4.4.4.2 Unlisted Firing Defects. -The lot shall be suspended and referred
to the contracting officer for disposition, if a malfunction or casualty
not covered by this specification occurring in any firing test, indicates
that the product is unsuited for the purpose intended.
4.4.5 Packaging, Packing and Marking Inspection. - Inspection for packaging,
packing and marking shall be in accordance with MIL-STD-644, as applicable
to the drawing.
4.4.6 Inspection Equipment. -Index of Inspection Equipment List No. IEL
7567234 identifies the applicable Inspection Equipment List required to
perform examination and tests prescribed herein. Equipment design shall
be in accordance with code designation on the applicable IEL (reference
is made to Inspection Equipment List for definition of coding, see Dwg.
B11075228, a detail of IEL 7567234).
4.5 Test Methods and Procedures.
4.5.1 Projectile Extraction.-The method of test shall be as prescsibed
by AMCR 715-505, Volume 8.
4.5.2
Electrical Resistance.
4.5.2.1 Primed Cartridge Cases. -The equipment and circuitry specified by
IEL 7567234 shall be used to measure the resistance of the primer In each
primed cartridge case.
4.5 .2.2 Electrical Resistance Verification. - A Simpson Volt-Ohm-Ammeter,
Model 260, or approved equal, shall be used to measure the resistance of
the primer in each primed cartridge case from the projectile extraction
test sample. Only the RX 100 and RX 100 and RX 10,000 scales of the meter will be
used in order limit the applied voltage and current, respectively, to
7.5 volts and 1.4 milliamperes, maximum.
4.5.3 Propellant Contamination.-The propellant from each of the cartridges
tested for projectile extraction shall be examined visually for contamination,
as prescribed by AMCR 715-505, Volume 8.
4.5.4 Projectile Torque.-Equipment shall be as specified by IEL 7567234.
Each cartridge of the test sample shall be marked with a light scratch
extending axially across the rotating band onto the case neck. Torque as
specified by 3.6 shall be applied slowly to the projectile. Movement of
the projectile with respect to the cartridge case, detectable by misalign-
ment in the scratch mark, shall be recorded.
