MIL-DTL-12883F
6. NOTES
(This section contains information of a general or explanatory nature that may be helpful, but is not
mandatory.)
6.1 The sockets covered by this specification are military unique because they must be able to operate
satisfactory under high altitude 50,000 feet (15.2 km), vibration 36.6 rms G min, 50 g's of shock, and
temperatures ranging from - 65 to +125 degrees Celsius. Commercial electronic components are not
designed to withstand such extreme and sudden environmental conditions and would experience
catastrophic failure.
6.2 Intended use. All sockets and accessories covered by this specification are intended for application
in electronic and electrical circuits under conditions that are not in excess of the ratings established herein
(see 3.1), for the particular socket or accessory. Where application of sockets or accessories covered by
this specification is contemplated for conditions in excess of those stated above, it is advisable that
approval of the cognizant bureau or service be obtained.
6.2.1 Tube shields. Tube shields, when required in conjunction with sockets, should be in accordance
with MIL-S-24251.
6.2.2 Tin whisker growth. The use of pure tin may exhibit tin whisker growth problems (days to months
to years) after manufacture. Tin whiskers can develop under typical operating conditions on any product
type that uses lead-free pure tin coatings. Conformal coatings applied over top of a whisker-prone surface
will not prevent the formation of tin whiskers. Alloys of 3 percent lead have shown to inhibit the growth of
tin whiskers.
6.3 Acquisition requirements. Acquisition documents must specify the following:
a. Title, number, and date of the specification.
b. Title, number, and date of the applicable specification sheet, and the complete PIN (see 1.2.1 and
3.1).
c.
Certificate of compliance covering materials, when required.
d. Issue of DODISS to be cited in the solicitation, and if required, the specific issue of individual
documents referenced (see 2.1 and 2.2).
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 Products List QPL No. 12883
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 purchase orders for the products covered by this specification. Information pertaining
to qualification of products may be obtained from the Defense Supply Center Columbus, ATTN: DSCC-
VQP, P.O. Box 3990, Columbus, Ohio 43216-5000. Application procedures should conform to the
"Provisions Governing Qualification" (see 6.3.1).
6.4.1 Provisions governing qualification. Copies of "Provisions Governing Qualification" may be obtained
upon application to Standardization Document Order Desk, Building 4D, 700 Robbins Avenue,
Philadelphia, PA 19111-5094.
