MIL-DTL-20517J (AR)
4.4 Examination.
4.4.1 Chemical Sampling. Representative samples shall be tested in accordance
with ASTM E 300 procedure for solids.
4.4.2 Moisture determination. Moisture determinations shall be performed on the
components specified in Table III. Adequate controls shall be provided to assure that the
requirements are met. For verification, one sample of each material from each eight (8)
hours of production shall be selected, and subjected to test. A composite sample shall not
be used. If the moisture content of the sample exceeds the requirement, that quantity or
sub-lot of material represented by the sample shall not be used in production. If the
quantity of material or sub-lot with excessive moisture has been used in loading and
packing, the remaining unloaded and unpacked material shall not be used in production,
and the loaded and packed simulators shall be rejected. Test shall be performed as
specified in 4.5.1.

4.4.3 Determination of flash powder composition. A sample of flash powder,
drawing 8848485, of not less than 5 grams shall be selected from each batch for test in
accordance with 4.5.2, using the procedure given in ASTM E300 for solids. If the sample
fails to comply with the requirement specified, the batch shall be rejected. Failure of a
batch shall be considered a major defect.
4.4.4 Compressive tube strength. Twenty six (26) tubes total from each lot shall
be tested in axial and diametrical directions to ensure the tube shall not interfere with the
rupture of the charge case assembly in functioning. Failure to comply with requirements
on drawing 8848484 shall be considered a major defect.
4.4.4.1 Axial. Thirteen (13) tubes shall be selected randomly from each lot for
test. If one or more tubes fail to comply with the requirement, the lot shall be rejected.
The test shall be performed as specified in 4.5.3.1. (Destructive test)
4.4.4.2 Diametrical. Thirteen (13) Tubes shall be selected randomly from each lot
for test. If one or more tubes fail to comply with the requirement, the lot shall be rejected.
The test shall be performed as specified in 4.5.3.2. (Destructive test)
4.4.5 Fragmentation. Twenty (20) loaded charge case assemblies shall be selected
from each lot and subjected to static functioning in accordance with the method specified
