MIL-DTL-82884A
4.5.4 Visual examination. All cartridges shall be visually examined. Those having any of the defects specified
in 3.7 shall be rejected.
4.5.5 Leakage. Each cartridge in the first article sample and production lot sample shall be leak tested in a dry
gas leak tester. Cartridges which exhibit a leak rate in excess of 10-5 cm3 per second of air at a pressure
differential of 1.0 ± 0.1 atmosphere shall be considered defective. Defective cartridges of the first article sample
shall be rejected. If one or more cartridges of the production lot sample are defective, then the leak test shall be
performed on 100 percent of the lot being tested. All defective cartridges shall be rejected.
4.5.6 Cartridge radiographic examination. All cartridges shall be radiographically examined in accordance
with MIL-STD-453; any observable imperfections in assembly shall be cause for cartridge rejection. The
cartridges shall be 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 order beginning with
the number 001 in each production lot. The cartridge shall be arranged on trays or boards in consecutive
numerical orders, and each radiograph shall carry a permanent identification of the cartridges displayed thereon.
The radiograph identification shall include the item contract number, complete lot number, as stamped on the
cartridges, and the span of serial numbers displayed. Discontinuities in serial numbers shall be identified on the
X-ray. Defective cartridges found by the vendor shall be clearly identified on the X-ray and removed from the
production lot. The serial numbers shall be pen or ink stamped on the cartridges with approximately 1/8-inch-high
characters. The serial numbers shall be located apart from the other cartridge markings. Radiographs or copies
of the entire production lot shall accompany the ballistic sample to the activity conducting the production lot
acceptance test (see 6.2.).
4.5.7 Ballistic tests. The ballistic test sample shall be divided into three groups of as near equal number as
possible, to be conditioned at 65 ± 5 F, +70 ± 5 F and +200 ± 5 F respectively with the 2 extra cartridges
conditioned at 65 F and +200 F. The cartridges allocated for 65 ± 5 F and +200 ± 5 F shall be conditioned
for not less than 4 hours nor more than 24 hours. The cartridges allocated for +70 ± 5 F shall be conditioned for
not less than 4 hours. Cartridges shall be removed from conditioning and fired in the test fixture configuration
shown on Drawing 726AS874 within 3 minutes after removal. If any cartridge is not fired within 3 minutes after
removal from conditioning, it shall be reconditioned for not less than 4 hours nor more than 8 hours before test
firing. The reconditioning may be performed as many times as necessary.
4.5.7.1 Criteria of acceptability. Cartridges of the ballistic sample shall meet all the requirements of Drawing
847AS115. All cartridges subjected to the ballistic test of 4.5.7 shall meet the requirements of 3.6. A failure of
any cartridge to meet any one of these requirements shall be cause for rejection of the lot represented.
4.5.7.1.1 Misfire. The failure of any cartridge to fire shall be cause for rejection of the lot represented, unless
such failure is plainly attributable to faulty test equipment or procedure.
4.5.7.2 Retest. There shall be no retests except for misfires allowed by 4.5.7.1.1.
4.5.7.2.1 Test failure. If test failure is attributable to an assignable cause, excluding the test cartridge, original
test results should be discarded and that part of the test reconducted.
4.6 Examination of packaging. The preservation-packaging, packing, and marking of the cartridges, shall be
examined for conformance to the requirements of section 5.
