The inspection equipment required to perform the examination and tests prescribed herein is described in the Paragraph Reference/Inspection Method column in the tabl
39、es starting with 4.4.2.1. The contractor shall submit for approval inspection equipment designs in accordance with the-terms of the contract. See Section 6 of MIL-A-48078 and 6.3 of this specification. 4.5 Methods of insaection 4.5.1 Transportation vibration. The test shall be performed on complete
40、fuze assemblies (dwq. 9390425) in the unarmed position set SQ. The test shall be conducted in accordance with the procedures outlined in MIL-STD-331, Test 119, Procedure 2. Upon completion of the test, the fuzes shall not be disassembled but shall be x-rayed to determine if the fuze has armed, becom
41、e unsafe in any way, or has been damaged so as to not function. If so, that condition shall be classed as a test failure, and the ballistic sample shall not be fired. If the x-rays indicate the fuzes safe and operable, then they shall be assembled to 60MM, M302 rounds and fired at Charge O set SQ, a
42、s detailed in 4.5.4. 4.5.2 Lead assembly output test. The test shall be performed on the lead assembly (dwg. 9234683). A fixture shall be used to hold the lead assembly in central contact with the lead disc (dwg. 8816368). A ball (dwg. 8816014) shall be dropped a distance of five (5) inches onto a f
43、iring pin (dwg. 9200012) - distance is measured from the bottom of the ball to the top of the firing pin. The firing pin shall strike and initiate an M98 detonator (dwg. 9243921) which in turn will function the lead assembly. Observation shall be made for compliance with requirements as defined in 3
44、.6. Other suggested, but not mandatory, equipment which could be utilized in conjunction with this Set-up are: holder (dwg. 8816367) , bushing (dwg. 8827829) and base (dwg. 8802085). Government approval, of the test fixture to be used, is required. 4.5.3 Complete fuze leak test. This test shall be p
45、erformed on complete fuzes (dwg. 9390425). A fixture shall be used which covers the entire outer surface of the fuze with as little clearance as possible. The test shall be conducted at ambient temperature using 3 + 0.5 psi. Any sample which exhibits a pressure drop of more than 0.5 psi in 15 second
46、s minimum after stabilization shall be classed defective. A fixed volume of air shall be used so as to detect gross leaks. Equipment shall be as specified in 4.4.3. 14 t Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-F-70613 13 W 7977706 0356158
47、 O a MIL-F-70613 (AR) 4.5.4 Performance test (proving ground ballistic). 4.5.4.1 Functioning test. The sample fuzes shall be assembled to 60mm, M302, series cartridges and fired from an appropriate mortar between 450 and 750 elevation. If any fuze fails to aause the shell to function high order, tha
48、t fuze shall be classified as defective. If any fuze in either SQ or Delay setting mode causes the round to function prematurely, that fuze shall be classified as having critical defect. The proving ground shall utilize a geophonic sensing device to differentiate superquick and delay functionings at maximum charge. 4.5.4.1.1 SQ phase. The sample fuzes shall be divided into two (2) equal groups. The groups shall be fired at Charge O set SQ and maximum charge set SQ. 4.5.4.1.2 Delay phase. The sample fuzes shall be divided into two (2) equal groups. The groups shal
