15、roperties. Hardness and other physical properties required by the drawing shall be uniform throughout the part within specified tolerances. Requirements for all alloy steel parts shall be achieved by quenching and tempering. 3.4 Hydrostatic pressure. The body and head shall withstand a hydrostatic p
16、ressure of 7,500 pounds per square inch (psi) for 15 seconds, minimum, without leaking, deformation, or mechanical failure (see 6.4.1). 3.5 Shear pin strength. The shear pin, after application of protective finish, shall shear when a load of 48 f 4 pounds is applied at the steady rate of 0.125 inch
17、per minute. 3.6 Metal parts assembly. Parts shall be combined to produce an assembly which conforms to the requirements of the metal parts assembly drawing. All threaded joints shall be assembled handtight. 3.7 Protective finish. Protective finish shall be in accordance with the applicable specifica
18、tions and shall apply to all surfaces of the component regardless of contour configuration. 3.8 Residual magnetism. The metal parts assembly shall not deflect the indicator of the compass more than five degrees in either direction using procedures in 4.6.5. 3.9 Workmanship. Thrusters shall be free o
19、f cracks, splits, or other defects which might prevent proper mating with connecting parts or proper functioning of the device. 3.9.1 Metal defects. All components shall be free from cracks, splits, cold shuts, inclusions, porosity, or any similar defect. 3.9.2 Burr. No part shall have a burr which
20、might interfere with the assembly or function of the item or which might be injurious to personnel handling the item. 3.9.3 Foreign matter. No part or assembly shall contain chips, dirt, grease, rust, corrosion, or other foreign matter. 4. QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for inspecti
21、on. Unless otherwise specified in the contract or purchase order, the contractor is responsible for the performance of all inspection requirements (examinations and tests) as specified herein.

Unless otherwise specified (see 6.2), all inspections shall be performed under the following conditions: a
28、. Temperature: room ambient (68 to 77F) b. Altitude: sea level c. Humidity: 50 percent relative, maximum d. Atmospheric pressure: 14.7 psi 4.4 First article inspection. At the beginning of regular production, the contractor shall submit an initial production sample to a Government approved facility
29、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 fifty shear pins from the same lot of shear pins tested by the contractor. The sample shall be manufactured in the sam
30、e manner, using the same materials, equipment, processes, and procedures as used in regular production. All parts and materials, including packaging and packing, must be the same as will be used for regular production and shall be obtained from the same source of supply. After inspection and provisi
31、onal 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 article samples until an acceptable sample is submitted (see 6.3). 4.5 Quality conformance inspection. 4.5.1 Lot. 4.5
32、.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. The production lot size shall be as specified in the contract. 4.5.2 Examination. One hundred percent examination sha
