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.
