Examples are: abusive language, deliberately breaking the ball or hitting it out of the playing area, kicking the table or surrounds or disrespect to match officials.

19.2.2 If at any time a player or coach commits a serious offence the umpire shall suspend play and report immediately to the referee. For less serious offences the umpire may, on the first occasion, hold up a yellow card and warn the offender that any further offence is liable to incur penalties.

19.2.3 If a player who has been warned commits a second offence in the same individual or team match, the umpire shall award one point to the player's opponent and after a further offence he shall award two points to his opponent, each time holding up a yellow and a red card together.
