13、ot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-605 19B 3.1 First article. When specified in the contract or purchase order (see 6.2), a sample shall be subjected to the first article inspection (see 4.4 and 6.3). 3.2 Materials. All materials used in the man
14、ufacture 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 methods of manufacture
15、are specified 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 intende
16、d for 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
17、pressure. The initiator chamber and cap shall withstand a hydrostatic pressure of 14,000 to 15,000 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 w
18、hen a load of 20 f 1 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
19、. Protective 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 directi
20、on using procedures in 4.6.5. 3.9 Workmanship. Initiators shall be free of 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, por
21、osity, or any similar defect. 3.9.2 Burr. No 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 forei
22、gn matter. 4. QUALITY ASSURANCE PROVISIONS 3 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-605 19B 4.1 Classification of inspections. The inspection requirements specified herein are classified as follows: a. First article inspection (see 4
23、.2) b. Conformance inspection (see 4.3). 4.1.2 Quality assurance terms and definitions. Reference shall be made to ASQC A804 to define the quality assurance terms used. 4.1.3 Inspections. Inspections shall be in accordance with MIL-A-2550. 4.1.4 Inspection conditions. Unless otherwise specified (see
24、 6.2), all inspections shall be performed under the following conditions: a. Temperature: room ambient (68 to 77EF) b. Altitude: sea level c. Humidity: 50 percent relative, maximum d. Atmospheric pressure: 14.7 psi 4.2 First article inspection. At the beginning of regular production, the contractor
25、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 fifty shear pins from the same lot of shea
26、r 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 packing, must be the same as will be used for regular production and sh
27、all 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 an acceptable sampl
28、e 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 ASQC 21.4. 4.5.1.2 Size of lot. The production lot size shall be as specifi
29、ed 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) magnification may be used in performing v
30、isual 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 measured or gaged to determine acceptabilit
31、y. All nonconforming material shall be rejected. 4 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-605 19B 4.5.2.1 Chamber, Initiator, Drawing 10520407, covering a detail of Drawing 10520621.
