Such tests are usually required for heavy wall thickness (>40 mm) when the steel plate or section is used in construction with joints/nodes with very high utilization of the steel out-of-plane. For example for plates or beams, where lifting lugs are welded to. But it may also be relevant to many other joints, depending on the structural design (and design calculations).
Otherwise, if only lamination may be the problem (and for plates betwenn 6 mm and 40 mm thickness, requiring "z-properties", lamination checks are carried out by ultrasonic scanning according to EN 10160.

Subject: [MW:10158] Re: THROUGH THICKNESS DUCTILE TESTING
Dear Manoj,
This requirement should be taken in account when purchasing steel plates. Executing a normalizing heat treatment afterwards on rejected plates will normalize your material structure but mostly not dissolve the present manganese sulphite inclusions which often causes not satisfying the required % RA. So in such case in my opinion you need to order new material with the required Z quality mentioned in your purchase order.
Best Regards,
Herman Pieper
