Abstract
Appropriate methods of testing are a key element in the prevention of hydrogen embrittlement (HE) of high performance metals in energy systems in gaseous hydrogen environments. A range of test methods, which are based on monotonic loading, is available to screen out materials which are susceptible to HE and to quantitatively predict long-term service behavior. This chapter describes some of these methods, including those of nano-mechanical testing, and comments on their advantages and disadvantages. An outlook is given regarding new developments of HE testing.
