The number in parenthesis denotes the number of cartridges allocated for each test. No cartridge shall produce results which fail to meet the requirements of 3.9.1 through 3.9
29、.3. Firings shall be conducted in the test fixture of 4.5.7. 4.3.3 Failure. Failure of any cartridge shall be cause for rejection of the first article sample. 4.4 Quality conformance inspection. Quality conformance inspection shall consist of the tests and examinations specified in table I and verif
30、ication of the characteristics classified on the drawings of DL491837. 4.4.1 Lot size. Unless otherwise specified (see 6.2), the production lot size shall be not less than 281 and not greater than 10,000.

37、s. 4.5.1 Smokeless powder, condition. Smokeless powder shall be inspected in accordance with the applicable paragraphs of OP 5. Evidence of decomposition shall be cause for rejection. 4.5.2 Visual examination. All cartridges shall be visually examined. Cartridges having any of the defects of 3.10 sh
38、all be cause for rejection. The preservation-packaging, packing, and marking of the cartridges shall be examined for conformance to section 5 and the contract (see 6.3). 4.5.3 Bridge circuit resistance. Conformance with the bridge circuit resistance of 3.8.1 shall be ascertained on all completely as
39、sembled cartridges by means of a test circuit which limits the bridge circuit current to 50 milliamperes, 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 oh
40、m in the range of resistance specified shall be used to determine whether or not the requirement is being met. Units which fail to meet the requirement of 3.8.1 shall be cause for rejection. The results of bridge circuit resistance measurements shall not be affected by resistance of the test circuit
41、 and connector. 4.5.4 Bridgewire circuit continuity. After soldering the bridgewire, the unloaded shell assembly (Drawing 1861735) shall be thoroughly cleaned to remove flux and contamination. After cleaning, the bridgewire shall be flashed with an electric current using a voltage source of 6 volts
42、ac or dc to produce a visible red glow of the bridge and ensure continuity. A suitable resistor may be used to regulate the current to the bridge. Flashing is a necessary manufacturing operation and shall be conducted on each loaded assembly. Assemblies with bridgewires which fail to glow shall be c
43、ause for rejection. Any faulty assemblies may be reworked by replacement of the bridges. 4.5.5 Unloaded shell assembly leakage. Apply not less than 10 psi of air pressure internally to all unloaded shell assemblies (Drawing 1861735) which have passed the continuity test of 4.5.4 and check for leaks.
44、 All assemblies that show evidence of leakage shall be cause for rejection. 4.5.6 Radiographic inspection. All cartridges shall be radiographically examined in accordance with ASTM E 545. Cartridges having any observable imperfections in assembly shall be cause for rejection. The cartridges shall be
45、 positioned on their sides for the most revealing exposure. All cartridges shall be identified with serial numbers prior to examination. The cartridge serial numbers shall be in consecutive numerical order beginning with the number 001 in each production lot. The cartridges shall be arranged on tray
46、s or boards in consecutive numerical order, and each radiograph shall carry a permanent identification of the cartridges displayed thereon. The radiograph identification shall include the complete lot number, as stamped on the cartridges, and the span of serial numbers displayed. Discontinuities in
47、serial numbers shall be identified on the N-ray. Defective cartridges found by the vendor shall be clearly identified on the N-ray and those defectives removed from the production lot. The serial numbers shall be pen or ink stamped on the cartridge with approximately 1/8-inch-high characters. The se
48、rial numbers shall be located apart from the other cartridge markings. 4.5.6.1 Sample radiographic plate. A sample radiographic plate and technique shall be submitted for n-ray by the contractor for approval prior to submitting radiographs for the production lot. The production lot radiographs shall
49、 be made using the identical technique utilized to produce the approved sample plate. Provided by IHSNot for ResaleNo reproduction or networking permitted without license from IHS-,-,-MIL-DTL-22244F (OS) 7 4.5.6.2 N-ray examination. Each cartridge shall be n-rayed in accordance with ASTM E 545, to confirm the presence of the propellant, non-metal parts, no foreign hydrogenous material and proper assemby of py
