4.3.3.5 Air pressure - Critical defect - Code No. 03032. -
Each shell assembly that has passed the hydrostatic pressure
test, as indicated by the letter "H" stamped on the body, shall,
after completion of the drying cycle be subjected to a submerged
air pressure test. Any shell assembly failing to comply with
requirements specified on Dwg. 9238883 as evidenced by air bubbles
rising to surface of water shall be rejected. Air bubbles caused
by entrapped air on the outside of the shell shall not be cause for
rejection of the shell assembly. Shell assemblies which comply with
the requirements of Dwg. 9238883 shall be stamped with the letter
"A" as indicated on the assembly drawing. The test shall be performed
as specified in 4.4.6 using equipment in accordance with 4.3.4.
4.3.3.6 Salt Spray Test - Major defect (see 3.5) Code No.
04012. - The sample size for this test shall be as follows:
During production, one warhead from each days production, shall
be subjected to the salt spray test as specified in 4.4.8, until
five consecutive days production have successfully passed the test.
Sampling shall then be reduced to one sample twice per week,
upon reduced sampling if one failure occurs, corrective action shall
be taken and sampling shall revert to one specimen from each days
production until five consecutive days' production have again
successfully passed the test. If two consecutive failures occur
after the contractor has been notified to take corrective action
in either the original sampling plan or the reduced sampling plan,
inspection for acceptance shall be stopped until necessary corrective
action has been taken. Any specimen (warhead) which does not comply
with any of the following test criteria shall be considered a failure.
The specimen, when subjected to the salt spray test as specified in
4.4.8, shall show no more than 1/8 inch creepage, blistering, or
loss of adhesion of the paint as measured from the scribe mark. At
all other points there shall be no more than a trace of film failure
such as blistering, or corrosion, and not more than twenty scattered
blisters, none larger than 3/16 inch in diameter on the painted sur-
face of the warhead. This is intended that the maximum amount of
corrosion in the salt spray test be comparable to photograph 8-1
in ASTM Standard Method of Evaluation Degree of Resistance to Rust-
ing obtained with paint or iron and steel surfaces, D610-43. This
test shall be performed as specified in 4.4.8 using equipment in
accordance with 4.3.4.
4.3.3,7 Drop Test - Major Defect - Code No. 04013 -
Beginning with the first lot and continuing until five consecutive
lots have been tested a sample from each lot shall be subjected to
a drop test as specified in 4.4.7 using equipment in accordance
with 4.3.4, Upon satisfactory results from five consecutive lots
the contractor may reduce testing to a sample from one randomly
selected lot per month. The contractor shall return to the five
lot requirement upon failure of any lot. The sample shall consist
of 23 randomly selected painted assemblies which have passed all
other requirements of this specification. The lot represented by
the sample shall be rejected if two (2) or more warheads fail to
