6.2.2 Contract data requirements. Data generated by this document are not deliverable unless specified on the
Contract Data Requirements List (DD Form 1423) or the contract schedule. The data required by this specification
include, but are not restricted to the following:
(a) Drawings (see 3.10 and 3.10.1).
(b) Test reports (see 4.5.1).
6.3 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 EPA 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).
6.4 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. For additional information on this matter, refer to ASTM-B545 (Standard
Specification for Electrodeposited Coatings of Tin).
6.5 Subject term (key word) listing.
rotary
high impact
push-pull
