6.2
Acquisition requirements.
Acquisition documents should specify the following:
a. Title, number, and date of the specification.
b. 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).
c. Kit size (or sizes) required (see 3.4 and 6.3).
d. Specify identification markings and caution notice (see 3.6.11).
e. Packaging requirements (see 5.1).
6.3 Basis of purchase. The coating covered by this specification should be
purchased by volume, the unit being a kit comprised of a primer and a topcoat,
each consisting of one quart of 57.75 cubic inches (component B) and one gallon of
2331 cubic inches (component A).
6.4 Qualification. With respect to products requiring qualification, awards will
be made only for such products which are, at the time set for opening of bids,
qualified for inclusion in the applicable Qualified Products List whether or not
such products have actually been so listed by that date. The attention of
contractor is called to this requirement and manufacturers are urged to arrange to
have the products that they propose to offer to the Government be tested for
qualification in order to be eligible for contracts or product orders covered by
this specification. The activity responsible for Qualified Products List is the
U.S. Army Research Laboratory, Weapons and Materials Research Directorate, ATTN:
AMSRL-WM-M, Aberdeen Proving Ground, MD 21005-5069.
6.5 Coating application. To insure adequate cure, the temperature of the
substrate being coated should be above 10°C (50°F). The pot life of a mixed sample
will be reduced by higher temperatures and increased by lower temperatures. To
avoid solvent entrapment and a subsequent loss of resistance properties, there
should be a minimum of 18 hours drying time between the primer and the topcoat. A
total film thickness should be 0.006 to 0.008 inches.
