I think if I had a relay that
closed at 5.9ms sitting on my
bench, I certainly would not
guarantee it to close at 6ms
during 10G's of 55-2000hz
vibration, (Kilovac specs).
This is a MIL-SPEC item and no
manufacturer would claim a max
closure speed without some
sort of safety margin, lives
could at stake. Most relay
manufacturers today are
listing max closure time and
mean closure time, usually
50-65% less time for the mean.
I've spoken to several hams
that have found the exact same
results as I have. Since you
are the only person (I know
of) that has found these long
closure times, I suggest that
your data is out of date or
corrupt.
