For this event, the "A" standard qualification time was 1:00.59. Federations could enter one athlete into the event if they met the "B" standard qualification time. For this event, the "B" standard qualification time was 1:02.71. Athletes could also enter the event if they had met an "A" or "B" standard in a different event and their Federation had not entered anyone else.
