17、 unless a specific exemption has been obtained. 3. REQUIREMENTS 3.1 Materials. All materials used in the manufacture of the initiators shall conform strictly to the specifications referred to on the respective drawings unless specific approval in writing covering a departure therefrom has been obtai
18、ned 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 clearly stated in the proposal. 3.2 Primary components. For the purpose of this specification, the M91 delay cartridge (
19、Drawing 8597230) is defined as a primary component. Only primary components from a single lot shall be used in a production lot of initiators. One primary component production lot may be used in more than one initiator production lot. 3.3 Breakaway torque. The chamber and cap of the assembled initia
20、tor shall withstand a breakaway torque application of 400 inch pounds without loosening or deformation (see 4.2.3.1). 3.4 Residual magnetism. The initiator shall not deflect the indicator of the compass more than five degrees in either direction using procedure 4.2.3.2. 3.5 Firing pin release. The f
21、iring pin of the assembled initiator, less safety pin, cartridge and chamber shall release from the cocked position when the application of an axial load of 18 to 25 pounds has withdrawn the initiator pin 0.370 inch, minimum, and 0.425 inch, maximum (see 4.2.3.3). 3.6 Initiator pin security. Applica
22、tion of an axial load of 200 to 220 pounds to the initiator pin of the assembled initiator shall not withdraw the initiator pin past the safety pin. Load application shall cause no permanent deformation of the safety pin (see 4.2.3.4). 3.7 Functional (see 4.2.3.5). 3.7.1 Ballistics. Initiators loade

All components shall be free from cracks, splits, cold shuts, inclusions, porosity, or any similar defect. 3.8.2 Burr. No part shall have a burr which might interfere with the assembly or functi
27、on 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. 3.9 Radiographic examination. Each initiator assembly shall be radiographically examined for defects as sp
28、ecified in 4.4. 3.10 Component parts. All component parts shall meet the requirements of MIL-I-60525 or MIL-I-82767 prior to assembly. 4. VERIFICATION 4.1 Quality assurance terms and definitions. Reference shall be made to ASQ A8402 to define the quality assurance terms used. 4.1.1 Inspection. Inspe
29、ction shall be in accordance with MIL-A-2550. 4.2 Inspection provisions. 4.2.1 Lot. 4.2.1.1 Submission of product. Unless otherwise specified by the contracting officer, formation of lots and presentation of lots shall be in accordance with the “Submission of Product“ provisions of ASQ Z1.4. 4.2.1.2
30、 Size of lot. A lot shall consist of an identifiable group of assembled initiators containing metal parts assemblies produced by a homogeneous process and loaded with one lot of accepted cartridges. 4.2.2 Examination. One-hundred percent examination shall be performed for all critical defects. Exami
31、nation for major and minor defects shall be performed in accordance with the classification of defects. Four power (4X) magnification may be 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,
32、the characteristic shall be measured or gaged to determine acceptability. All nonconforming material shall be rejected.

The Following tests shall be performed in accordance with the provisions of 4.3. 4.2.3.1 Breakaway torque. Each assembly shall be subjected to the breakaway torque test of the threaded joint
44、between the cap and the chamber. Failure of any assembly to comply with the requirements of 3.3 shall be cause for rejection of the initiator. 4.2.3.2 Residual magnetism. Each initiator shall be subjected to the test for excessive residual magnetism as specified in 4.3.2. Failure of any initiator to
45、 comply with the requirement of 3.4 shall be cause for rejection of the initiator. 4.2.3.3 Firing pin release. The initiator pin of each subassembly, consisting of all parts, except the safety pin, cartridge, and chamber, shall be subjected to the firing-pin release test. Failure of any subassembly
46、to comply with the requirements of 3.5 shall be cause for rejection of the subassembly.
