6. NOTES
(This section contains information of a general or explanatory nature that may be helpful,
but is not mandatory.)
6.1 Intended use. The barrier materials covered by this specification are intended for use in
specialized military methods of preservation. The combination of all performance characteristics of
MIL-PRF-22019; vapor inhibitor ability; vapor inhibitor ability after exhaustion; transparency;
storage stability; long term protection; contact corrosivity; seam and fabrication strength;
compatibility with copper, blocking and puncture resistance; delamination; water resistance of
markings, provides the necessary requirements for protection from exposure to the extremes of the
navy/naval aviation environment. Navy/naval aviation items are exposed to high moisture, high salt
concentration, transfer at sea, rough handling, and minimal storage conditions. There are no
commercial equivalents that meet the physical, mechanical, and corrosion requirements necessary to
protect materiel that is exposed to the operational naval aviation environment. Specifically,
specialized Method of Preservation GS of MIL-STD-2073-1 uses MIL-PRF-22019 as the premier
source of barrier materials that provides volatile corrosion inhibitor protection for applicable items
encountering the above conditions.
6.1.1 Type I use. Type I material is intended for use where a heat-sealable, barrier material
with corrosion inhibiting ability is required.
6.1.2 Type II use. Type II material is intended for use where either production or custom
hand processing requires a cold-sealable barrier material with corrosion inhibiting ability.
6.2 Acquisition requirements. Acquisition documents should specify the following:
a.
Title, number, and date of the specification.
b.
Type of barrier material (see 1.2).
c.
Form (rolls or flat cut) and size required (see 3.4).
d.
Packaging requirements (see 5.1).
6.3 Heat-seal equipment. In the interest of standardization and for ease of manipulation,
the seals for test under this specification should be effected on a jaw-type heat-sealer. This,
however, should not be construed as an indication of Governmental preference in regard to
sealing equipment. It is not intended that the operating temperature of heat-sealing equipment be
limited to 450 °F or less. While equipment may be operated at temperatures exceeding 450 °F to
accomplish a seal, the barrier material should also be capable of being heat-sealed at
temperatures of 450 °F or less.
6.4 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
