Metallic materials. Uniaxial creep testing in tension. Method of test
Published By | Publication Date | Number of Pages |
BSI | 2018 | 62 |
This document specifies the methods for
-
uninterrupted creep tests with continuous monitoring of extension,
-
interrupted creep tests with periodic measurement of elongation,
-
stress rupture tests where normally only the time to fracture is measured,
-
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.
