4.2.3.4.2 Retest. There shall be no retests.
4.2.3.4.3 Test failure. If a test failure is attributable to an assignable cause, excluding the test initiator, the original test results shall be discarded and that test reconducted.
4.3 Test methods and procedures.
4.3.1 Initiator pin security. A pull force shall be applied to the initiator pin in the longitudinal direction in conjunction with the applicable fixture which registers the amount of pull.
4.3.2 Breakawaytorque. Thetorquewrenchsetasspecifiedin3.5shallbeused inconjunction witha fixturetodeterminetheadequacyofthejoints. The chamber shall be secured in an air vise or holding fixture. The torque shall be applied to the cap.
4.3.3 Residual magnetism. The initiator shall be tested for excessive residual magnetism using an approved compass in an area free of local magnetic effects by placing the initiator 5 inchesfromtheend,and atthesameheightasthecompass,inthenorth-southhorizontal position (cap end at south) with the compass set in an east-west heading. The initiator shall be moved at a speed no greater than 10 feet per minute past the compass for its entire length, rotated 90 degrees in the horizontal position about its longitudinal axis, and moved slowly back past the compass. This procedure shall be repeated for each 90 degree rotation of the initiator.
4.3.4 Radiographic examination. Allassembled initiatorsshall beradiographically examined in accordance with MIL-STD-453, with the exception that an initiator assembly will be used for the penetrameter. Any observable imperfections in components or assembly shall be cause for rejection. The initiators shall be positioned for the most revealing exposure, with the long axis of each assembly perpendicular to the rays of the X-ray machine. All initiators shall be identified with serial numbers prior to X-ray examination. The serial numbers shall be in consecutiveorderbeginningwiththenumber001ineachproductionlot. Anymissingnumbersare to be identified on the X-rays. The initiators shall be arranged on trays or boards in consecutive numericalorder,andeachradiographshallcarryapermanentidentificationoftheunitsdisplayed thereon. Theradiographicplateidentificationshall includeitem nomenclature, the complete lot number, the span of serial numbers displayed, and the contract number. The radiographs of the entire production lot shall accompany the ballistic sample to the activity conducting the production lot acceptance test. Defective initiators found during X-ray review are to be marked ontheX-raypriortoshipmentandthosedefectiveitemsshallberemovedfromtheproductionlot. Film interpretation of the radiographs shall verify the presence and correct positioning of the following parts:
