MIL-DTL-46610F
TABLE VIII. First article and conformance inspection - Continued
Note 1. Failure of the primers to comply with the requirements shall be cause for rejection of the
lot subject to the testing of a second sample consisting of double the quantity used in the first
test. Failure of the primers of the second sample to comply with the requirements shall be cause
for rejection of the lot. For first article, no retest is permitted. (See figure 1 for calculation sheet
for sensitivity and skewness.)
Note 2. Failure of two or more cartridges to comply with the applicable requirements shall be
cause for rejection of the lot; if one cartridge fails in the first test, a second sample, consisting of
double the quantity used in the first test, may be tested, providing that the action time of the
failing cartridge does not exceed 0.020 seconds. If any failing cartridges are found in the second
test, the primer lot shall be rejected. For first article, if one or more cartridges fail, the first
article sample shall be rejected. No retest is permitted.
Note 3. All cartridges for these tests shall be loaded with propellant from an acceptance lot with
known level of performance.
Note 4. Reduced testing. Testing for these requirements may be reduced if five consecutive lots,
all using the same primer mix and production process, have met the applicable requirements.
The reduced plan shall consist of testing one out of every five lots submitted. The lots tested
under the reduced plan shall be selected randomly. Testing shall be resumed on each lot when
the primer formulation or production process changes. Testing shall be resumed on each lot for a
particular requirement when the requirement specified is not met.
Note 5. The lot shall be rejected when function and casualty defects plus defects observed in all
other firing tests exceed the acceptance number for the cumulative sample in Table IX. If the
number of defects found in the first test exceeds the acceptance number for the first sample, but
is equal to or less than the acceptance number for the cumulative sample, a second sample
consisting of double the quantities specified under function and casualty test, shall be fired in all
the service weapons specified there for. This procedure shall apply regardless of the weapon or
weapons in which the firing defects occurred in the first test. If the total number of defects in the
combined first and second samples exceeds the acceptance number for the cumulative sample,
the lot shall be rejected. If, in testing a second sample, defects other than those for which the
second sample is being tested should occur to the extent that they exceed the acceptance number
for the cumulative sample, the primer lot shall be rejected. For first article, acceptance shall be
based on the acceptance number for the first sample. No retest is permitted.
Note 6. This test shall be performed on the first article sample only. Failure to comply with
applicable requirements will result in failure of first article.
Note 7. Failure of the priming composition to comply with the applicable requirements shall be
cause for rejection of the initial production sample. For primer lot acceptance, if the primer
composition fails to comply with the applicable requirements, a second sample shall be selected
and analyzed. If the second sample complies, the lot shall be accepted. Testing for the priming
composition may be reduced if five consecutive lots, all using the same primer mix and
production process, have met the requirements of 3.9. The reduced plan shall consist of testing
one out of every ten lots produced. The lots tested under the reduced plan shall be selected
randomly. Testing of every lot shall be resumed when the requirements of 3.9 are not complied
with or when the primer mix or production process is changed.
Note 8. Number of primers necessary to yield 3 grams of priming composition.
Note 9. This test shall be performed on No. 34 primers for use in M82 primers.
