- RT1 applies when all pressure-retaining butt welds (with exceptions) have been radiographically examined for their full length according to UW-51. This will default all joints to 100% efficiency.
- RT2 applies when the complete vessel satisfies the requirements of UW-11(a)(5) and when the spot radiography requirements of UW-11(a)(5)(b) have been applied. The program defaults to 100% on heads and shell longitudinal joints and 85% on shell circumferential (girth) joints and 85% on shell longitudinal joints.
- RT3 applies when the complete vessel satisfies the spot radiography requirements of UW-11(b). The program defaults to 85% on all joints.
- RT4 applies when only part of the complete vessel satisfies the radiography requirements of UW-11(a), or where RT1, RT2, and RT3 do not apply. The program defaults to 70% efficiency on all joints when either RT4 or None is selected.
