult
task of judging whether innovations in tennis equipment may bring about a benefit to
those who play, or whether such developments constitute a threat to the nature of the
game.
In 1997, the ITF created its own Technical Centre with a laboratory and staff whose
task it is to carry out testing and research into all aspects of the game, and to provide
support to the ITF Technical Commission and other ITF Committees on decisions
relating to technical issues. This facility has recently been expanded and is now the
world’s leading tennis research and testing laboratory.
The mission of the ITF Technical Centre is:
to protect the nature of tennis by actively preserving the skills
traditionally required to play the game, and, to encourage innovation
and improvements which maintain the challenge of the game and
make it more exciting to play and watch.

(i) INTRODUCTION
The official International Tennis Federation (ITF) Rules of Tennis requires that any
ball which is to be considered for use in any tournament which is played according
to the Rules of Tennis, shall be named on the official list of balls which have been
tested and approved as conforming to the specifications laid down in the Rules of
Tennis and as issued by the ITF.
Following a two-year experimental period, from 1 January 2002 the Rules of Tennis
(see Rule 3 and Appendix I) were officially amended to allow new types of ball – a
fast-speed ball (Type 1) and a slow-speed ball (Type 3). The two new types of ball
are designed to have different performance characteristics derived from their
dynamic and aerodynamic properties.
• Type 1 (fast-speed) is identical to the standard ball except that it is harder. A
lower-bouncing, faster ball.
• Type 2 (medium-speed) is the standard ball and is identical to the specification
that existed prior to 2000. A medium-bouncing ball.
• Type 3 (slow-speed) is identical to the standard ball except that it is
approximately 6% larger in diameter. A higher-bouncing, slower ball.
Ball type 2
Ball type 3
Ball type 1
To help determine which ball should be used on which surface, the ITF has
introduced an official Court Surface Classification scheme.
As part of the
assessment procedure, each surface product is awarded a Surface Pace Rating, which
classifies it as a slow (Category 1), medium/medium fast (Category 2) or fast
(Category 3) surface.
It should be noted that the Type 3 ball is also permitted and recommended for play at
High Altitude on any court surface type.
Both the tennis ball approval ruling and the Court Surface Classification scheme
have been introduced as part of an initiative to provide further understanding and
international standardisation of the equipment used in tennis. They will be of
significance to players, national associations, referees, tournament organisers and
tennis ball manufacturers worldwide.
1
The ITF Technical Centre commenced its ball testing procedure for ITF Approval
for the calendar year 2007 on 1 June 2006. The testing procedure for balls which are
to be included on the official list of 2008 ITF Approved balls will commence on 1
June 2007.
The testing of court surface products is undertaken by ITF Accredited Laboratories.
ITF Court Surface Classification is valid for a period of three years – the date of
expiry is listed separately for each product.
All balls approved and surface products classified by 5 January 2007 are listed in
this booklet. As more balls and surface products are tested and approved/classified,
they will be included on the ITF web sites www.itftennis.com and
www.itftennis.com/technical.
Companies requiring detailed information on the testing procedures for applying for,
and receiving, ITF Approval for tennis balls or ITF Court Surface Classification
should contact the ITF Technical Centre.

