17、duction or networking permitted without license from IHS-,-,-MIL-DTL-60517C 3When alternate materials or methods of manufacture are specified on the drawings, the bidders selections shall be clearly stated in the proposal. 3.2.1 Raw materials. The contractor shall be responsible for selecting from t
18、he classification list contained in the raw material specification the surface and physical condition of the raw material intended for use in manufacture. 3.3 Hardness and other physical properties. Physical properties required by the drawing shall be uniform throughout the part within specified tol
19、erances. Requirements for all alloy steel parts shall be achieved by quenching and tempering. 3.4 Hydrostatic 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 fai
20、lure (see 6.4.1). 3.5 Firing pin release.

The sample shall be manufactured in the same manner, usin
30、g 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 in regular production and shall be obtained from the same source of supply. After inspection and provisional acceptance
31、 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 such time as an acceptable sample is submitted (see 6.3). 4.5 Quality conformance inspection. 4.5.1 Lot. 4.5.1
32、.1 Submission of product. The product shall be submitted in accordance with ASQ Z1.4. 4.5.1.2 Size of lot. For the purpose of identification and shipment, the shipping lots of metal parts assemblies shall consist of 1200 assemblies, maximum, provided the homogeneity requirements of inspection lots h
33、ave been retained. 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 contained herein. Four power (4X) magnification may be used
34、 in performing visual examination for such defects as burr and foreign matter. Inspection for rubber O-rings shall be in accordance with ISO 3601-3. When compliance with the applicable requirements is in doubt as a result of visual examination, the characteristic shall be measured or gaged to determ
35、ine acceptability. All nonconforming material shall be rejected.
