(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
Two (2) fuzes each must be dropped in the above (1, 2, 3)
orientations. No fuze shall be subjected to more than one drop.
The orientation of the Safety and Arming Device (specifically the
g-weight) of the fuze shall be random.
b. The Five Foot Drop Test, as specified in MIL-STD-331, shall
be performed until three (3) consecutive lots (a minimum lot size of
one week's production) have complied with the acceptance criteria
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
Drop Test. Should the one lot (per month) fail the acceptance
criteria, the contractor shall be required to return to the three
(3) consecutive lot procedures above for process qualification.
c. The fuzes shall be subjected to the tests and acceptance or
rejection criteria as specified in Table IV. Fuzes must be safe to
handle and safe to fire or dispose of (not necessarily operable)
