6.3 Approving activity. Information pertaining to first article inspection and approval of products covered by this
specification should be obtained from the acquiring activity.
6.4 Tin whiskers. 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 3.4.4). For additional information on this matter, refer to ASTM-B545
(Standard Specification for Electrodeposited Coatings of Tin).
6.5 Subject term (key word) listing:
Communication
Polarization
Frequency
Radiation
Impedance
Seal
Nonflammable
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 Changes from previous issue. Marginal notations are not used in this revision to identify changes with respect
to the previous issue, due to the extensiveness of the changes.
