Nothing in this document, however, supersedes applicable laws and regulations unless a specific exemption has been obtained. 3. REQUIREMENTS 3.1 Materials. Ail materials u
14、sed in the manufacture of the thrusters shall conform to the specifications referred to on the respective drawings unless specific approval in writing covering a departure therefrom has been obtained from the cognizant Navy design activity prior to manufacture. When alternate materials or methods of
15、 manufacture are specified on the drawings, the bidders selections shall be clearly stated in the proposal. 3.2 Components. 3.2.1 Primary components. For the purpose of this specification, the M44A1 impulse cartridge (Drawing 8593276) is defined as a primary component. Only primary components from a
16、 single lot shall be used in a production lot of thrusters; however, one primary component production lot may be used in more than one thruster production lot. 3.2.2 Component parts. Ail component parts shall meet the applicable requirements of MIL-T- 46583 or MIL-T-60697 prior to assembly. 3.3 Torq
17、ue. Torque requirements shall be as specified in table I. No movement shall occur upon application of the breakaway torque. TABLE I. Toraue reauirements. 3.4 Trunnion rotation. Upon completion of assembly, the trunnion shall be free to rotate 360 degrees. 3.5 Residual magnetism. The thruster shall n
18、ot deflect the indicator of the compass more than five degrees in either direction (see 4.3.2). 3 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-T-VbbLbC D 9999906 LV8895L however, this does not authorize submission of known defective material,
19、either indicated or actual, nor does it commit the Government to acceptance of defective material. 4.1.2 Quality assurance terms and definitions. Reference shall be made to MIL-STD-109 to define the quality assurance terms used. 4.1.3 Inspections. Inspections shall be in accordance with MIL-A-2550 a

21、ct (see 6.2). 4.2.2 Examination. One hundred percent examination shall be performed for all critical defects. Examination for major and minor defects shall be performed in accordance with the classification of defects. Four power (4x) magnification may be used for inspection of such defects as burr
22、and foreign matter. When compliance with the applicable requirement is in doubt as a result of visual examination, the characteristic shall be measured or gaged to determine acceptability.

Failure of any subassembly to comply with the requirements of column C, table I in 3.3 shall be cause for rejection of the subassembly. 4.2.3.1.2 Cartridge retainer and breech. Each cartridge retainer
37、and breech subassembly shall be subjected to a breakaway torque. Failure of any subassembly to comply with the requirements of column C, table I in 3.3 shall be cause for rejection of the subassembly. 4.2.3.1.3 Body and breech.

A torque wrench, set at the torque requirements specified in table I, shall be used with an appropriate adapter to determine the adequacy of the joints. The cartri
43、dge retainer shall be held secure and the torque shall be applied to the breech. The thruster body shall be held secured and the torque shall be applied to the breech and end cap. 4.3.2 Residual magnetism. The assembly shall be tested for excessive residual magnetism using an approved compass in an
44、area free of local magnetic effzcs by placing the assembly 5 inches from the end at the same height as the compass, in the north-south horizontal position (head end at south) with the compass set in an east-west heading. The assembly shall be moved at a speed no greater than 10 feet per minute past
45、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 assembly for four full passes. 4.3.3 Radiographic examination. All assembled thrus
46、ters shall be radiographically examined in accordance with MIL-STD-453, with the exception that an thruster assembly will be used for the penetrameter. Any observable imperfections in components or assembly shall be cause for rejection. The thrusters shall be positioned for the most revealing exposu
47、re, with the long axis of each assembly perpendicular to the rays of the X-ray machine. All thrusters shall be identified with serial numbers prior to X-ray examination. The serial numbers shall be in consecutive order beginning with the number O01 in each production lot. Any missing numbers are to
48、be identified on the X-rays. The thrusters shall be arranged on trays or boards in consecutive numerical order, and each radiograph shall carry a permanent identification of the units displayed thereon. The radiographic plate identification shall include item nomenclature, the complete lot number, t
49、he 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 thrusters found during X-ray review are to be marked on the X-ray prior to shipment and those defective items shall be removed from the production lot.
