3.4.1 The racket may be of any size, shape or weight but the blade shall be
flat and rigid.
3.4.2 At least 85% of the blade by thickness shall be of natural wood; an
adhesive layer within the blade may be reinforced with fibrous material
such as carbon fibre, glass fibre or compressed paper, but shall not
be thicker than 7.5% of the total thickness or 0.35mm, whichever is
the smaller.
3.4.3 A side of the blade used for striking the ball shall be covered with
either ordinary pimpled rubber with pimples outwards having a total
thickness including adhesive of not more than 2mm, or sandwich rubber
with pimples inwards or outwards having a total thickness including
adhesive of not more than 4mm.
3.4.3.1 Ordinary pimpled rubber is a single layer of non-cellular rubber,
natural or synthetic, with pimples evenly distributed over its surface
at a density of not less than 10 per sq cm and not more than 50 per sq
cm.
3.4.3.2 Sandwich rubber is a single layer of cellular rubber covered with a
single outer layer of ordinary pimpled rubber, the thickness of the
pimpled rubber not being more than 2 mm.
3.4.4 The covering material shall extend up to but not beyond the limits of
the blade, except that the part nearest the handle and gripped by the
fingers may be left uncovered or covered with any material.
3.4.5 The blade, any layer within the blade and any layer of covering material
or adhesive shall be continuous and of even thickness.
3.4.6 The surface of the covering material on a side of the blade, or of a
side of the blade if it is left uncovered, shall be uniformly dark-
coloured and matt; any trimming round the edge of the blade shall be
matt and no part of it shall be white.
3.4.7 Slight deviations from continuity of surface or uniformity of colour due
to accidental damage, wear or fading may be allowed provided that they
do not significantly change the characteristics of the surface.
3.4.8 At the start of a match and whenever he changes his racket during a match
a player shall show his opponent and the umpire the racket he is about
to use and shall allow them to examine it.
