The second approach is based on the allowable stress design format, where the allowable operating pressure is determined from the capacity and multiplied with a single usage factor based on the original design factor.

RP-F includes recommendations for the assessment of: Uncertainties associated with f110 sizing of the defect and the specification of the material properties are specifically considered in determination of the allowable operating pressure.