(ii) THE RULES OF TENNIS – RULE 3 AND APPENDIX I – THE BALL
(Effective 1 January 2007)
Balls, which are approved for play under the Rules of Tennis, must comply with the
specifications in Appendix I.
The International Tennis Federation shall rule on the question of whether any ball or
prototype complies with Appendix I or is otherwise approved, or not approved, for play.
Such ruling may be taken on its own initiative, or upon application by any party with a
bona fide interest therein, including any player, equipment manufacturer or National
Association or members thereof. Such rulings and applications shall be made in
accordance with the applicable Review and Hearing Procedures of the International
Tennis Federation (see Appendix VI).
The event organisers must announce in advance of the event:
a. The number of balls for play (2, 3, 4 or 6).
b. The ball change policy, if any.
Ball changes, if any, can be made either:
i. After an agreed odd number of games, in which case, the first ball change in the
match shall take place two games earlier than for the rest of the match, to make
allowance for the warm-up. A tie-break game counts as one game for the ball
change. A ball change shall not take place at the beginning of a tie-break game. In
this case, the ball change shall be delayed until the beginning of the second game of
the next set; or
ii. At the beginning of a set
If a ball gets broken during play, the point shall be replayed.
Case 1: If a ball is soft at the end of a point, should the point be replayed?
Decision: If the ball is soft, not broken, the point shall not be replayed.
Note: Any ball to be used in a tournament which is played under the Rules of Tennis,
must be named on the official ITF list of approved balls issued by the International
Tennis Federation.
APPENDIX I - THE BALL
a.
The ball shall have a uniform outer surface consisting of a fabric cover and shall
be white or yellow in colour. If there are any seams they shall be stitchless.
b.
More than one type of ball is specified. The ball shall conform to the
requirements shown in the table below.
c.
All tests for rebound, size and deformation shall be made in accordance with the
regulations below.

Notes:
1
This ball may be pressurised or pressureless. The pressureless ball shall have an internal
pressure that is no greater than 1 psi (7 kPa) and may be used for high altitude play above
4,000 feet (1,219 m) above sea level and shall have been acclimatised for 60 days or
more at the altitude of the specific tournament.
2
This ball is also recommended for high altitude play on any court surface type above
4,000 feet (1,219 m) above sea level.
3
This ball is pressurised and is an additional ball specified for high altitude play above
4,000 feet (1,219 m) above sea level only.
4
The deformation shall be the average of a single reading along each of three
perpendicular axes. No two individual readings shall differ by more than .030 inches
(.076 cm).
REGULATIONS FOR MAKING TESTS
i.
Unless otherwise specified all tests shall be made at a temperature of
approximately 68º Fahrenheit (20º Celsius), a relative humidity of approximately
60% and, unless otherwise specified, an atmospheric pressure of approximately
30 inches Hg (102 kPa). All balls shall be removed from their container and kept
at the recognised temperature and humidity for 24 hours prior to testing, and shall
be at that temperature and humidity when the test is commenced.
ii.
Other standards may be fixed for localities where the average temperature,
humidity or average barometric pressure at which the game is being played differ
materially from 68º Fahrenheit (20º Celsius), 60% relative humidity and 30 inches
Hg (102 kPa) respectively.
4
Applications for such adjusted standards may be made by any National
Association to the International Tennis Federation and, if approved, shall be
adopted for such localities.
iii.
In all tests for diameter, a ring gauge shall be used consisting of a metal plate,
preferably non-corrosive, of a uniform thickness of one-eighth of an inch (0.318
cm). In the case of Ball Type 1 (fast speed) and Ball Type 2 (medium speed) balls
there shall be two circular openings in the plate measuring 2.575 inches (6.541
cm) and 2.700 inches (6.858 cm) in diameter respectively. In the case of Ball
Type 3 (slow speed) balls there shall be two circular openings in the plate
measuring 2.750 inches (6.985 cm) and 2.875 inches (7.303 cm) in diameter
respectively. The inner surface of the gauge shall have a convex profile with a
radius of one-sixteenth of an inch (0.159 cm). The ball shall not drop through the
smaller opening by its own weight in any orientation and shall drop through the
larger opening by its own weight in all orientations.
iv.
In all tests for deformation conducted under Rule 3, the machine designed by
Percy Herbert Stevens and patented in Great Britain under Patent No. 230250,
together with the subsequent additions and improvements thereto, including the
modifications required to take return deformations, shall be employed. Other
machines may be specified which give equivalent readings to the Stevens
machine and these may be used for testing ball deformation where such machines
have been given approval by the International Tennis Federation.
v. The procedure for carrying out tests is as follows and should take place in the
order specified:
a. Pre-compression – before any ball is tested it shall be steadily compressed
by approximately one inch (2.54 cm) on each of three diameters at right
angles to one another in succession; this process to be carried out three
times (nine compressions in all). All tests are to be completed within two
hours of pre-compression.
b. Weight (mass) test.
c. Size test (as in paragraph iii. above).
d. Deformation test – the ball is placed in position on the modified Stevens
machine so that neither platen of the machine is in contact with the cover
seam. The contact weight is applied, the pointer and the mark brought
level, and the dials set to zero. The test weight is placed on the beam in a
position that is equivalent to a load of 18 lb (8.2 kg) on the ball, after
which the wheel is turned at a uniform speed such that five seconds elapse
from the instant the beam leaves its seat until the pointer is brought level
with the mark. When turning ceases the reading is recorded (forward
deformation). The wheel is turned again until figure ten is reached on the
scale (one inch {2.54 cm} deformation). The wheel is then rotated in the
opposite direction at a uniform speed (thus releasing pressure) until the
5
beam pointer again coincides with the mark. After waiting ten seconds,
the pointer is adjusted to the mark if necessary. The reading is then
recorded (return deformation). This procedure is repeated on each ball
across the two diameters at right angles to the initial position and to each
other.
e. Rebound test (as above) – the ball is dropped from 100 inches (254 cm)
onto a smooth rigid and horizontal surface. Measurements of both drop
height and rebound height are to be taken from the surface to the bottom
of the ball.
CLASSIFICATION OF COURT SURFACE PACE
The ITF test method used for determining the pace of a court surface is test method ITF
CS 01/01 (ITF Surface Pace Rating) as described in the ITF publication entitled “An
initial ITF study on performance standards for tennis court surfaces”.
Court surfaces which are found to have an ITF Surface Pace Rating of between 0 and 35
shall be classified as being Category 1 (slow pace). Examples of court surface types
which conform to this classification will include most clay courts and other types of
unbound mineral surface.
Court surfaces which are found to have an ITF Surface Pace Rating of between 30 and
45 shall be classified as being Category 2 (medium/medium-fast pace). Examples of
court surface types which conform to this classification will include most hard courts
with various acrylic type coatings plus some textile surfaces.
Court surfaces which are found to have an ITF Surface Pace Rating of over 40 shall be
classified as being Category 3 (fast pace). Examples of court surface types which
conform to this classification will include most natural grass, artificial turf and some
textile surfaces.
Note: The proposed overlap in ITF Surface Pace Rating values for the above categories
is to allow some latitude in ball selection.
Case 1: Which ball type should be used on which court surface?
Decision: 3 different types of balls are approved for play under the Rules of Tennis,
however:
a.
Ball Type 1 (fast speed) is intended for play on slow pace court surfaces
b.
Ball Type 2 (medium speed) is intended for play on medium/medium-fast pace
court surfaces
c.
Ball Type 3 (slow speed) is intended for play on fast pace court surfaces

