apply a compression load to the container assembly until the
container ends make contact with the precision block. The
reading at the initial point of contact with the precision

Results shall be recorded and
evaluated to determine compliance with the requirements. The
application of the compression load shall be accomplished
within 15 seconds, maximum.  Data results from this test will
be submitted in accordance with DI-T-1906.

cartridge being placed in the corner positions of the container.
Sixteen rounds (two boxes) shall be conditioned to -50F, min.
and sixteen rounds (two boxes) shall be conditioned to +145F,
min. for a minimum of 24 hours.  The cartridges shall be
subjected to electrodynamics transportation-vibration in accor-
dance with Method 514.2, Procedure X of MIL-STD-810 for simu-
lated truck and simulated two-wheel trailer transportation. The
test shall be conducted at a goverment-approved facility.  Test
cartridges shall remain boxed (packaged) throughout the test.
Cartridges shall be tested on two axes, i.e., 1 box vertically

4.5.6  Water repellency test.  The container assemblies
shall be tested for the presence of silicone by brief immersion
in water (12 seconds) and inspection for "beading" or
non-wetting.  The container is held between the thumb and
finger in such a way as to cover the fill hole and permit
complete immersion of the container; the assembly shall then be
withdrawn and examined.  A container shall be rejected if it
shows a lack of silicone or incomplete coverage as evidenced by
wetting or lack of beading.  NOTE:  Container assemblies shall
be dried in air for at least 24 hours before further use.
