When specified in the contract or purchase order (see 6.2), a sample shall be subjected to first article inspection (see 4.4 and 6.3). 3.2 Materials. All materials used in the manufacture of th
18、e initiators shall conform strictly 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 manufacture are s
19、pecified on the drawings, the bidders selections shall be clearly stated in the proposal. 3.2.1 Raw Material. The contractor shall be responsible for selecting from the classification list contained in the raw material specification the surface and physical condition of the raw material intended for
20、 use in manufacture. 3.3 Hardness and other physical properties. 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 press
21、ure. The initiator chamber and cap shall withstand a hydrostatic pressure of 5500 to 6500 pounds per square inch (psi) for 15 seconds, minimum, without 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 loa
22、d of 41 5 pounds is applied at the steady rate of 0.125 inch 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. Protectiv
23、e finish shall be in accordance with the applicable specifications 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 p
24、rocedures in 4.6.5. 3.9 Workmanship. The requirements for workmanship are as specified on the applicable drawings, referenced specifications and the following: 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. N
25、o 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. 3.9.3 Foreign matter. No part or assembly shall contain chips, dirt, grease, rust, corrosion or other foreign matter. Source: http:/assist.daps.dla.mil

VERIFICATION 4.1 Classification of Inspections. The inspection requirements spe
27、cified herein are classified as follows: a. First article inspection (see 4.4) b. Quality conformance inspection (see 4.5). 4.1.1 Quality assurance terms and definitions. Reference shall be made to ANSI/ASQ A8402 to define the quality assurance terms used. 4.1.2 Inspection. Inspection shall be in ac
28、cordance with MIL-A-2550. 4.3 Inspection conditions. Unless otherwise specified (see 6.2), all inspections shall be performed under the following conditions: a. Temperature: Room ambient 68 to 77 F b. Altitude: Sea level c. Humidity: 50 percent relative, maximum d. Atmospheric pressure: 14.7 psia 4.
29、4 First article inspection. 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 5 metal parts assemblies, 9 sets of unassembled parts, 1 set of unassembled parts without plating
30、 or final protective finish and 50 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 materials, equipment, processes and procedures as used in regular production. All parts and materials, including packaging and p
31、acking, must be the same as will 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 th
32、e right to require new first article samples until such 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 accordan
33、ce with ANSI/ASQ Z1.4. 4.5.1.2 Size of lot. For the purpose of identif ication and shipment, the shipping lots of metal parts assemblies shall consist of 600 assemblies, maximum, provided the homogeneity requirements of inspection lots have been retained. 4.5.2 Examination. One-hundred percent exami
34、nation 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 (4) magnification may be used in performing visual examination for such defects as burr and foreign matter. In
35、spection 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 he measured or gaged to determine acceptability. All nonconforming material shall be rejected. Source: http:/as
