Is pre-out the same ?

I have an integrated amp with a "pre-out" function . I want to try a
tube amp onto my SS integrated amp through this pre-out connection .
Does this "pre-out" have the same impedance requirements as a
stand alone preamp ? I believe that it is a 1 to 10 ratio of impedance from 
preamp to amp . Or , for instance , a 10k ohm impedance on the preamp out
to 100k ohm impedance for the amp-in . Correct ?

Are there any other requirements that I should consider ?

Thank you and be safe .

It will be safe.

The 10:1 ratio has more to do with the frequency response.  The higher the ratio the better, but even a 5:1 won't sound terrible or break anything.

Since you haven’t mentioned the make and model integrated you have all we can go on are general rules of thumb, like the 10:1 ratio. If there is a mismatch the specific result is a roll off of bass response, but even integrated amps’ pre-outs if they are really preamp outputs are likely to be low enough impedance to avoid that. The final point is the big one, we always say the preamp is like the first lens in an optical system, very important in setting the stage for what follows. How good a preamp is in there?  If it’s a Naim Atom, then you should be in great shape, others…your ear will tell.

Eric - thanks .

crustycoot - excellent 'guess'. Maybe not so crusty ?

Happy SAFE Tunes .
