retain an item in, or restore it to, a state in which it can perform a required function
Note 1 to entry: There are two basic categories of maintenance: corrective maintenance done after a failure has
occurred and preventive maintenance (testing, inspection, condition monitoring, periodic) done before a failure
has occurred. See also ISO 14224[15], 9.6.
Note 2 to entry: Maintenance activities of either preventive or corrective maintenance category type, is shown in
ISO 14224:2006[15], Table B.5.
