MIL-PRF-29163C
4.7.1 Buoyancy test. The swivel shall be loaded with 19 or 45 kg, as required by the size of
buoy(s) (see 3.7.1 and 3.7.2), and then placed in a tank of water. Submergence of the buoy(s)
more than one-half of its length from top to bottom shall be cause for rejection. Failure of the
swivel, eye, or rod to stay attached to the buoy(s) shall also be cause for rejection.
4.7.2 Total submergence. The swivel shall be sufficiently loaded to cause total submergence of
the buoy(s) in the test tank. The buoy(s) shall be left in this condition for not less than one hour.
Failure of the swivel, eye, or tension rod to stay attached to the buoy, or cracking of the exterior
surface anywhere on the buoy(s), shall be cause for rejection.
4.7.3 Drop test. The buoy(s) of each size shall be hoisted to a height of 3 048 millimetre (mm)
allowing buoy(s) to fall freely to a hard surface. Damage to the exterior surface or fittings
rendering the buoy(s) unusable or reducing their function shall be cause for rejection. This test
shall be performed at 0 degrees Celsius (°C) ± 3 °C.
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 is helpful, but is not
mandatory.)
6.1 Intended use. The marker buoys are intended for use as markers for anchors around pontoon
causeways and buoyant fuel lines. When used around pontoon causeways, the marker buoys are
used with mooring. When used around buoyant fuel lines, the marker buoys are used without
mooring.
6.2 Acquisition requirements. Acquisition documents must specify the following:
a. Title, number, and date of this specification.
b. Size and shape required (see 1.2).
c. When two size 1 buoys in combination are requested instead of a size 2 buoy (see 1.2
and 3.7.2).
d. Issue of DoDISS to be cited in the solicitation, and if required, the specific issue of
individual documents referenced (see 2.2.1 and 2.3).
e. When epoxy antifoulant is added to the exterior surface (see 3.1.2).
