Method for detecting leakage of semipermeable membranes or hollow fibers, said membranes or fibers exhibiting salt rejection, which comprises contacting one side of the membrane or fiber with an aqueous salt solution so that purified water will pass across non-leaking members to the second side and a salt enriched aqueous solution will pass to the second side of leaking members, and measuring the salt content of the aqueous solution on the second side of the member so that leaking members can be detected.
