Select a testing method and imperfection type, then enter indication dimensions. The tool checks each API 1104 acceptance rule and cites the matching clause.
Test Setup
Indication Dimensions
Required IQI
Look up the essential wire, ASTM set letter, wire identity, or hole-type image quality indicator per the wall thickness and standard technique.
Hardness Limits
Table 12 maximum repair-weld hardness values (HV10) by process category and through-thickness location, with low-hydrogen 300 footnote applied when applicable.
Required Specimens
Table 7 minimum test specimen counts for welder qualification, broken down by pipe outside-diameter group and wall-thickness class.
Undercut Assessment
Table 8 / 9.7.2 acceptance standards for undercutting: the depth threshold is compared against both a fixed limit and a percent-of-wall fraction, with aggregate length checked in the intermediate tier.
Aggregate Length Check (required if depth falls in 1/64–1/32 in. band)
