Any indication that appears tobe superficial may be acceptable within the above lengthguidelines.3.3.1.1.4 Attached are drawings that show areas where noindications are permitted. (Appendix B)3.3.1.2 Any indications that appear to have depth (bright clear indication) orexceed the lengths noted above shall be ground. Grinding shall notexceed 1/16” in depth. After grinding the parts, they shall bereinspected. If the indication is still present after grinding (i.e.,exceeds 1/16” in depth), the part shall be deemed unacceptable.(See Section 3.3.1.3.)3.3.1.3 Unacceptable indications are circumferential indications orlongitudinal indications that are in excess of 1/16” in depth. Anyunacceptable indications (parts) that are found subjects the rest ofthe lot to MPI that is sufficient to detect all unacceptable parts inthat suspect lot.3.3.1.4 If the magnetic particle inspection indicates the presence of a subsurfacedefect, the part shall be sectioned and a determinationmade as to the source of the indication and the seriousness of itspresence with the assistance of SAF-HOLLAND Engineering ifnecessary.3.3.1.5 Magnetic Particle Inspection - Machine procedures:3.3.1.5.1 Magnetic particle inspection shall be performed inaccordance with ASTM-E-709 and A-275 using a wetfluorescent magnetic particle method.3.3.1.5.2 Magnetization shall be performed using the circularmagnetic field method first by clamping from end to endand then turning the forging 90° between the heads orby use of a multidirectional magnetization technique.3.3.1.6 All inspectors/operators shall be qualified to Level I, SNT-TC-1A orMIL-STD-410 minimum or CGSB 48.971-2000. All evaluations ofnonconformances shall be done by qualified Level II or Level IIInon-destructive testing personnel.3.3.1.7 Inspection results shall be recorded. Records must show the heatcode on the part, time of inspection, results (acceptable orunacceptable) and identification of the person performing theinspection.3.3.1.8 Parts that have been found acceptable in magnetic particleinspection shall be returned to their original lot or batch. They arenot to be mixed with another heat code or mill heat of material.
