MIL-DTL-3100H
machine shall be started and the tire stripped from the metal base. The tire shall be stripped from
not less than 75% of the circumference of the wheel. If, during the test, the tire begins to tear
instead of separating wholly from the wheel, the tire shall be cut to the metal base with a knife.
Force measurements shall be permanently observed throughout the test. Any force less than
100 pounds per inch of width shall be cause for rejection. The ambient temperature during the
test shall be not less than 70°F and not more than 110°F, and the actual temperature shall be
noted.
4.6.6 Ozone resistance test. To determine conformance to 3.5.3, the tires shall be tested
as follows.
4.6.6.1 Specimen. The size of the specimens shall be in accordance with procedure B of
ASTM D518 and smoothly finished in accordance with methods specified in ASTM D3182 and
ASTM D3183.
4.6.6.2 Procedure. The specimen shall be tested in accordance with procedure B of
ASTM D518, except the length of clamping strips shall facilitate placement within the ozone test
chamber. The specimens shall be placed in the chamber and exposed for 7 days to a temperature
of 104°F +3.6°F in an air-ozone mixture having a partial ozone pressure of 50 +5 millipascals
(mPa) per ASTM D1149.
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, these personnel need to contact the responsible packaging activity to ascertain
requisite packaging requirements. Packaging requirements are maintained by the Inventory
Control Point's packaging activity within the Military Department or Defense Agency, or within
the Military Department's System Command. 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 wheel assemblies described in this specification are intended for
vehicle or track support on track laying military vehicles. Since these wheel assemblies must
operate with loads commensurate with tactical battlefield conditions (see tables I and II), under
which commercial items would experience catastrophic failure, they are military unique.
