I am new to the ASME codes and can any of you please guide me what is the difference between Appendix 4 of Division 1, Appendix 8 of Division 2 and Appendix 6 of Division 3 of ASME Sec. VIII.

Having not been involved in Div 2 and 3 vessels I would venture a guess that the requirements are more stringent when concerned with high pressures (Div 3) or more sophisticated calculations to reduce wall thickness (Div 2).

I can tell you that the Div 1 Appendix 4 is the Round indication charts for RT acceptance. As far as the other two Divisions, sorry I don't have them but I would assume they are applicable to what each division accepts for round indications.
