The lot shall not be penalized if condition a. is observed. However, this
condition shall be reported for information. The "Acc" number shall be
zero (0) and the "Rej" number 3, for misfired associated with conditions
b, c, or d. The second sample for evaluation of misfires associated with
conditions b, c, or d shall consist of the function and casualty second
sample (see Table I, Note 13/). The lot shall be rejected if either con-
dition e or f is observed. Misfire(s) occurring in the waterproofness
test shall be handled in accordance with AMCR 715-505, Volume 8.
See Dwg. C7258801, a detail of IEL 7567234, for classifying splits and
ruptures in fired cartridge cases. If a longitudinal split or circumfer-
ential rupture (partial) extends into two or more defined areas, only the
most severe defect criterion of Table 11 for the areas involved shall apply.
If a rupture results in separation of the cartridge case into two or more
portions, the defect shall be classed as a complete circumferential rupture.
Metal sheared or missing from the fired cartridge case exterior, such
as, rim or neck shears, shall be classed as a defect. The lot shall not be
penalized for shavings of metal from the interior wall of the case neck in
the crimped area.
For classification as a defect, there must be evidence either by recovery
of the band or portion thereof, or by hole(s) in the fragmentation screens.
The lot shall not be penalized for normal band fringing or the separation
of band fragments having no evidence of band seat serration imprint and
length not exceeding 0.5 inch.
Breakup or separation of projectile metal part(s), except rotating band,
as witnessed by recovery of the part(s) or fragment(s), or by hole(s) in
the fragmentation screens, shall be classed as a defect.
