Teams can have a maximum of three substitutes.
Should a team become incomplete during a match and no substitutes are available, this team is declared the loser of the remaining sets. The team keeps the sets and points they have already won. FIVB exceptional substitutions are allowed. The lines, which indicate the playing area, are five centimetres wide and are part of the court. The mesh of the net is preferably made of a dark material.