(iii) SPECIFICATIONS FOR STAGE 1, 2 AND 3 TENNIS BALLS
Tennis balls have been developed to increase the speed at which beginner and
recreational children and adult players learn the game, which thus enhances their
enjoyment of tennis. This has been achieved by the manufacture of tennis balls
which are designed to be ‘slower’ and which therefore allow greater opportunity for
players to rally.
Three such groups of balls have been introduced: Stage 3 (red), Stage 2 (orange)
and Stage 1 (green). Specifications for the Stage 2 and Stage 1 balls are shown in the
table below.

(1.346 - 1.473 m)
0.220 - 0.290 inches
(0.559 - 0.737 cm)
Notes:
There is currently no specification for return deformation.
There is currently no limit on the difference between individual forward deformation
readings.
All tests for size, mass, rebound height and forward deformation should be carried
out in accordance with the official procedures described in Appendix I of the Rules
of Tennis.
There are 3 sub-categories of Stage 3 (red) ball:
1. Standard construction.
2. Cut foam.
3. Moulded foam.
During 2007, the ITF intends to introduce specifications for Stage 3 balls. Due to
the high compressibility of Stage 3 balls, this will be limited to size, mass and
rebound in the first instance. Thus, the approval of balls in the Stage 3 (red)
category will be supplemented through play testing by a panel of experts, annually in
December.
Information regarding approval of all introductory balls (including Stage 3) can be
obtained from the ITF Technical Centre. The list of 2007 ITF Approved Stage 1, 2
and 3 tennis balls is published in Section A of this booklet.

