(with fuze protector) shall be selected and subjected to the test as
specified in MIL-STD-331 with the following conditions:
a.  The fuze assembly will be assembled to an inert booster,
inert booster lead, and M230 Warhead (the Government shall supply
the warhead for the contractor's use) and with impact orientation of
the warhead-fuze assemblies for the drop test as follows:
(1)  Major axis horizontal
(2) Major axis 450 from vertical base down
(3)  Base down

specified. After satisfying the above requirement, one lot (a
mminimum lot size of one week's production) per month shall be
selected by the Government and subjected to and pass the Five Foot

criteria, the contractor shall be required to return to the three
(3) consecutive lot procedures above for process qualification.
