Reference Sensitivity for fusion plus weld test of T joints

What is the reference sensitivity required for 0° probe, when testing the fusion zone (and weld) of Full Penetration Joints from main member side?

Whether Lamination test sensitivity (2nd back wall echo at 80% etc) is acceptable or we need to make a DAC suind SDH? Consider the following codes:

Case 1: According to ABS Guide
