You mean it the Commerce Control List (CCL) talks about "space
qualified _atomic_ frequency standards".

----------------------
<http://www.access.gpo.gov/bis/ear/pdf/ccl3.pdf>

3A002 ...

g. Atomic frequency standards having any of the following:

  g.1. Long-term stability (aging) less (better) than 1 x 10^-11/month; or
  g.2. Being "space qualified".

Note: 3A002.g.1 does not control non-"space qualified" rubidium standards.

So quartz oscillators do not fall under this category. Nevermind, that
as far as I know all HP oscillators are not space-qualified.
