Says nothing, Guy,

they must specify shock waveform and time, and vibration waveform and
frequency range. There are tiny accelerators that you can put on the relays
and connect to a data recorder that follows the band through the washer.
Must be a hell of machine to create such impacts. PLace one accelerator to
the moving holder, whatever that is. As a reference.

What kind of relays?  And how are they mounted?  Do you clean them as free
individuals or are they soldered to a board?  I have shocked and vibrated
all kind of electronics long time back. Never, never heard of such things
as what you tell us.
