6.5 Maintainability demonstration. Experience has shown that conducting maintainability demonstration in
accordance with MIL-HDBK-470 satisfies the requirements of this specification (see 3.4.6, 4.8 and 6.2).
6.6 Threaded parts (see 3.3.1.10). Experience has shown that threaded parts in accordance with MIL-HDBK-454,
guideline 12 satisfy the requirements of this specification.
6.7 Tin whisker growth: The use of alloys with tin content greater than 97 percent, by mass, may exhibit tin
whisker growth problems after manufactures. Tin whiskers may occur anytime form 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).
6.8. Environmentally preferable material. Environmentally preferable or Biobased materials should be used to the
maximum extent possible to meet the requirements of this specification. As of the dating of this document, the U.S.
Environmental Protection Agency (EPA) is focusing efforts on reducing 31 priority chemicals. The list of chemicals
and additional information is available on their website at https://www.epa.gov/osw/hazard/wastemin/priority.htm.
Included in the list of 31 priority chemicals are cadmium, lead, and mercury. Use of these materials should be
minimized or eliminated unless needed to meet the requirements specified herein (see Section 3)..
6.9 Changes from previous issue. The margins of this specification are marked with vertical lines to
indicate where changes from the previous issue were made. This was done as a convenience only and the
Government assumes no liability whatsoever for any inaccuracies in these notations. Bidders and contractors are
cautioned to evaluate the requirements of this document based on the entire content irrespective of the marginal
notations and relationship to the last previous issue.
