MIL-DTL-3301D
3.11 Flash point. The flash point of the asphaltic compound shall be not less than 260 ºC (500 ºF) when
tested as specified in 4.4.14.
3.12 Reactivity. When subjected to the vacuum stability test-as specified in 4.4.15, the reactivity of the
asphaltic compound with TNT , HBX-1, HBX-3, H-6, and tritonal explosives shall not exceed 3.0
milliliters of gas over and above that generated by the controls when the test is conducted at 100 ± 0.5 ºC
for 40 hours. The reactivity of the asphaltic compound with Minol-2 explosive shall not exceed 3.5
milliliters of gas over and above that generated by the controls when the test is conducted at 90 ± 0.5 ºC
for 40 hours. The explosives tested with the asphaltic compound in the vacuum stability test shall be in
accordance with the following: TNT shall conform to MIL-DTL-248, Type I; HBX-1, HBX-3, and H-6
shall conform to MIL-E-22267; Minol-2 shall conform to MIL-M-14745; Tritonal shall consist of 80 ± 3
percent by weight TNT, MIL-T-248, Type I and 20 ± 3 percent by weight aluminum powder, MIL-DTL-
512, Type 3, Class 7.
3.13 Workmanship. The asphaltic compound ingredients shall be processed in a manner that will
produce the high quality material necessary to meet the requirements of this specification. The finished
product shall be homogeneous, free from a foam like texture on its surface, or other defects that could
adversely affect its intended use.
4. VERIFICATION
4.1 Classification of inspections. The inspection requirements specified herein are classified as follows:
a. First article inspection (see 4.2)
b. Quality conformance inspection (see 4.3)
4.2 First article inspection. The first article inspection shall consist of a review for approval of the
submitted manufacturer's reports and subjecting the first article sample (4.2.1) to examination and testing
to determine conformance to the requirements of this specification.
4.2.1 First article samples. Unless otherwise specified in the contract or purchase order (see 6.2), the
following applies to the first article. A test report from the manufacturer or a commercial laboratory
showing the formula number of the compound, formulation and composition of the asphaltic compound
including the identification of ingredient samples by specific chemical name in addition to trade name,
and laboratory data showing complete test results required by this specification except reactivity shall be
forwarded to the procuring activity before first article samples are supplied (see 6.3). The first article
samples shall consist of 10 pounds of compound and 1 pound of each ingredient used. The samples shall
be forwarded to the agency responsible for first article testing as designated in the solicitation or contract
(see 6.3). The samples shall be plainly identified by securely attached durable tags or labels marked with
the following information:
(a) Sample for first article inspection
(b) COMPOUND, ASPHALTIC, HOT-MELT ('CAVITY LINING)
(c) Name and address of manufacturer
(d) Location and identity of the plant which produced the samples
(e) Manufacturer's identification
