Creep / Stress Rupture of Metallic Materials ASTM E 139

ASTM E139 - Standard Test Method for Conducting Creep, Creep-Rupture, and Stress-Rupture Tests of Metallic Materials

The method, ASTM E139, determines 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 constant tension loads at constant temperature. It also describes the essential requirements for testing equipment.

Rupture tests, properly interpreted, provide a measure of the ultimate load-carrying ability of a material as a function of time. Creep tests measure the load-carrying ability for limited deformations. The two tests supplement each other in defining the load-carrying ability of a material.

In selecting the material for a particular elevated temperature application, the type of test data used will depend on the load carrying needs of the design.

Touchstone engineers can provide testing to ASTM E139, the design of the test plan, and assistance in determining what data might be most helpful for a particular design.
