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

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

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

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

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

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

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

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

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

Figure 3: Rebound - Test Method <strong>ITF</strong> TB 04/01<br />
To increase the accuracy of the rebound measurement and to reduce the effects of<br />
parallax, a shadow of the ball produced by a parallel beam of light is cast onto a<br />
frosted screen incorporating a graduated calibrated scale. The resulting image is<br />
recorded by a video camera together with indication of the reference number of the<br />
ball and bounce number being tested. Software records the images generated by the<br />
camera and tracks the trajectory of the ball, recording its highest point with reference<br />
to the calibrated scale.<br />
1.4 Test Procedure<br />
The <strong>ITF</strong> requires that 6 dozen balls are submitted for approval and from these the<br />
<strong>ITF</strong> randomly selects 2 dozen balls for testing. The ball containers are opened and<br />
the balls are then stored on racks in the controlled environment for a minimum of 24<br />
hours prior to testing. Each ball should be individually marked (preferably with a<br />
permanent marker) so that test results can be assigned to a particular ball.<br />
Following visual inspection, the test procedure should be carried out on each ball in<br />
the following sequence:<br />
i. Pre-compression. Apply to each of the 3 axes in succession, as described in<br />
Section 1.3.<br />
ii. Mass. Record the mass displayed and round to one decimal place for reporting<br />
purposes.<br />
12
iii.Size. Use ‘Go/No-Go’ gauge across at least 3 mutually perpendicular diameters.<br />
Care should be taken to ensure that the ball relies only upon its own weight to<br />
pass through a ring. Record Pass/Fail.<br />
iv.Deformation. Test once on each axis and record the results. Report mean, and<br />
maximum difference between readings, for each ball. See also Section 1.3. The<br />
test measures the deformation of a ball under a load of 18 pounds (8.165 kg)<br />
weight after a small initial load has been applied to compress the fabric cover<br />
material. See Figure 4. The ‘deformation’ is measured in two senses:<br />
a. When the load is first applied, i.e. the ‘forward’ deformation.<br />
b. Under the action of the load prior to it being removed and after the ball has<br />
been compressed further through a total distance of one inch (2.540 cm) -<br />
termed the ‘return’ deformation.<br />
Figure 4: Deformation - Test Method <strong>ITF</strong> TB 03/01<br />
Automated compression machine<br />
The automated compression machine (pictured overleaf) has been developed by<br />
the <strong>ITF</strong> as an alternative to the Stevens machine for testing tennis ball<br />
deformation.<br />
The computer-controlled machine replicates the operation of the Stevens machine,<br />
but provides significant improvements over the Stevens machine:<br />
a. Elimination of operator error in speed of testing, timing and results tabulation.<br />
b. Reduction of backlash (unmeasured losses in movement due to gaps between<br />
cog teeth).<br />
13
c. Graphical display of useful comparative information such as hysteresis losses.<br />
d. Carousel feed allowing up to 12 balls to be tested in 3 axes without operator<br />
assistance.<br />
e. The machine can also be used to pre-compress balls according to the Rules of<br />
<strong>Tennis</strong>.<br />
All of these advantages give the automated machine more functionality, accuracy<br />
and better reproducibility of results than the Stevens machine. For further<br />
information on the automated compression machines contact the <strong>ITF</strong> Technical<br />
Centre.<br />
v. Rebound. Record four valid measurements per ball (disregarding obvious ‘bad<br />
bounces’) and report mean rebound height.<br />
1.5 Tests for Other Ball Properties<br />
The <strong>ITF</strong> Technical Centre has routinely measured properties of tennis balls other<br />
than those required by the Rules of <strong>Tennis</strong>. These additional tests are carried out as<br />
part of the <strong>ITF</strong>’s policy of improving our understanding and definition of the sport in<br />
general and balls in particular.<br />
These tests are carried out on balls submitted to the <strong>ITF</strong> for <strong>ITF</strong> Approval testing and<br />
on balls obtained by the <strong>ITF</strong> from markets or tournaments.<br />
Some of the additional properties being measured include:<br />
a. Internal pressure of ball packaging (for pressurised balls). Measurements are<br />
taken using a standard pressure gauge with needle attachment and rubber seal.<br />
Results are recorded in lb/in 2 .<br />
b. Internal pressure of the ball. It has been established by the <strong>ITF</strong> Technical<br />
Commission that pressureless balls should have an internal pressure of no more<br />
than 1 psi. To ensure that this standard is met, all pressureless balls are tested.<br />
Measurements are taken using a standard pressure gauge with needle attachment.<br />
Results are recorded in lb/in 2 .<br />
14
c. Colour of fabric cover using a spectrophotometer. Colour properties as defined<br />
