Prior to installation of the bridgewire, the insulation resistance between pins and case shall not be less than 2 megohms at a relative humidity of less than 80 percent when measured with a
18、500-volt megohmmeter (see 4.5.1). 3.6 Bridgewire. The bridgewire shall be welded to the pins. 3.7 Bridgewire continuity. Before filling the cavity around the bridges with the igniter compound, the bridge assemblies shall be thoroughly cleaned and inspected for proper attachment and absence of projec
19、ting ends. After cleaning, the bridgewire shall be flashed by application of an electric current to assure continuity of both bridgewires. The current shall be regulated to produce a visible red glow of the bridges. An electromagnetic force (EMF) of approximately 1.5 volts ac or dc may be used with
20、a suitable series resistor to adapt the source characteristics to the primer resistance. Flashing is a necessary manufacturing operation and shall be conducted on each bridgewire assembly. Assemblies which fail to glow in both bridges shall be screened fiom acceptable material in the process. The di
21、scarded assemblies may be reworked by replacement of the bridges. 3.8 Primer mix. The primer mix shall be compounded as specified on Drawing 2406487. 3.9 Loading of igniter composition. The techniques of loading the igniter composition shall be such as to avoid damage to the bridgewire. The composit
22、ion shall be smoothed off flush with the top of the caviy. All igniter composition shall be removed from exterior lateral areas of the spacer. Allow to dry thoroughiy before cementing mylar disc in place. The dried Composition shall be free from cracks, voids, and separation fiom the ignition cup. T
23、he charge shall entirely cover the bridgewire. 3.10 Propellant charge. 3.10.1 Quantity. All propellant charges shall be determined by weight rather than by volume measurement. 3.10.2 Smokeless powder: handling, and loading. The smokeless powder shall be subjected to no unnecessary handling or exposu
24、re to the atmosphere. The handling and loading of smokeless powder Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-2366 lB(0S) exposed to the atmosphere shall be performed only under conditions that do not permit the relative humidity to exce
25、ed 75 percent. 3.10.3 Smokeless powder, condition. The smokeless powder used shall exhibit no evidence of decomposition (see 4.5.2). 3.11 Cartridge inspection. 3.1 1.1 Bridgewire resistance.

There shall be no misfires (see 4.5.6.1). 3.12.3 Hangfire. There shall be no hangfires (see 4.5.6.2). 3.13 Workmanship. Cartridges shall be free of the
28、following defects: burrs, dents, incomplete or damaged threads, improper crimp, perforated closure disc, bent pins, or other defects which may prevent entry of the cartridge into the firing chamber, or affect resistance of the cartridge to moisture. All cartridge marking and identification shall be
29、verified as proper (see 4.5.3). 4. VERIFICATION 4.1 Classification of inspections. a. First article inspection (see 4.3) b. Quality conformance inspection (see 4.4) 4.2 Inspection conditions. Unless otherwise specified, all inspections shall be performed in accordance with the test conditions specif
30、ied in 4.5. 4.3 First article inspection. First article inspection shall be performed after award of contract and prior tu production by a facility designated in the contract or order (see 6.2). A first article sample acceptable for environmental and hction testing shall be considered a sample which
31、 has met the requirements of 3.2 through 3.1 1.2 and 3.13. First article inspection shall be performed on sample units which have been produced using the same materials, equipment, processes, and procedures as will be used in regular production. All parts and materials, including packaging and packi
32、ng shall be the same as used for regular production and shall be from the same sources of supply. 4.3.1 Sample size. The first article sample shall consist of 60 cartridges plus retain samples. 4 Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DT
33、L-2366 1 B(0S) Cartridge 4.3.2 Inspection routine.

Testing shall consist of the following tests as prescribed in MIL-D-21625: 15 “g”
34、shock (6); vibration (6); temperature and humidity cycling (12). After environmental treatment, these cartridges are to be conditioned together with 12 untreated cartridges, at 70F and fired as specified in 4.5.6. In addition 12 cartridges each shall be conditioned at -65F and 160F and fired as spec
35、ified in 4.5.6 to check temperature sensitiviy. Acceptance of the 70F firings shall be in accordance with 4.5.6. Preservation-packaging, Section 5, 4.5.3 (MI03) packing, and marking Contract 4.3.3 Failure. Failure of any cartridge shall be cause for rejection of the first article sample. 4.4 Quality
36、 conformance inspection. Quality conformance inspection shall consist of the tests and examinations specified in table I. 4.4.1 Lot size. Unless otherwise specified (see 6.2), the production lot size shall be not less than 11 1 and not greater than 500. Only primary components from a single lot shal
37、l be used in a production lot of cartridges; however, one primary component lot may be used in more than one cartridge production lot. 4.4.2 Sampling. Unless otherwise specified (see 6.2), sampling shall be in accordance with table II. 4.4.3 Ciassification of characteristics. The characteristics ver
38、ified by the tests and examinations herein are classified as Critical, Major or Minor in accordance with DOD-STD-2 1 O 1. Tests and esaminations that veri critical Characteristics are identified by the symbol (C) and major characteristics by the symbol (M). The number following the classification sy
39、mbol indicates the serial number of test or examination.

Prior to assembly of
41、 the bridgewire in the body and spacer assembly, the insulation resistance shall be checked with a 500-volt megohmmeter. Units with a resistance of less than 2 megohms shall be cause for rejection. 4.5.2 Smokeless powder, condition. Smokeless powder shall be inspected in accordance with the applicab
42、le paragraphs of OP 5. Evidence of decomposition shall be cause for rejection. 4.5.3 Visual examination. All cartridges shall be visually esamined. Cartridges having any of the defects of 3.11.3 shall be cause for rejection. The preservation-packaging, packing, and marking of the cartridges shall be
43、 examined for conformance to section 5 and the contract (see 6.5). 4.5.4 Bridgewire resistance. Conformance with the bridgewire circuit resistance of 3.11.1 shall be ascertained on all completely assembled cartridges by means of a test circuit which limits the bridge circuit current to 50 milliamper
44、es, maximum. A safety chamber with an interlock switch shall be used to protect the operator during the application of current. A suitable instrument which is known to be accurate to within 0.005 ohm in the range of resistance specified shall be used to determine whether or not the requirement is be
45、ing met. Units which fail to meet the requirement of 3.1 1.1 shall be cause for rejection.
