Metal parts security
If two or more units of the sample have an average radial void, between
the seated band and the band seat, greater than 0.004 inch, the lot shall
be rejected.  If one unit of the sample has an average radial void greater
than 0.004 inch, a second sample consisting of the same number of units as
specified for the first sample shall be tested.  If in the accumulated
samples, two or more units have an average radial void greater than 0.004
inch, the lot shall be rejected.
Failure of the flaw detector to reject PCS No. 1 shall be cause for re-
jection of all assemblies inspected for "soundness" since the preceding test
and shall require requalification of the equipment for automatic inspection.
(see 4.5.3)
Rejection of one or more units of the sample by the flaw detector in the
test for body metal soundness shall be cause for rejection of the lot.
Failure of the phosphate coating on the standard panels to comply with
the applicable requirements shall be cause for rejection of all projectiles
phosphate since the preceding test.
If two or more units of the sample fail to comply with the requirement
for paint adhesion, the lot shall be rejected.  If one unit of the sample
fails to comply with the requirement, a second sample consisting of the
same number of units as specified for the first sample shall be tested.
If in the accumulated samples, two or more units fail to comply with the
requirement for paint adhesion, the lot shall be rejected.
