the oven at 66.1°C (151°F). Place the drip shield around the disc. After 15
minutes soaking at the test temperature, start the motor and run for 15
minutes. Remove the disc, cool and weigh with the grease remaining thereon.
Calculate the percent of grease remaining on the disc. Perform this procedure
in triplicate and report to the nearest 1 percent, the average percent
remaining on the disc.
4.4.7 Aquatic biodegradability. If one of the acceptable alternative
test methods (listed in note 2 of Table II) is used for biodegradability,
report the standard method used.
4.4.8 Aquatic toxicity. In accordance with ASTM Standard Practice D
6081, prepare 4 water accommodated fractions (WAFs) for testing by loading
1000 ppm, 100 ppm, 10 ppm, and 1 ppm by weight of grease to equal volumes of
seawater and stirring at a low speed (a vortex of 5% - 10% of sample height).
These WAFs should then be subjected to a static, non-renewal, 48-hour mysid
(Mysidopsis Bahia) acute toxicity test in seawater per EPA/600/4-90/027F.

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 material 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.

NOTES
(This section contains information of a general or explanatory nature,
which may be helpful but is not mandatory.)
6.1 Intended use. Type I or II wire rope and exposed gear grease is
intended to provide lubrication and corrosion protection for running ropes and
exposed gears. Type II provides an environmentally preferable formulation for
applications where the potential for loss of lubricant to the environment is
greater.
6.2 Acquisition requirements.
Acquisition documents should specify the
following:
(a)
Title, number, and date of this specification.
(b)
Type of grease (I or II).
(c)
Packaging requirements (see 5.1).
(d)
Issue of DoDISS to be cited in the solicitation, and if
required, the specific issue of individual documents referenced
(see 2.2.1).
(e)
Date of ordering and date of supply.
(f)
Quantity.
(g)
Whether a Material Safety Data Sheet is required.
(h)
Whether NEHC toxicity evaluation is required (see 6.5).
6.3 Qualification. With respect to products requiring qualification,
awards will be made only for products which are, at the time of award of
contract, qualified for inclusion in Qualified Products List, QPL-18458,
whether or not such products have actually been so listed by that date. The
attention of the contractors is called to these requirements, and
