Table tennis regulations

The regulations of a sport are a little more complicated. An official regulation wouldn’t be (in terms of football) scoring a goal. A regulation are the main rules of a certain sport. E.g. the size of a football pitch at professional level.
1) THE TABLE
The upper surface of the table, known as the playing surface, shall be rectangular, 2.74m long and 1.525m wide, and shall lie in a horizontal plane 76cm above the floor.
The playing surface shall not include the sides of the table top.
The playing surface may be of any material and shall yield a uniform bounce of about 23cm when a standard ball is dropped on to it from a height of 30cm.
The playing surface shall be uniformly dark coloured and matt, but with a white side line, 2cm wide, along each 2.74m edge and a white end line, 2cm wide, along each 1.525m edge.
The playing surface shall be divided into 2 equal courts by a vertical net
running parallel with the end lines, and shall be continuous over the whole area of each court.
For doubles, each court shall be divided into 2 equal half-courts by a white
centre line, 3mm wide, running parallel with the side lines; the centre line shall be regarded as part of each right half-court.
2) THE NET ASSEMBLY
The net assembly shall consist of the net, its suspension and the supporting
posts, including the clamps attaching them to the table. 2) The net shall be suspended by a cord attached at each end to an upright post
15.25cm high, the outside limits of the post being 15.25cm outside the side line.
The top of the net, along its whole length, shall be 15.25cm above the playing surface.
The bottom of the net, along its whole length, shall be as close as possible to
the playing surface and the ends of the net shall be as close as possible to the supporting posts.
3) THE BALL
The ball shall be spherical, with a diameter of 38mm.
The ball shall weigh 2.5gm.
The ball shall be made of celluloid or similar plastics material and shall be white or orange, and matt.
4) THE RACKET
The racket may be of any size, shape or weight but the blade shall be flat and rigid.
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 fiber, glass fiber or compressed paper, but shall not be thicker than 7.5% of the total thickness or 0.35mm, whichever is the smaller.
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 2 mm, or sandwich rubber, with pimples inwards or outwards, having a total thickness including adhesive of not more than 4 mm.
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.
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.
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.
The blade, any layer within the blade and any layer of covering material or adhesive shall be continuous and of even thickness.
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 matt, bright red on one side and black on the other.
Slight deviations from continuity of surface or uniformity of colour due to accidental damage or wear may be allowed provided that they do not significantly change the characteristics of the surface.
