It is normal to put notches ID & OD on the actual part for this type of inspection rather than make a special cal. block.

Your specification/procedure should be consulted.

Your stansard call for 2mm flat bottom hole of side drill hole ? in eithe case you need
reference block to set up sensitivity.

Subject line of posting is Shear Wave. FBH's are almost always for straight beam. SDH's are normally used for weld inspections.
Notches are used for angle beam examinations of various product forms including large forged rings like you describe. Unless you have additional material to make a cal block from it is common to put the notches in the actual product and if necessary machine them off after testing.
