30、ified by the tests and examination herein are classified as critical, major, or minor in accordance with DOD-STD-2 1 O 1. Tests and examinations that veri+, criticai charac6stics are identified by the symbol (C) and major characteristics by the symbol (M). The number following the classification sym
31、bol indicates the serial number of test or examhation. Tests and examinations which are not annotated with a classification code are classified minor. 4.3 First article inspection. First article inspection shall be performed after award of contract and prior to production by a facility designated in
32、 the contract (see 6.2). A first article sample acceptable for environmental and function testing shall be considered as a sample which has met the requirements of 3.2 through 3.4.2.3 and 3.7.

42、ected. 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. 45.6 Cartridge radiographic examination. All cartridges shall be radiographically examined in accorda
43、nce 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

Defective cartridges found by the vendor shall be clearly identified on the X-ray and removed from the production
46、 lot. The serial numbers shall be pen or ink stamped on the cartridges with approximately l8-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 activiv condu
47、cting the production lot acceptance test (see 6.2.). 4.5.7 Ballistic tests.

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 fing. The reconditioning may be performed as many times as necessary. 4.5.7.1 Critena of acceptability. Cartridges of the ballistic sample shall meet all the requirements of Drawing 847AS115. AU c
