MIL-DTL-82604A (OS)
4.5.11.3 Testing procedure. Use 2N + 2 (where N equals the number of explosives used)
tubes similar to the heating tube portion of the apparatus in procedure 4.1 of method 403.1.3 in
MIL-STD-286. For controls, add 2.5 g of the dried compound to each of two tubes and 2.5 g of
each explosive to additional individual tubes. Place uniform mixtures of 2.5/2.5 g of the
asphaltic compound and each of the explosives specified in the test in single separate tubes.
Obtain uniform distribution or mixing by carefully layering alternate portions of the dried
compound with the explosive. After the addition of each portion, lightly tamp the mixture with a
glass or metal rod to insure intimate contact of the materials. After all the samples have been
prepared, connect the respective heating tubes with the capillary tubes as prescribed and
conduct the vacuum stability test according to method 403.1.3 of MIL-STD-286 at 100 ± 0.5 șC
for 48 hours. Make all readings at room temperature with the samples removed from the bath.
Correct the readings of both the controls and the test samples to standard conditions of
temperature and pressure, and check for compliance with 3.4.
4.5.11.4 Calculation of reactivity. Calculate the reactivity of each of the explosive
materials with the coating compound as follows:
Reactivity in ml of gas = X - (Y + Z)
Where:
X = ml of gas produced by the mixture of explosive material and asphaltic
compound
Y = ml of gas produced by the explosive material alone
Z = ml of gas produced by the asphaltic compound alone.
4.5.12 Fast cookoff test. The three sample bombs (4.2.2) meeting the application-coating
requirements of 3.5 shall survive the fast cookoff test in accordance with STANAG 4240.
5. PACKAGING.
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified
in the contract or order (see 6.2). When actual packaging of materiel is to be performed by
DOD personnel or in-house contractor personnel, these personnel need to contact the
responsible packaging activity to ascertain packaging requirements. Packaging requirements
are maintained by the Inventory Control Point's packaging activities within the Military Service or
Defense Agency, or within the military service's system commands. Packaging data retrieval is
available from the managing Military Department's or Defense Agency's automated packaging
files, CD-ROM products, or by contacting the responsible packaging activity.
6. NOTES.
(This section contains information of a general or explanatory nature which may be helpful, but
is not mandatory.)
6.1 Intended use. The high melting, hotmelt asphaltic compound covered by this
specification is intended for use as a protective lining for fabricated metal cases in applications
where charges of high explosives are poured into the case and require thermal insulation from
the elevated temperature environment of a fuel fire. As this compound was developed for use in
military ordnance, there is no commercial application.
