Calibration block for TOFD

Dear Experts,
Please clarify regarding the calibration block requirement for TOFD.

1) What is the requirement of a calibration block? Should it be of the same material as that of the test material?

2) Is there any equivalent material like base on P nos or group nos?

Relevant ASME clause may please be cited.

Thanks & Regards

Dear all,
I do not understand if you speak about calibration or validation block? In any case you must have same P-no, heat treatment condition, surface condition for both. For other difference please check into asme v art 4 for calibration and appendix ix for validation
