6.5 Environmentally preferable material. Environmentally preferable 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).
6.6 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 (see
3.4.9.1). For additional information on this matter, refer to ASTM-B545 (Standard Specification for
Electrodeposited Coatings of Tin).
6.7 Changes from previous issue. This specification is 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.
