16、L-60525B 3 3. REQUIREMENTS 3.1 First article. 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 the initiators shall conform strictly to the specifications ref
17、erred 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 specified on the drawings, the bidders selections shall be cle
18、arly 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 use in manufacture. 3.3 Hardness and other physical properti
19、es. 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 initiator chamber and cap shall withstand a hydrostatic pressure of 14,
20、000 to 15,000 pounds per square inch (psi) for 15 seconds, minimum, without deformation or mechanical failure (see 6.4.1). 3.5 Firing pin release. The firing pin of the metal parts assembly, less safety pin, shall release from the cocked position when the application of an axial load of 18 to 25 pou
21、nds has withdrawn the initiator pin 0.370 inch, minimum, and 0.425 inch, maximum. 3.6 Initiator pin security. Application of an axial load of 200 to 220 pounds to the initiator pin of the metal parts assembly shall not withdraw the initiator pin past the safety pin. Load application shall cause no p
22、ermanent deformation of the safety pin. 3.7 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. 3.8 Protective finish. Protective finish shall be in accordance w
23、ith the applicable specifications and shall apply to all surfaces of the component regardless of contour configuration. 3.9 Residual magnetism. The metal parts assembly shall not deflect the indicator of the compass more than 5 degrees in either direction using procedures in 4.6.6. 3.10 Workmanship.
24、 The requirements for workmanship are as specified on the applicable drawings, referenced specifications and the following: 3.10.1 Metal defects. All components shall be free from cracks, splits, cold shuts, inclusions, porosity or any similar defect. 3.10.2 Burr. No part shall have a burr which mig
25、ht interfere with the assembly or function of the item or which might be injurious to personnel handling the item. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-60525B 4 3.10.3 Foreign matter. No part or assembly shall contain chips, dirt,
26、grease, rust, corrosion or other foreign matter. 4. VERIFICATION 4.1 Quality assurance terms and definitions. Reference shall be made to ASQ A8402 to define the quality assurance terms used. 4.1.2 Inspection. Inspection shall be in accordance with MIL-A-2550. 4.2 Classification of Inspections. The i
27、nspection requirements specified herein are classified as follows: a. First article inspection (see 4.4) b. Quality conformance inspection (see 4.5). 4.3 Inspection conditions. Unless otherwise specified, all inspections shall be performed under the following conditions: a. Temperature: Room ambient
28、 20 to 25 C (68 to 77 F) b. Altitude: Sea level c. Humidity: 50 percent relative, maximum. d. Atmospheric pressure: 14.7 psia 4.4 First article inspection. At the beginning of regular production, the contractor shall submit a first article sample to a Government approved facility for evaluation. The
29、 sample shall consist of 5 metal parts assemblies, 9 sets of unassembled parts, and 1 set of unassembled parts without plating or final protective finish. The sample shall be manufactured in the same manner, using the same materials, equipment, processes, and procedures as used in regular production
30、. 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 provisional acceptance at source, the first article sample shall be inspected for all requirements of the dra
31、wings 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. 4.5.1.1 Submission of product. The product shall be submitted in accordance with ASQ Z1.4. 4
32、.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 have been retained. 4.5.2 Examination. One-hundred percent examination shall be performe
33、d for all critical defects. Examination for major and minor defects shall be performed. Four power (4X) magnification may be used 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 t
34、he 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.