(iv) ISO 9001:2000
All testing, administration and calibration procedures adopted by the ITF Technical
Centre in testing tennis balls for ITF Approval, and court surfaces for ITF
Classification, are carried out and managed according to ISO 9001:2000.
(v) FUTURE DEVELOPMENT OF TESTING METHODS, TENNIS
BALL SPECIFICATIONS AND PACE RATING VALUES
The ITF reserves the right to amend and update the information given in this
document without prior notice. As a general rule, amendments will be made only
after consultation with interested parties.

SECTION A – THE BALL
1.
PROCEDURES AND GUIDELINES FOR THE TESTING
OF TENNIS BALLS FOR ITF APPROVAL
The properties of tennis balls are specified by the International Tennis Federation to
generate uniformity, and consistency in performance. Special testing facilities and
apparatus are necessary to accurately measure these properties, and this section
details the required test conditions and procedures.
The following notes are provided as additional information for those involved in the
testing or evaluation of tennis balls and should be read in conjunction with the
specification for a tennis ball and regulations for making tests, as described in Rule 3
and Appendix I of the Rules of Tennis.
1.1
General Considerations
A tennis ball consists of a hollow rubber core (which may or may not be pressurised)
covered by a textile material composed of wool, nylon and cotton. Because the
properties of the rubber core and its internal gas are affected by temperature, the
properties of the cover by atmospheric moisture and the effective internal pressure
by the external atmospheric pressure, it is important that ball testing is carried out in
a controlled atmosphere where at least temperature and humidity are standardised. It
is not practical to control atmospheric pressure, which is primarily dependent on
altitude and so it is desirable that any testing station should be at or near sea level so
that test data are comparable. In any case, atmospheric pressure should always be
recorded when ball tests are made.
The following conditions are specified for testing by the ITF:
Temperature
Relative humidity
Atmospheric pressure
20°C (68°F)
60%
30 inches Hg (760 mm)
While no tolerances are given in the specification contained in the Rules of Tennis,
limits of +/-2°C for temperature, +/-5% for humidity and +/-25mm Hg have been
established.
1.2
Environmental Conditions
To meet the environmental requirements noted above, a well-insulated room with
double-glazed windows not exposed to sunshine, and a double-door ‘air-lock’
arrangement to reduce air leakage on entry and exit, are recommended.
9
Control of temperature and humidity should be provided by a temperature and
humidity control unit of an appropriate specification with regard to thermal
capability and control accuracy. Such a conditioner normally consists of two
component parts: an internal fan unit and an external condenser unit with connecting
piping.
The specification of this conditioning equipment is primarily related to removing
excess heat and moisture generated within the environment by electrical equipment
and the bodies of the technicians working there. Such equipment must be capable of
controlling the testing environment within the tolerances set down in Section 1.1.
As well as controlling the environment, it should also be independently monitored,
and so temperature and humidity recorders together with a barometer are necessary.
A permanent record of environmental conditions during conditioning and test should
be kept.
Balls selected for testing should be stored under such controlled conditions and
exposed to circulating air for ‘conditioning’ for the required 24 hours prior to
testing.
1.3
Laboratory and Test Equipment
Mass - Test Method ITF TB 01/01: An electronic laboratory balance measuring in
grams to at least two decimal places, to a capacity of 100 grams.
Size - Test Method ITF TB 02/01: Equipment consists of two circular gauges
defining the limits of ball diameter designated ‘Go/No-Go’ through which a ball will
drop/not drop under its own weight. See Figure 1.
Deformation - Test Method ITF TB 03/01: This is measured using a ‘modified’
Stevens Machine.
Prior to deformation testing the ball must be pre-compressed three times on each of 3
perpendicular axes through a distance of one inch (2.540 cm) in order to remove any
‘set’ in the ball. One pre-compression should occur on each axis in succession, until
9 pre-compressions in all are completed. This is carried out on a ‘pre-compression
jig’. See Figure 2.
10
Ball Type 1 and Type 2
(1) A ball must pass through a ring
gauge with internal diameter
2.700 inches (6.858 cm) under
its own weight.
(2) A ball must not pass through a ring
gauge with internal diameter 2.575
inches (6.541 cm) under its own
weight.
Ball Type 3
(1) A ball must pass through a ring (2) A ball must not pass through a ring

