3.6.8 Elastomeric materials. Elastomeric components shall be fabricated
from materials having maximum practicable ozone and aging resistance
consistent with performance requirements.
3.5.9 Selection of materials, processes and parts. Selection of
materials, processes and parts shall be in accordance with documents listed in
MIL-BUL-544. Materials, processes or parts not listed in these documents
shall be considered as nonstandard items. Standard components listed on the
appl icable Qualified Products List (QPL) shall be used whenever possible.
components not listed on QPLs are considered as nonstandard units, and shall
be used only when standard components are not suitable for the design
application, and when specifically approved by the acquiring activity.
Selection of parts shall be conducted in accordance with MIL-STD-965.
3.6.10 Moisture and funqus resistance. Materials in compliance with
MIL-STD-454, Requirement 4 shall be used which shall resist damage from
moisture and fungus. Protective coatings shall not be acceptable as moisture
and fungus preventatives on parts which lose the coating during the normal
course of inspection, maintenance, periodic tests, and normal operations.
