5. PACKAGING
5.1 Packaging. For acquisition purposes, the packaging requirements shall be as specified in the
contract or order (see 6.2). When packaging of materiel is to be performed by DoD or in-house contractor
personnel, these personnel need to contact the responsible packaging activity to ascertain packaging
requirements. Packaging requirements are maintained by the Inventory Control Point's packaging
activities within the Military Service or Defense Agency, or within the military service's system commands.
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.

products which are, at the time of award of contract, qualified for inclusion in Qualified Products List QPL
No. 3950 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 via email to vqp.chief@dla.mil or from the
DLA Land and Maritime, Attn: VQP, 3990 East Broad Street, Columbus, OH 43213-1199. An online
listing of products qualified to this specification may be found in the Qualified Products Database (QPD)
6.3 Tin whisker growth. The use of alloys with tin content greater than 97 percent, by mass, may
exhibit tin whisker growth problems after manufacture. Tin whiskers may occur anytime from a day to
years after manufacture and can develop under typical operating conditions, on products that use such
materials. Conformal coatings applied over top of a whisker-prone surface will not prevent the formation
of tin whiskers. Alloys of 3 percent lead, by mass, have shown to inhibit the growth of tin whiskers. For
additional information on this matter, refer to ASTM-B545 (Standard Specification for Electrodeposited
Coatings of Tin).
