Rules and Regulation


SW 11.1 The operation of Automatic Officiating Equipment shall be under the supervision of appointed officials. Times recorded by Automatic Equipment shall be used to determine the winner, all placing and the time applicable to each lane. The placing and times so determined shall have precedence over the decisions of timekeepers. In the event that a break-down of the Automatic Equipment occurs or that it is clearly indicated that there has been a failure of the Equipment, or that a swimmer has failed to activate the Equipment, the recordings of the timekeepers shall be official (See SW 13.3). 

SW 11.2 When Automatic Equipment is used, the results shall be recorded only to 1/100 of a second. When timing to 1/1000 of a second is available, the third digit shall not be recorded or used to determine time or placement. In the event of equal times, all swimmers who have recorded the same time at 1/100 of a second shall be accorded the same placing. Times displayed on the electronic scoreboard should show only to 1/100 of a second.

SW 11.3 Any timing device that is terminated by an official shall be considered a watch. Such manual times must be taken by three timekeepers appointed or approved by the Member in the country concerned. All watches shall be certified as accurate to the satisfaction of the governing body concerned. Manual timing shall be registered to 1/100 of a second. Where no Automatic Equipment is used, official manual times shall be determined as follows:

SW 11.3.1 If two (2) of the three (3) watches record the same time and the third disagrees, the two identical times shall be the official time.

SW 11.3.2 If all three (3) watches disagree, the watch recording the intermediate time shall be the official time.

SW 11.3.3 With only two (2) out of three (3) watches working the average time shall be the official time.

SW 11.4 Should a swimmer be disqualified during or following an event, such disqualification should be recorded in the official results, but no time or place shall be recorded or announced.

SW 11.5 In the case of a relay disqualification, legal splits up to the time of the disqualification shall be recorded in the official results.

SW 11.6 All 50 metre and 100 metre splits shall be recorded for lead-off swimmers during relays and published in the official results.
