Note:
Nominal specs represent the design specs: all units should be able
to
approximate these - some
wiJl
ex-
ceed and
some
may
drop
slightly below these specs. Limit specs represent the absolute worst condition that still
might be considered acceptable; in
no
case should a unit perform
to
less than
any
limit spec.