Figure 2: Pre-Compression - Test Method ITF TB 03/01
Rebound - Test Method ITF TB 04/01: This consists of dropping a ball through a
height of 100 inches (254 cm) (measured from the bottom of the ball) onto a rigid
block of high mass and measuring the rebound height (again measured to the bottom
of the ball). The method adopted by the ITF to accurately measure the ball rebound
11
height involves automatic tracking of the rebound by computer software.

To increase the accuracy of the rebound measurement and to reduce the effects of
parallax, a shadow of the ball produced by a parallel beam of light is cast onto a
frosted screen incorporating a graduated calibrated scale. The resulting image is
recorded by a video camera together with indication of the reference number of the
ball and bounce number being tested. Software records the images generated by the
camera and tracks the trajectory of the ball, recording its highest point with reference
to the calibrated scale.
1.4
Test Procedure
The ITF requires that 6 dozen balls are submitted for approval and from these the
ITF randomly selects 2 dozen balls for testing. The ball containers are opened and
the balls are then stored on racks in the controlled environment for a minimum of 24
hours prior to testing. Each ball should be individually marked (preferably with a
permanent marker) so that test results can be assigned to a particular ball.
Following visual inspection, the test procedure should be carried out on each ball in
the following sequence:
i. Pre-compression. Apply to each of the 3 axes in succession, as described in
Section 1.3.
ii. Mass. Record the mass displayed and round to one decimal place for reporting
purposes.
12
iii.Size. Use ‘Go/No-Go’ gauge across at least 3 mutually perpendicular diameters.
Care should be taken to ensure that the ball relies only upon its own weight to
pass through a ring. Record Pass/Fail.
iv.Deformation. Test once on each axis and record the results. Report mean, and
maximum difference between readings, for each ball. See also Section 1.3. The
test measures the deformation of a ball under a load of 18 pounds (8.165 kg)
weight after a small initial load has been applied to compress the fabric cover
material. See Figure 4. The ‘deformation’ is measured in two senses:
a. When the load is first applied, i.e. the ‘forward’ deformation.
b. Under the action of the load prior to it being removed and after the ball has
been compressed further through a total distance of one inch (2.540 cm) termed the ‘return’ deformation.
Figure 4: Deformation - Test Method ITF TB 03/01
Automated compression machine
The automated compression machine (pictured overleaf) has been developed by
the ITF as an alternative to the Stevens machine for testing tennis ball
deformation.
The computer-controlled machine replicates the operation of the Stevens machine,
but provides significant improvements over the Stevens machine:
a. Elimination of operator error in speed of testing, timing and results tabulation.
b. Reduction of backlash (unmeasured losses in movement due to gaps between
cog teeth).
13
c. Graphical display of useful comparative information such as hysteresis losses.
d. Carousel feed allowing up to 12 balls to be tested in 3 axes without operator
assistance.
e. The machine can also be used to pre-compress balls according to the Rules of
Tennis.
All of these advantages give the automated machine more functionality, accuracy
and better reproducibility of results than the Stevens machine. For further
information on the automated compression machines contact the ITF Technical
Centre.
v. Rebound. Record four valid measurements per ball (disregarding obvious ‘bad
bounces’) and report mean rebound height.
1.5
Tests for Other Ball Properties
The ITF Technical Centre has routinely measured properties of tennis balls other
than those required by the Rules of Tennis. These additional tests are carried out as
part of the ITF’s policy of improving our understanding and definition of the sport in
general and balls in particular.
These tests are carried out on balls submitted to the ITF for ITF Approval testing and
on balls obtained by the ITF from markets or tournaments.
Some of the additional properties being measured include:
a. Internal pressure of ball packaging (for pressurised balls). Measurements are
taken using a standard pressure gauge with needle attachment and rubber seal.
Results are recorded in lb/in2.
b. Internal pressure of the ball. It has been established by the ITF Technical
