The assembled delay element shall withstand vibration as prescribed in MIL-STD-810, Method 514.3, Test Procedure I, Test Condition 1-3.2.5 without evidence of any disintegration of the primer, propellant, or igniter, or derangement of any component (see 4.7.4 and 6.2). 3.6
19、Functional requirements. 3.6.1 Delay element performance. 3.6.1.1 Misfires. The ignition delay element shall not fail to fire. 3.6.1.2 Ballistics. The ignition delay charge shall consist of barium chromate, as specified in MIL-B-550, and boron, as specified in MIL-B-51092, in the proportion and quan
20、tity fixed by the contractor to produce the ignition delay times required in table I (see 6.6. i). 3.7 Workmanship. Delay elements shall be free of cracks, splits, or other defects which might prevent proper mating with connecting parts or proper functioning of the device. 3 Provided by IHSNot for R

No part or assembly shall contain chips, dirt, grease, rust, corrosion, or other foreign matter. 4. QUALITY ASSUR
23、ANCE PROVISIONS 4.1 Responsibility for inspection. Unless otherwise specified in the contract or purchase order, the contractor is responsible for the performance of all inspection requirements (examinations and tests) as specified herein. Except as otherwise specified in the contract or purchase or
24、der, the contractor may use his own or any other facilities suitable for the performance of the inspection requirements specified herein, unless disapproved by the Government. The Government reserves the right to perform any of the inspections set forth in this specification where such inspections a
25、re deemed necessary to ensure supplies and services conform to prescribed requirements (see 6.2). 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 s
26、ystem or quality program. The absence of any inspection requirements 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
27、part of manufacturing operations, is an acceptable practice to 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
28、 definitions. Reference shall be made to MIL-STD-109 to define the quality assurance terms used. 4.1.3 Inspections. Inspections shall be in accordance with MIL-A-2550 and MIL-STD-453. 4 O Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-f a MIL-D-4bbO

At the beginning of regular production, the contractor shall submit a first article sample to a Government approved
32、facility for evaluation. The sample shall consist of 23 delay bodies, 23 primer retainers, 21 units for ballistics, to be tested as indicated in table II, and 10 sets of unassembled components (including explosive components) for visual and dimensional examination. The first article sample shall be
33、manufactured using the same materials, equipment, processes, and procedures as used in regular production. All parts and materials, including packaging and packing, shall be the same as used for regular production and shall be obtained from the same source of supply. When it becomes necessary to mak
34、e a change in either the primer, propellant, or igniter lot after initial production, 12 assembled delay elements from the first production lot thereafter shall be tested in accordance with 4.7.5. The Government reserves the right to require new first article samples until such time as an acceptable
35、 sample is submitted (see 6.3). TABLE II; First article inspection. 44.1 Examination, tests, and facility, After provisional acceptance at source, the sample shall be inspected for all requirements of the drawings and specifications at a Government laboratory or other such facility specified in the

39、nd components shall be examined visually and radiographically and characteristics defined in accordance with the applicable drawings. One hundred percent examination shall be performed for all critical defects. Examination for major or minor defects shall be performed on a defect basis in accordance
40、 with the classification of defects. Four power (4X) magnification may be used in performing visual examination for such*defects as burrs and foreign matter. When compliance is in doubt as a result of visual inspection, the characteristic shall be measured or gaged to determine acceptability. All no
