MIL-P-47158, MILITARY SPECIFICATION: PENETRANT INSPECTION, SOUNDNESS REQUIREMENTS FOR MATERIALS, PARTS AND WELDMENTS (07 JUN 1974) [S/S BY MIL-STD-1907]., This specification describes the defect limitsallowed under four quality level classifications for the penetrant inspection of forgings, castings, tubes, sheets, bars, etc.,(usually nonmagnetic 7 in the following fabrication stages:a. Unmachined or unwelded parts or materials.b. Machined parts.c. Weldments; for purposes of this specification, theterm Weldments refers to deposited filler metal andareas of base metal adjacent thereto which are likelyto be affected by the welding operation. Brazedjoints may also be considered as Weldments under thisspecification.
