2018 USPA Rule Changes
14. DURATION OF PERIODS
b. In each period of the game, at the end of 7 minutes of elapsed time, a single horn or bell will sound to indicate that up to 30 seconds of overtime remain in the period. At the end of the overtime portion of the period, a horn or bell will sound twice to terminate the period.
(1) Except for the final period of regulation play, each period will terminate following the 7-minute horn or bell, when the ball goes out of play, a goal is scored, or the Umpire(s) whistle sounds. When played on a boarded field, play will not stop when the ball hits the boards and remains on the playing field. If a foul is called after the 7-minute horn or bell sounds, the Umpire’s whistle ends the period and the foul shall be awarded at the beginning of the next period.
(2) In the final period, if the game is not tied at the end of 7 minutes, the game will end on the 7-minute horn or bell.
(3) In the final regulation period and any subsequent overtime periods, if the game is tied play will continue until the second horn or bell, or until a goal is scored or awarded. If the play is stopped by the Umpires after the 7-minute horn or bell for any reason, the penalty, throw-in or free hit, as the case may be, shall be executed. If the play is stopped by the Umpire’s whistle after the 7-minute horn or bell for any reason, 5 seconds shall be allowed for execution of any penalty, free hit or bowl in, as the case may be.
