supplied on any of those parts in order to retain qualification for those parts in the corresponding right
hand column.
2/ Corrosion and contact resistance test data must be submitted to DSCC-VQ before qualification
approval may be granted.
NOTE: If a connector manufacturer produces a connector which meets all the requirements for two or
more connector PINs (within the same series), the manufacturer may receive qualification approval for
two or more connector PINs by qualifying the one connector. It is not necessary that such connectors be
in the same group. Each connector, however, must be marked with its own appropriate PIN. For group
qualification, the connectors must be of similar design. Qualification of connectors qualifies connectors of
the same material and finish only.
