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 that may be helpful, but is not mandatory.)
6.1 Intended use. The notes specified in MIL-PRF-19500 are applicable to this specification.
6.2 Acquisition requirements. Acquisition documents must specify the following:
a.
Title, number, and date of this 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).
c.
Packaging requirements (see 5.1).
d.
Lead finish (see 3.4.1).
e.
Type designation and product assurance level.
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 Manufacturers' List (QML) whether or not such
products have actually been so listed by that date. The attention of the contractors is called to these requirements,
and manufacturers are urged to arrange to have the products that they propose to offer to the Federal Government
tested for qualification in order that they may be eligible to be awarded contracts or orders for the products covered
by this specification. Information pertaining to qualification of products may be obtained from Defense Supply Center,
Columbus, ATTN: DSCC/VQE, P.O. Box 3990, Columbus, OH 43216-5000.
6.4 Cross reference substitution information. The JANS version of 1N6638, 1N6642, or 1N6643
(MIL-S-19500/578) is preferred in lieu of the JANS1N4148-1. The JANS 1N6638 or 1N6642 is substitutable for the
JANS 1N4148-1 and shall be used in lieu of the JANS1N4148-1. A PIN for PIN replacement table follows, and these
devices are directly interchangeable.
