MIL-DTL-20517J (AR)
increased to two hundred (200) simulator assemblies and tested in accordance with
4.4.6.1.
4.4.6.4 Normal to reduced sampling plan. When normal sampling is in effect (see
4.4.6.3), reduced sampling may be resumed when the root cause of the nonconformance
requiring normal sampling has been corrected and three (3) numerically consecutive lots
have been accepted. Resubmitted lots shall not be used to meet the criteria of
"numerically consecutive lots".
4.4.7 Primer deterioration. A sample of 315 primers shall be selected at random
from each lot. If four (4) or more primers fail to function, the lot shall be rejected. If
more than one defect is found, a second sample of 315 shall be selected at random and
tested. If in the combined first and second sample a total of five (5) or more defects are
found the lot shall be rejected. The test shall be performed as specified in the applicable
primer specification.
4.4.8 Air leakage. This test shall be performed 100 percent in accordance with the
procedure specified in 4.5.6. All assemblies that fail to comply with the requirement shall
be classed as a major defect and removed from the lot. (Non-destructive test)
4.4.9 Radiographic examination. This test shall be performed 100 percent and at
level VII verification in accordance with the procedures specified in 4.5.7. (Non-
destructive test) Radiographic equipment procedures and evaluation shall be in
accordance with ASTM E 1742. Radiographic personnel shall be qualified in accordance
with NAS 410. Automated radiographic equipment and procedures shall be used to the
maximum extent possible.
4.5 Methods of inspection.
4.5.1 Moisture content. The test given in this paragraph and in 4.5.2 shall be
performed with prescribed procedures for replicate determinations given in standard
analytical chemistry textbooks.
4.5.1.1 Black powder. Determine the moisture content of the black powder using
Method 102.2 given in MIL-STD-1234 except that a heating temperature of 70 ± 2°C
shall be used.
4.5.1.2 Flash powder. Determine the moisture content of the flash powder using
Method 102.1 given in MIL-STD-1234 except that a heating temperature of 70 ± 2°C
shall be used.
4.5.1.3 Felt and chipboard. Accurately weigh (to the nearest 0.001 gram)
approximately a 10 gram portion of the sample and quantitatively transfer to a tared
weighing dish. Determine the moisture content of the felt and chipboard in accordance
with Method 102.1 given in MIL-STD-1234.
