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

es place circumferentially or “around the curve” for applications such as inspection of longseam welds in piping and vessels. Jointly designed by PH Tool and Holloway NDT, the blocks feature side-drilled hole reflectors positioned within novel compound-curves, each with multiple thickness steps. The unique design results in a light and compact form factor, with the largest block weighing just over 15 lbs and spanning just 16 ¾”. Coverage is provided for nominal pipe sizes from 6” to 10” in the small block and 12” to a whopping 56” in the large block. The compound OD curves and multiple wall thicknesses actually exceed ASME requirements, providing exceptional signal response and measurement accuracy. Properly managing beam divergence off the ID and stabilizing beam skew due to probe rocking is essential to maintaining a consistent calibration when inspecting lengthwise on curved surfaces.
