Union of sets of a partition not equal to the original set

Question

Is there a name for a "partition" where the union of its sets is not equal to the original set, but still disjoint?

This is just a collection of disjoint subsets. I'd be surprised if there were another name for it. — Matt Samuel, Dec 05 '19 at 16:41

You could call it the set of blocks of a partial equivalence relation.
