### Where the measured leakage exceeds the allowable, the leaking joints shall be located and corrected and the segment shall be retested until the leakage is within the allowable.
−### The allowable leakage formula recognizes that gasketed joints weep slightly under test, so the acceptance criterion is a calculated allowable rather than zero leakage; a visible leak at a single joint, however, shall be corrected regardless of the total measured leakage. {note}
