Fitness-For-Service (FFS) assessment procedures for pressurized components operating in the
creep range are provided in this Part. The temperature above which creep needs to be evaluated can be
established using a Level 1 Assessment. The procedures in this Part can be used to qualify a component for
continued operation or for re-rating. A flow chart for the assessment procedures for components operating in
the creep range is shown in Figure 10.1.
