4.4.5 Methods of inspection.
4.4.5.1 Materials, components and processes. Compliance with
all requirements of Section 3 of this specification shall be
ascertained by current and continuing examination of inspection
and test data to determine that all components (parts,
subassemblies, and materials) have been inspected and tested and
found to comply with their respective drawing, specification or

processes have been followed.
4.4.5.2 Visual and mechanical inspections. The visual,
manual and mechanical inspections and tests shall verify
compliance with the requirements of Sections 3, 4, and 5 of the
specification in accordance with 4.4.2 herein.
4.4.5.3 Moisture.
4.4.5.3.1 First fire composition. The moisture content of
the first fire composition shall be determined in accordance with
MIL-STD-1234, Method 101.3. The special solvent to be used shall
be equal parts by volume of dimethylformamidemethyl alcohol and
anhydrous methanol.
4.4.5.3.2 Illuminant composition. The moisture content of
illuminant composition shall be determined in accordance with the
Karl Fischer Method as stated in MIL-STD-1234, Method 101.2 up to
paragraph 5.3. A 50 ml. sample of 1:1 dimethylformamidemethyl
alcohol solution shall be added into a 250 ml. Erlenmeyer flask
(fitted with a rubber stopper) containing 10 grams of the
pyrotechnic sample. (Exercise care to exclude atmospheric
moisture). The flask shall be stoppered and shaken vigorously to
thoroughly mix the solution and pyrotechnic sample. Allow the
solution to set 5 to 15 minutes. A blank sample of 1:1
dimethylformamide methanol solution shall be prepared as described
above.
A 60 ml. portion of methanol shall be transferred through
the sample porthole into the dry titration beaker containing a
plastic coated magnet. Stopper at once. The magnetic stirrer
shall be started and the water back-titrated in this solvent by
adding a slight excess of Karl Fischer reagent to produce a
reddish-brown color which persists for at least half a minute.
