U.6.6 Flaw Acceptance Criteria
U.6.6.1 Acceptance Criteria Tables—Flaw dimensions resulting after the application of the rules of U.6.3, U.6.4,
and U.6.5 shall be evaluated for acceptance using the criteria of Table U.1a and Table U.1b.
U.6.6.2 Surface Examination—Flaws categorized as surface flaws during the UT examination may or may not be
surface-connected. Therefore, unless the UT data analysis confirms that the flaw is not surface-connected, a
supplemental surface examination (MT or PT) shall be performed in accordance with 8.2 or 8.4 as applicable for all
surface flaws. Any flaws which are detected by MT or PT and characterized as planar are unacceptable regardless of
length.
