Revision of E381-20 Standard Method of Macroetch Testing Steel Bars, Billets, Blooms, and Forgings

Rationale

Chemical segregation is inherent in steel ingots and continuous cast blooms. Macro etching can reveal this segregation, but such segregation should not be considered a ratable condition via the S-R-C reference plates. While this is implied in the current version of E381 it is not explicit. This ballot seeks to correct that oversight. Detailed discussion and justification for this change is provided in the attached supplement which in NOT to be included in the proposed revision.
