Crack growth rate properties are used to assess life and integrity to determine appropriate operating conditions and service life; permissible flaw sizes; and defining minimum detectable flaw size requirements for non-destructive evaluations (NDE). In corrosion-fatigue environments, it is important to characterize the corrosion-fatigue crack growth behavior at a frequency that allows maximum interaction between the material and the environment to ensure that test conditions are suitably representative of service conditions and appropriately conservative.

A crucial step in qualifying a material for use in a critical engineering application in oil and gas production is quantifying the effect of test frequency on the FCGRs of the material in a representative environment.
