18、ue application of 400 inch pounds, minimum, without any movement or deformation. 3.6 Structural strength. The assembled thruster shall withstand a static tensile force of 2,000 pounds, minimum, for 15 seconds, minimum, between mounting points without unlocking and without mechanical failure (see 6.4

19、.1). 3.7 Shear pin strength. The shear pin, after application of protective finish, shall shear when a load of 55 k 4 pounds is applied at the steady rate of 0.125 inch per minute. 3.8 Metal parts assembly. Parts shall be combined to produce an assembly which conforms to the requirements of the meta

20、l parts assembly drawing and the requirements of 3.8.1 through 3.8.3. 3.8.1 Head and body. The head and body shall be assembled hand tight. 3.8.2 Piston locking spring and end sleeve. The piston locking spring shall enter the spring hole in the piston without any bending along its entire length. The

21、 assembly of the piston locking spring to the end sleeve, with the cap screw and washer, shall be hand tight. If axial misalignment of the piston locking spring occurs upon completion of assembly, it will be permissible to back off the cap screw sufficiently to eliminate axial misalignment of the pi

22、ston locking spring. 3.8.3 End sleeve rotation. Upon completion of assembly and after the structural strength test, the end sleeve shall be free to rotate 360 degrees in a clockwise direction. 3.9 Protective finish. Protective finish shall be in accordance with the applicable specifications and shal

Unless otherwise specified in the contract or purchase order, the contractor is responsible for the performance of ail inspection requirements (examinations and tests)

27、as specified herein. Except as otherwise specified in the contract or purchase order, the contractor may use his own or any other facilities suitable for the performance of the inspection requirements specified herein, unless disapproved by the Government. The Government reserves the right to perfor

28、m any of the inspections set forth in this specification where such inspections are deemed necessary to ensure supplies and services conform to prescribed requirements (see 6.2). 4.1.1 Responsibility for compliance. All items shall meet all requirements of sections 3 and 5. The inspection set forth

29、in this specification shall become a part of the contractors overall inspection system or quality program. The absence of any inspection requirements in the specification shall not relieve the contractor of the responsibility of ensuring that all products or supplies submitted to the Government for

30、acceptance comply with ail requirements of the contract. Sampling inspection, as part of manufacturing operations, is an acceptable practice to ascertain conformance to requirements; however, this does not authorize submission of known defective material, either indicated or actual, nor does it comm

31、it 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. 4.2 Classification of inspections. The inspe

32、ction requirements specified herein are classified as follows: a. b. First article inspection (see 4.4) Quality conformance inspection (see 4.5) 4.3 Inspection conditions. Unless otherwise specified (see 6.2), all inspections shall be performed under the following conditions: a. Temperature: room am

33、bient (68 to 77F) b. Altitude: sea level c. Humidity: 50 percent relative, maximum d. Atmospheric pressure: 14.7 psi 4 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-T-46632B m 9999906 1985856 600 = 4.4 First article inspection. At the beginning

34、 of regular production, the contractor shall submit an initial production sample to a Government approved facility for evaluation. The sample shall consist of five metal parts assemblies, nine sets of unassembled parts, one set of unassembled parts without plating or final protective finish, and fif

35、ty shear pins from the same lot of shear pins tested by the contractor. The sample shall be manufactured in the same manner, using the same materiais, equipment, processes, and procedures as used in regular production. All parts and materials, including packaging and packing, must be the same as wil

36、l be used for regular production and shall be obtained from the same source of supply. After inspection and provisional acceptance at source, the first article sample shall be inspected for all requirements of the drawings and specifications. The Government reserves the right to require new first ar

37、ticle samples until an acceptable sample is submitted (see 6.3). 4.5 Quality conformance inspection. 4.5.1 Lot. 4.5.1.1 Submission of product. Unless otherwise specified by the contracting activity, formation and identification of lots shall be in accordance with MIL-STD-105. . 4.5.1.2 Size of lot.

38、The production lot size shall be as specified in the contract. 4.5.2 Examination. One hundred percent examination shall be performed for all critical defects. Examination for major and minor defects shall be performed on a defect basis in accordance with the classification of defects. Four power (4x

39、) magnification may be used in performing visual examination for such defects as burr and foreign matter. Inspection for rubber O-rings shall be in accordance with MIL-STD-413. When compliance with the applicable requirement is in doubt as a result of visual examination, the characteristic shall be

40、measured or gaged to determine acceptability. Ali nonconforming material shall be rejected. 4.5.2.1 Key, Drawing 8593857, covering a detail of Drawing 8593814.
