I do like you do when riding, and I usually save up my tubes with holes and patch a bunch of them all at once. That way I can use a tub of water to both find the holes, and can go back through them after patching and test to see if they are holding air. If I have any doubt after patching a tube, I give it a little time to cure and then I pump it up and hang ...

You have the right idea. Inflate the tube to roughly the side it is in the tyre, which will be a much lower pressure than it would be if it was in a tyre. My floor pump doesn't register the pressure of a tube pumped up like this, so I expect it's less than 10psi/1 bar.

A propperly applied patch should resist inflating the tube up to 1.5-2 times the nominal diameter. This is useful for testing the quality of the patching work but also to find the tiniest holes that sometimes are harder to spot. As other say, the definitive way to test is to inflate and submerge in water or to inflate and let overnight to see if it holds. ...

You should inflate the tube to 1.5 to 2 times the "normal" diameter, in order to develop a modicum of pressure. (Wait until after the patch has "cured" overnight to do this, however.) Then either test in a tub/sink or let it sit overnight again to see if it loses air. (Getting the tube to fold up nicely is not a problem, if it's a Presta. Just squeegee ...

My experience is that you can't fully test a patch until you take it up to full pressure. I had a patch that was fine for months at low pressure on the bike. I took the 2.10 up to full pressure to ride on the road and the patch failed. Even if you put it on the bike to test the problem is getting the fresh tube you used back in the seat bag. I only use ...
