When specified in the contract or purchase order (see
13、6.2), a sample shall be subjected to first article inspection (see 4.4 and 6.4). 3.2 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 therefr
14、om 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 clearly stated in the proposal. 3.3 Raw material. The contractor shall be responsible for selecting fro

Physical properties required by the drawing shall be uniform throughout the part within specified tolerances. Require
16、ments for all alloy steel parts shall be achieved by quenching and tempering. 36 Hydrostatic pressure. 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 65.1). 3.6
17、Shear pin strength. The shear pin, after application of protective finish, shall shear when a load of 41 f 5 pounds is applied at the steady rate of 0.125 inch per minute. 2 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-I-6050BA 23 W 7779706 03

All threaded joints shall be assembled handtight. to all surfaces of the component regardless of contour configuration. five degrees in either direction using procedures in 4.6.5. / 3.10 Workmanship. The requireme
20、nts 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 might interfer
21、e with the assembly or function of the item or which might be injurious-to personnel handling the item. 3.10.3 Foreign matter. No part or assembly shall contain chips, dirt, grease, rust, corrosion or other foreign matter. 4. QUALITY ASSURANCE PROVISIONS 4.1 Responsibility for inspection. Unless oth

24、conform to prescribed requirements. 4.1.1 Responsibility for compliance. All items shall meet all requirements of sections 3 and 5. The inspection set forth in this specification shall become a part of the contractors overall inspection system or quality program. The absence of any inspection requir
25、ements in the specification shall not relieve the contractor of the responsibility of ensuring that all products or supplies submitted to the Government for acceptance comply with all requirements of the contract. Sampling inspection, as part of manufacturing operations, is an acceptable practice to
26、 ascertain conformance to requirements; however, this does not authorize submission of known defective material, either indicated or actual, nor does it commit the Government to accept defective material. 4.1.2 Quality assurance terms and definitions.

30、consist of 5 metal parts assemblies, 9 sets of unassembled parts, 1 set of unassembled parts without plating 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
31、, 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 shall be obtained from the same source of supply. After inspection and provisional acceptance at source, the first article s
32、ample 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 6.4). 4.5 Quality conformance inspection. 4.5.1 Lot. 4.5.1.1 Submission of product.
