RE: Steel Casting Test Coupons, Differences
From my perspective, it sounds like the grated test coupon you mention is really a separate multiple (bend bar) keel block test coupon, and the integral cast test coupon is what it is, test coupons which are cast integrally with the castings.
Source of the above - none other than ASTM A 703 "Steel Castings, General Requirements, for Pressure-containing Parts"

Attaching a test coupon on to a casting,demands proper location of the test block in the mould. This may need larger mould boxes,also if it is not suitably attached,to the casting,casting zone near the test bar can indicate signs of porosity due to improper feeding( This is more due to poor foundry practice). From an inspector's point of view the test coupon remains attached to the casting,through it's complete process cycle and can only be separated at the stage of final inspection.
Hope, I have not complicated a simple issue.