by the internationally recognised L*a*b and L*C*h standards are recorded under<br />
standardised D65-10° lighting conditions.<br />
Manufacturers who require further details of such tests should contact the <strong>ITF</strong><br />
Technical Centre.<br />
1.6 Calibration<br />
The apparatus used for the various tests must be regularly checked for accuracy of<br />
calibration as follows:<br />
Size. The ring gauges should be checked for accuracy against a known traceable<br />
reference every two years. The tolerance on ring gauge diameter should be +/-<br />
0.0025 inches (0.00635 cm).<br />
Mass. The weighing scales should be checked with calibration weights monthly and<br />
to traceable national standards. The accuracy of the scales should be +/- 0.001g.<br />
Rebound. Where the ‘video’ system is used for measuring rebound, the horizontal<br />
alignment of the light beam must be checked at the beginning and end of each test<br />
sequence. The accuracy of drop height and the frosted and transparent scales are<br />
checked monthly, to a tolerance of 0.1 inches (0.254 cm).<br />
Deformation. The Stevens machine should be checked daily for beam balance with<br />
the contact weight removed. It should be checked also for accuracy of platen<br />
displacement twice per year using 60 mm slip gauges. The tolerance on the platen<br />
displacement should be +/- 0.008 cm. The automated compression machine should<br />
be calibrated at six-month intervals using gauge blocks to the same tolerance as the<br />
Stevens machine. The automated compression machine should be compared against<br />
the Stevens machine monthly.<br />
1.7 Conditions for <strong>ITF</strong> Approval<br />
A manufacturer who wishes their ball to be considered for inclusion in the list of <strong>ITF</strong><br />
<strong>Approved</strong> tennis balls must submit a sample of balls for testing by the <strong>ITF</strong> in the<br />
manner described in detail above. The sample of balls submitted must be found to<br />
conform to the Rules of <strong>Tennis</strong> in all respects.<br />
A ball which passes the requirements of <strong>ITF</strong> testing and which gains <strong>ITF</strong> Approval is<br />
approved by the <strong>ITF</strong> only on the basis that it has been found to conform to the<br />
current Rules of <strong>Tennis</strong> and is therefore considered suitable for use in tournaments<br />
played according to the Rules of <strong>Tennis</strong>. <strong>ITF</strong> Approval does not imply any other<br />
form of approval.<br />
15
The <strong>ITF</strong> reserves the right to withdraw <strong>ITF</strong> Approval from any tennis balls at any<br />
time if it finds that balls are substantially different from the samples submitted for<br />
approval or, in the opinion of the <strong>ITF</strong> Technical Commission, such balls are not<br />
designed to meet the specification laid down in the Rules of <strong>Tennis</strong>, or if the<br />
approved balls fail to meet a reasonable quality standard.<br />
1.8 Market and tournament testing<br />
The <strong>ITF</strong> has additional specific requirements for tennis balls which have met the<br />
criteria for <strong>ITF</strong> Approval, to ensure that such balls continue to meet the standards<br />
laid down in the Rules of <strong>Tennis</strong>. A procedure is to be introduced by which balls will<br />
be randomly selected and tested from a variety of sources worldwide. <strong>ITF</strong> <strong>Approved</strong><br />
balls will be required to meet certain statistical criteria, as described below, in order<br />
to retain <strong>ITF</strong> <strong>Approved</strong> status and thereby qualify for use in tennis events played<br />
according to the Rules of <strong>Tennis</strong> (see Rule 3).<br />
The minimum sample size for balls tested under this procedure is 12. A ball which<br />
fails to conform to one or more of the specifications laid down in the Rules of<br />
<strong>Tennis</strong> will be counted as a single failure.<br />
The criteria by which randomly selected samples of balls will be assessed is as<br />
follows:<br />
No. of balls<br />
in sample<br />
12<br />
24<br />
36<br />
No. of balls failing<br />
to conform<br />

The above criteria are based on the normal distribution curve with action being taken<br />
in the form of either a warning letter to the manufacturer/distributor, or removal of<br />
<strong>ITF</strong> Approval at +/- 1 and 2 sigma respectively. Criteria for other sample sizes are<br />
calculated accordingly.<br />
Removal of <strong>ITF</strong> Approval is at all times at the sole discretion of the <strong>ITF</strong>. Such<br />
action is normally only taken based on the results of more than one sample of balls<br />
from a market or tournament. The <strong>ITF</strong> reserves the right to withdraw <strong>ITF</strong> Approval<br />
from any ball at any time during the next 12 months.<br />

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

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

2 “Appearance” relates only to the form of the uppermost surface material and not<br />
other characteristics (e.g. colour).<br />
3 Used only when the material itself forms the playing surface. When used as a base<br />
for other surfaces (e.g. acrylic), reference will be made only to the playing surface.<br />
4 This term denotes a class of natural surfaces that is constructed from naturallyderived<br />
materials, and include a fine gritty material as the uppermost (playing) layer,<br />
e.g. fast-dry.<br />
