UT-388 accetpance standard as per ASME Sec VII Div-1

Can any one suggest if i performed UT of base material (forging) as per SA 388 [straight beam technique+Angle beam technique]
what is the acceptance level

a) as per S20 of SA 788
or
b) as per Apprndix - 12 of Div-1 (I think this is applicable for welds)

dpja,
Acceptance standard is clearly defined in S20 review again.
It further supports with S20.2.8 Additional nondestructive examination or trepanning may be employed to resolve questions of interpretation of ultrasonic indications. The manufacturer shall accept responsibility for injurious conditions which will not be removed in final machining.
There is no question of your thinking on Appendix 12, it clearly states "This Appendix describes methods which shall be employed when ultrasonic examination of welds is specified in this Division."
Homework will increase awareness.
