For the purpose of this specification, the PVU-1/A Ignition Device, Delay Cha
20、rge and the output material charge are considered primary components. Only primary components from a single lot shall be used in a production lot of cartridges; however, one primary component production lot may be used in more than one cartridge production lot (see 6.7). 3.4.1.1 Ignition device. The
21、 ignition device shall be furnished from lots manufactured within the preceding 24 months or recertified within the preceding 12 months. The ignition device shall be manufactured per Drawing 851AS110 and accepted per WS 21535. Prior to assembly into a delay element, the ignition device shall be visu
22、ally examined in accordance with 4.6.5 and radiographically examined for defects as specified in 4.7.1. 3.4.2 Protective finish. The finish of each component part shall be in accordance with MIL-A-8625 and the applicable drawing (see 4.7.2). 3.5 Assembly. 3.5.1 Radiographic examination. Each delay e
23、lement assembly shall be radiographically examined for defects (see 4.7.3). 3.5.2 Vibration. 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 ignition device, prope
24、llant, or igniter, or derangement of any component (see 4.7.4 and 6.2). 3.6 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 M
25、IL-B-550, and boron, as specified in MIL-B-51092, in the proportion and quantity fixed by the contractor to produce the ignition delay times required in table I (see 6.6.1).

At the beginning of regular production, the supplier shall submit a first article sample to a Government approved facility for evaluation. The sample shall consist of 23 delay bodies, 23 ignition device retainers to b
32、e 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 manufactured using the same materials, equipment, processes, and procedures as used in regular production. All parts and
33、 materials, including packaging and packing, shall be the same as used for regular production and shall be obtained from the same source of supply.
