MIL-DTL-6000D
4.8.12 Water and alcohol resistance (see 3.5.12). The hose shall be tested for resistance to
exposure with water and alcohol and shall meet the requirements in 3.5.12. The following details shall
apply:
a. Test specimens from the tube shall be immersed in a solution of 50 percent water and 50
percent alcohol, in accordance with SAE-AMS3002, at a temperature of 158 °F (70 °C) for 24
hours under reflux.
b. The samples shall be tested in accordance with ASTM D412 except that the tensile strength
shall be determined within 15 minutes after they are removed from the solution.
c. Tensile strength calculations shall be based on the original cross-sectional area of the test
specimens.
5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the
contract or order (see 6.2). When packaging of materiel is to be performed by DoD 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 intended use of the hose is for use in fuel, oil, coolant, water, and alcohol
lines in aircraft engine installations. If used in lengths greater than 18 inches, however, the hose has a
tendency to collapse. The rubber hose covered by this specification is a military unique item that is
designed to withstand flexing at low temperature -40°F (-40°C), and be capable of high temperature
circulation to various types of fluids.
6.1.1 Interoperability and compatibility. The interoperability and compatibility to new and existing
systems has been assured through strict adherence to the military detail specification requirements.
Manufacturers of these items and users place great reliance on the detailed technical requirements to
ensure the products meet the interoperability and compatibility requirements while encountering rapid
ambient temperature fluctuations.
6.2 Acquisition requirements. Acquisition documents must specify the following:
a.
Title, number, and date of this specification.
b.
Size and quantity of hose required.
c.
Length of hose when lengths greater than 10 feet are required.
d.
Shelf life (see 6.2.1)
Packaging requirements (see 5.1).