Commission that pressureless balls should have an internal pressure of no more
than 1 psi. To ensure that this standard is met, all pressureless balls are tested.
Measurements are taken using a standard pressure gauge with needle attachment.
Results are recorded in lb/in2.
14
c. Colour of fabric cover using a spectrophotometer. Colour properties as defined
by the internationally recognised L*a*b and L*C*h standards are recorded under
standardised D65-10° lighting conditions.
Manufacturers who require further details of such tests should contact the ITF
Technical Centre.
1.6
Calibration
The apparatus used for the various tests must be regularly checked for accuracy of
calibration as follows:
Size. The ring gauges should be checked for accuracy against a known traceable
reference every two years. The tolerance on ring gauge diameter should be +/0.0025 inches (0.00635 cm).
Mass. The weighing scales should be checked with calibration weights monthly and
to traceable national standards. The accuracy of the scales should be +/- 0.001g.
Rebound. Where the ‘video’ system is used for measuring rebound, the horizontal
alignment of the light beam must be checked at the beginning and end of each test
sequence. The accuracy of drop height and the frosted and transparent scales are
checked monthly, to a tolerance of 0.1 inches (0.254 cm).
Deformation. The Stevens machine should be checked daily for beam balance with
the contact weight removed. It should be checked also for accuracy of platen
displacement twice per year using 60 mm slip gauges. The tolerance on the platen
displacement should be +/- 0.008 cm. The automated compression machine should
be calibrated at six-month intervals using gauge blocks to the same tolerance as the
Stevens machine. The automated compression machine should be compared against
the Stevens machine monthly.
1.7
Conditions for ITF Approval
A manufacturer who wishes their ball to be considered for inclusion in the list of ITF
Approved tennis balls must submit a sample of balls for testing by the ITF in the
manner described in detail above. The sample of balls submitted must be found to
conform to the Rules of Tennis in all respects.
A ball which passes the requirements of ITF testing and which gains ITF Approval is
approved by the ITF only on the basis that it has been found to conform to the
current Rules of Tennis and is therefore considered suitable for use in tournaments
played according to the Rules of Tennis. ITF Approval does not imply any other
form of approval.
15
The ITF reserves the right to withdraw ITF Approval from any tennis balls at any
time if it finds that balls are substantially different from the samples submitted for
approval or, in the opinion of the ITF Technical Commission, such balls are not
designed to meet the specification laid down in the Rules of Tennis, or if the
approved balls fail to meet a reasonable quality standard.
1.8
Market and tournament testing
The ITF has additional specific requirements for tennis balls which have met the
criteria for ITF Approval, to ensure that such balls continue to meet the standards
laid down in the Rules of Tennis. A procedure is to be introduced by which balls will
be randomly selected and tested from a variety of sources worldwide. ITF Approved
balls will be required to meet certain statistical criteria, as described below, in order
to retain ITF Approved status and thereby qualify for use in tennis events played
according to the Rules of Tennis (see Rule 3).
The minimum sample size for balls tested under this procedure is 12. A ball which
fails to conform to one or more of the specifications laid down in the Rules of
Tennis will be counted as a single failure.
The criteria by which randomly selected samples of balls will be assessed is as
follows:
No. of balls
in sample
No. of balls failing
to conform
Action

0–1
2–3
4+

3–7
8+
None

36
0–3
4 – 11

None
Letter of warning
Removal of ITF Approval
The above criteria are based on the normal distribution curve with action being taken
in the form of either a warning letter to the manufacturer/distributor, or removal of
ITF Approval at +/- 1 and 2 sigma respectively. Criteria for other sample sizes are
calculated accordingly.
Removal of ITF Approval is at all times at the sole discretion of the ITF. Such
action is normally only taken based on the results of more than one sample of balls
from a market or tournament. The ITF reserves the right to withdraw ITF Approval
from any ball at any time during the next 12 months.

