When specified (see 6.2), a sample shall be subjected to first article inspection (see 6.3) in accordance with see 4.4. 3.2 Materials. All ma
15、terials used in the manufacture of the initiators 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
16、methods of manufacture are specified on the drawings, the bidders selections shall be clearly stated in the proposal.

Hardness and other physical properties required by the drawing shall be uniform throughout t
18、he part within specified tolerances. Requirements for all alloy steel parts shall be achieved by quenching and tempering. 3.4 Hydrostatic pressure. The assembled female and male bodies of the initiator shall withstand a hydrostatic pressure of 14,000 to 15,000 pounds per square inch (psi) for 15 sec
19、onds, minimum, without deformation or mechanical failure (see 6.4.1). 3.5 Metal parts assembly. Parts shall be combined to produce an assembly conforming to the requirements of the metal parts assembly drawing. All threaded joints shall be assembled handtight. 3.6 Protective finish. Protective finis
20、h shall be in accordance with the applicable specifications and shall apply to all surfaces of the component regardless of contour configuration. 3.7 Residual magnetism. The metal parts assembly shall not deflect the indicator of the compass more than five degrees in either direction using procedure
21、s in 4.6.4. 3.8 Workmanship. The requirements for workmanship shall be as specified on the applicable drawings, referenced specifications, and the following: 3.8.1 Metal defects. All components shall be free from cracks, splits, cold shuts, inclusions, porosity, or any similar defect. 3.8.2 Burr. No
22、 part shall have a burr which might interfere with the assembly or function of the item or which might be injurious to personnel handling the item. 3.8.3 Foreign matter. No part or assembly shall contain chips, dirt, grease, rust, corrosion, or other foreign matter. 4. VERIFICATION 4.1 Classificatio

At the beginning 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 part
26、s assemblies, and nine sets of unassembled parts. The sample shall be manufactured in the same 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
27、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 article samples until su
28、ch time as 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 ASQ Z1.4. 4.5.1.2 Size of lot. The productio
29、n lot size shall be as specified in the contract (see 6.2). 4.5.2 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 b
30、e used for inspection of such defects as burr 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. All nonconforming material shall be rejected. 4.5.2.1 Body, Male,
