HFS-03 – SAF-HOLLAND Lock Standard Page 10 of 35Rev. K (6/11)4.2.1 Macro-etch grain flow(Procedure applies only to XE-09416, XE-07296 and XE-10487.)4.2.1.1 Cut the lock forging to produce a 1/4” - 1/2” thick section exposingthe center of the lock. (Appendix C)4.2.1.2 The section will be ground smooth and etched in 50% HCl, 50% H 2 0heated to 160-180°F to show the grain flow of the material. Grainflow shall be as shown in Appendix C. Radii areas will be examinedfor any defects.4.2.1.3 Results shall be evaluated, photographed, and documented on theLock Test Report Report Form, Appendix D.4.2.2 Magnetic Particle Inspection4.2.2.1 The sections of the lock remaining from the grain flow sectioningshall be inspected by magnetic particle method for indications.4.2.2.2 The magnetic particle machine shall be set up in accordance withSection 3.3.1.5 of this procedure.4.2.2.3 The forged surface areas shall be evaluated in accordance withSection 3.3.1.1 through 3.3.1.4. Results shall be recorded on theLock Test Report Form (Appendix D).4.3 A copy of the Lock Test Report shall be sent to Receiving noting if the parts areacceptable or unacceptable. Appropriate action shall be taken in accordance withstandard quality assurance procedures.4.4 Cause for rejection of a heat of locks at Receiving shall include:4.4.1 Unacceptable magnetic particle results4.4.2 Improper or irregular grain flow4.4.3 Visual defects in the grain flow indicated in Appendix C4.5 Action in the event of rejection of locks:4.5.1 The entire batch (heat) of locks shall be placed on “Hold”.4.5.2 All results shall be reviewed by SAF-HOLLAND Engineering for disposition.4.6 Lot control of the forgings and finished parts shall be maintained by part number andheat code at all phases of production and inventory.5.0 Dimensional Control
HFS-03 – SAF-HOLLAND Lock Standard Page 11 of 35Rev. K (6/11)5.1 Dimensions specified on the Engineering drawings (XA-07296-1 and XA-09416) asCC-2 will be controlled using statistical process control techniques.6.0 SAF-HOLLAND Test Plan Procedure - SAF-HOLLAND In-Process6.1 All testing shall be performed following heat treating.6.2 Brinell Hardness:6.2.1 The Brinell hardness shall be taken on each lock after heat treat. This is a100% inspection.6.2.2 The test results records shall show the following:• SAF-HOLLAND part number• Heat code number• Work order number (if applicable)• Date• Operator• Hardness6.2.3 Records shall be maintained on file by part number for 15 years minimum.6.3 Magnetic Particle Inspection:6.3.1 Magnetic particle inspection shall be conducted per ASTM-E-709 and A-275.6.3.1.1 M.P.I. Machine Procedures (See Section 3.3.1.5)6.3.1.2 The magnetic particle machine shall be calibrated at regularscheduled intervals.6.3.1.3 The fluorescent particle bath shall be circulated a minimum of 30minutes prior to inspection.6.3.1.4 The fluorescent particle bath shall be checked daily prior to use.The particle level shall be maintained per ASTM-E-709recommended levels.6.3.1.5 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.6.3.2 The Standard SAF-HOLLAND Inspection Procedure is detailed on theMagnetic Particle Technique Sheet (HFS-03/MT-01) and shall be used for alllock inspection unless otherwise specified on the applicable SAF-HOLLANDdrawing.6.3.3 Magnetic particle inspection shall be done on a sampling plan as follows:
