4.7 Test methods and procedures.
4.7.1 Ignition device x-ray. Prior to assembly into the cartridge, the ignition device shall be
radiographically examined in accordance with ASTM E1742. Each ignition device shall be x-rayed on
boards or trays with the cup side perpendicular to the rays. The x-ray negatives shall be identified by item
nomenclature and by lot number. Ignition devices are to be left mounted to the boards or trays until after
the x-rays have been reviewed and defects identified to facilitate removal of defective units. After
screening, the x-ray negatives with defectives identified, shall be forwarded to the engineering activity
designated by the acquiring activity. Interpretation of the radiographic films shall verify the following:
missing or abnormally thin charge; charge broken, cracked or porous; cracked or off-center anvil or other
misplaced or deformed inert parts; anvil abnormally close to the ignition device cup dome; and all other
observable defects in assembly.
4.7.2 Hardness. Ten units from each heat-treated lot of components shall be tested with a hardness tester.
Failure of a unit to comply with the requirements of the drawings shall be cause for rejection of the lot of
components.
4.7.3 Protective finish. Unless otherwise specified (see 6.2), sampling plans and procedures in the
determination of acceptability of coated parts shall be in accordance with the provisions set forth in tables
IV and V and MIL-A-8625.
4.7.4 Radiographic examination. All assembled cartridges shall be radiographically examined in
accordance with ASTM E1742. 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 serial numbers
shall be in consecutive order beginning with the number 001 in each production lot. The cartridges shall
be arranged on trays or boards in consecutive numerical order, and each radiograph shall carry a
permanent identification of the cartridges displayed thereon. The radiograph plate identification shall
include item nomenclature, the complete lot number as stamped on the cartridges, the span of serial
numbers displayed, and the contract number. Cartridges having any observable imperfections in assembly
shall be cause for rejection. Radiographs of the entire production lot shall accompany the ballistic sample
to the activity conducting the production lot acceptance test. Discontinuities in serial numbers shall be
