"From 2000, IAAF Rule 260.18s (formerly 260.6.a) was amended to say world records (as opposed to indoor world records) can be set in a facility 'with or without a roof.' So far, only one event - the women's pole vault - has been affected by this change, which was not applied retrospectively." [1] (p.546) 세르히 부브카 set an indoor record of 6.15 m on February 21, 1993, in excess of the outdoor record, before this rule came into effect.
