This document specifies the methods for: a) uninterrupted creep tests with continuous monitoring of extension; b) interrupted creep tests with periodic measurement of elongation; c) stress rupture tests where normally only the time to fracture is measured; d) a test to verify that a predetermined time can be exceeded under a given force, with the elongation or extension not necessarily being reported. NOTE A creep test can be continued until fracture has occurred or it can be stopped before fracture.
