Table tennis table
A table tennis table,that can be used at tournaments, has got a length of 2,74m (9ft) and a width of 1,525m (5ft). The table top has to be exactly 0,76m above the ground. The table is divided by the net set into two equal halves with the dimensions of 1,37m x 1,525m (4,5ft x 5ft). When a table tennis ball has been dropped from a height of 30cm the rebound has to be between 0,23m and 0,26m. Each table top half is divided by a 3mm white line (centre line) lengthwise into 2 halves. At all edges of the table there are 20mm white lines: the base line (parallel to the net) and the side lines (at right angles to the net). The surface of the table may not reflect and has to be dark. Usually table tennis tops are of dark green or blue colour.
The table tennis table has to comply with the EN 14468 (until 2005 DIN 7898). Since 1995 all manufacturers of table tennis tables have to apply for an admission with the German Table Tennis Association (DTTB).
Higher stabil ity of the tabletops is provided by tabletop connections and net set.
Depending on the field of use (Indoor / Outdoor) SPONETA is using for the production of the table tennis tables either highly-quality coated 3tecWOOD tops or melamine tops.
The thickness of the top affects the ball rebound, the surface coating the degree of gloss and the coefficient of sliding friction the movement of the ball and the abrasion resistance.
Time game (colloquially for change method) is used when one set has not been finished after 10 minutes and within this set have not been played at least 18 points. With the change method the right to serve is changing after each point. The winning point is given as in the normal match – with one exception: when the opponent of the server has returned the ball 13 times successfully he gets the point. This means the ball is played back and forth 13 times maximum. For further sets to be played the change method is used again.
The topspin is a playing technique that gives the ball a strong forward spin. Here the ball must be touched even more than with spin. The forward movement is much more pronounced than the upward movement.
Types of grip
It is a grip technique that is preferably used in the Asian region and in which the grip is held with the blade down between thumb and forefinger.
This grip technique is mainly used in Europe. The grip is held in the hand with the blade upwards with the forefinger resting on the backhand of the bat for stabilization.
