ASTM E139-00

Standard Test Methods for Conducting Creep, Creep-Rupture, and Stress-Rupture Tests of Metallic Materials

SCOPE
1.1 These test methods cover the determination of the amount of deformation as a function of time (creep test) and the measurement of the time for fracture to occur when sufficient load is present (rupture test) for materials when under con- stant tension loads at constant temperature. It also includes the essential requirements for testing equipment. For information of assistance in determining the desirable number and duration of tests, reference should be made to Section 9.  
1.2 These test methods list the information which should be included in reports of tests. The intention is to ensure that all useful and readily available information is transmitted to interested parties. Reports receive special attention for the following reasons: ( ) results from different, recognized procedures vary significantly; therefore, identification of methods used is important; ( ) later studies to establish important variables are often hampered by the lack of detailed information in published reports; ( ) the nature of prolonged tests often makes retest impractical, and at the same time makes difficult remaining within the recommended variations of some controlled variables. A detailed report permits transmittal of test results without implying a degree of control which was not achieved.  
1.3 Tests on notched specimens are not included. These tests are given in Practice E 292.  
1.4 Tests under conditions of rapid heating or short times are not included. Practices for such tests are given in Practice E21 and Practice E150.  
1.5 The values stated in inch-pound units are to be regarded as the standard.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
