MIL-I-602848
4.3.5 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:

4.3.6 Functional.
4.3.6.1 Ballistics. The test sample shall be rigidly supported in the fixture and fired by a source delivering an output of 700 +25,!0 psig at the end of 3 feet of aircraft hose, MS28741-4, at 70 ± 5EF. The sample shall be tested within 5 minutes after removal from the temperature conditioning chamber. When this time limit is exceeded, the sample units shall be reconditioned in accordance with 4.3.6.2. Required pressure readings shall be taken as specified in 3.6.1.
4.3.6.2 Temperature conditioning. Each assembled initiator shall be conditioned for not less than 4 hours nor greater than 24 hours. When reconditioning initiators at!60EF, all condensation shall be removed from the interior surfaces before returning the initiator to the conditioning chamber.
4.4 Inspection of packaging. The sampling and inspection of the packaging, packing, and container marking shall be in accordance with section 5.