SECTION B – THE COURT SURFACE
1.
PROCEDURES AND GUIDELINES FOR SURFACE PACE
PRODUCT ASSESSMENT AND CLASSIFICATION
When commissioning a Surface Pace assessment, the company requesting the tests
must provide a detailed specification of the surface construction. In order to ensure
an accurate assessment of the surface, tests, wherever possible, should be made on
the actual court. Where it is not possible to undertake Surface Pace measurements
on site, tests may be made in an ITF Accredited laboratory on representative samples
of the surface. Unless the surface is designed to be damp/wet when in its optimum
condition, tests should be made with the surface in a dry condition.
1.1
Test Procedure
i.
Tests on site. These must be undertaken on a court that is less than four
months old. Prior to the tests being made, the courts must be prepared using
the manufacturer’s, supplier’s or contractor’s approved procedures. The body
requesting the testing must undertake this work. Tests must be made on the
court in four pre-determined positions as shown in Figure 5.
Figure 5: Test Site Positions
ii.
Tests in the laboratory. The ITF requires that four samples of the surface
product, each measuring a minimum of 0.5 m x 0.5 m in area, are submitted
by the manufacturer directly to an ITF Accredited laboratory, together with a
detailed specification of the court/surface construction. The laboratory must
select three random samples for assessment.
1.2
Test Apparatus and Methods
Test apparatus consists of:
i.
A means of projecting a ball at the specified angle and velocity onto the
surface without imparting spin greater than 3 revolutions per second.
29
ii.
A means of monitoring the trajectory of the ball before and after impact such
that its velocity can be measured to an accuracy of +/- 0.01 m/s and angle of
+/-0.1°.
iii.
Three standard ‘test’ balls.
Conditioning and test temperature. For tests in the laboratory, the test specimen
must be conditioned at the test temperature for a minimum of 3 hours. Unless
otherwise specified, the test temperature should be 23 +/- 2°C. For ‘on-site’ testing
measurements should be taken of the prevailing ambient temperature and humidity.
Test Method ITF CS 01/01. The ball projecting apparatus should be adjusted to
deliver the ball at the specified angle and velocity, by carrying out trial runs. Tests
should be carried out at an angle of incidence of 16 +/- 2° and a velocity of 30 +/- 2
m/s. Each ball must be projected onto the test specimen three times. This is to
stabilise each ball and remove any ‘set’ which can occur in tennis balls stored for
any length of time. If the surface is disturbed or damaged as a result of the test, the
impact location should be changed or surface restored before the next test. The test
should be carried out nine times, by projecting each of the three balls three times in
the same sequence onto the test specimen. The ball velocity and angle both before
and after impact should be recorded. The tests should all be carried out as soon as is
reasonable to minimise changes in the ambient conditions. If the surface has an
inherent directional pattern, such as the lay of the pile of artificial turf, etc., the tests
should be carried out such that a set of readings can be obtained in directions giving
maximum and minimum values of angle rebound.

Conditions for ITF Surface Pace Classification Listing
The ITF procedures for obtaining Surface Pace Product Assessment and inclusion on
the ITF list of Classified Tennis Court Surfaces are contained within a separate
document entitled “Court Surface Pace Classification Scheme”, available on request
from the ITF Technical Centre.
A manufacturer, supplier or contractor who wishes their court surface to be included
on the list of ITF Classified surface pace products must first appoint an ITF
Accredited Laboratory to assess their surface in the manner described above.
Following receipt of an ITF Surface Pace Test Report prepared by the laboratory, an
application must be made to the ITF for Classification Listing, which is valid for a
period of three years.
A surface product included on the list of ITF Classified Court Surfaces is classified
by the ITF purely on the basis of its surface pace rating. ITF Classification listing
does not imply any form of surface product approval.
Upon expiry of the classification period, a manufacturer may apply for
reclassification, the details of which are available from the ITF Technical Centre.
