There are two different kinds of regular interruptions: technical time-outs and team-time-outs. All time-outs last 30 seconds (but are administered over 60 seconds). During the time-outs, the players have to be close to their respective bench.
Technical time-outs are given when the sum of the points that have been played equals a multiple of 21 (e.g. 12:9, 14:7, …), except in a deciding set (no technical time-out).
Each team is allowed one time-out per set. The captain has to request the time-out by using the official hand signal once the ball is out of play. Both teams are allowed to request their time-outs during the same intermission.
In case of injury or illness of one of the players, he can ask for a medical time-out which might take up to 5 minutes. The countdown starts once the medical personnel arrives at the court. If there is no official medical personnel, or the player wants to be treated by his own physician, the countdown starts once the medical time-out is granted.
The player is allowed to leave the court for treatment. In this situation, the second referee has to accompany the player.
In case the player is not able to continue the match after the medical time-out, the team has to be declared incomplete.
