6.6 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.
Environmentally 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 the materials on the list should
be minimized or eliminated unless needed to meet the requirements specified herein (see section 3).
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 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. Conformance 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 3.3.6). For additional information on this matter, refer to
ASTM-B545 (Standard Specification for Electrodeposited Coatings of Tin).
6.8 Changes from previous issue. The margins of this specification are marked with vertical line to indicate
modifications generated by this revision. 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.
