Selection of standards and Specifications -
Standards
and
specifications for necessary commodities and services not specified herein
shall be selected in accordance with MIL-STD-143.

Materials
3.4.1 Fungus-proof Materials - Materials that are nutrients for fungi shall
not be used where it is practical to avoid them.
Where used and not
hermetically sealed, they shall be treated with a fungicidal agent acceptable
to the procuring activity. If used within a hermetically sealed enclosure,
fungicidal treatment shall not be required.
3.4.2 Metals - Metals shall be of the corrosion-resistant type or shall be
suitably treated to resist corrosion due to conditions likely to be
encountered in storage or normal service.
3.4.2.1 Dissimilar Metals - Unless suitably protected against electrolytic
corrosion, dissimilar metals shall not be used in intimate contact with each
other. Dissimilar metals are defined in MIL-STD-889.
3.4.3 Non-magnetic Materials - Non-magnetic materials shall be used for all
parts of the control assembly except where magnetic materials are essential.
3.4.4 Corrosive Fumes - Materials, as installed and used in the control
assembly and under the service conditions specified herein, shall not
liberate deleterious fumes.
3.4.5 Protective Treatment - When materials are used in the construction of
the control assembly that are subject to deterioration when exposed to
climatic and environmental conditions likely to occur during service usage,
they shall be protected against such deterioration in a manner that will in
no way prevent compliance with the requirements of this specification. The
use of any protective coating which will crack, chip, or scale with age or
extremes of climatic and environmental conditions shall be avoided.
3.5 Design and Construction - The control assembly shall be designed to
accept and provide input and output signals as specified herein, and shall be
so constructed as to withstand the strains, jars, vibrations, and other
conditions incident to shipping,
storage,
installation, and service.
