Radiography in shell with thickness 1.25 inch

[TheEverest]

Dear all. According to table UCS-57, the nominal thickness above which full-radiography is needed is given as1.25 inch for P.no. 1 and Gr.1,2,3 material. Does this include the thickness 1.25 inch as well?

 

[XL83NL]

No. See Interpration VIII-81-102 if semantics is an issue in the translation.

 

[TheEverest]

Do you mean that full radiography is for only nominal thickness above 1.25 inch and not for 1.25 inch?

Correct.
