T/CSTM 00799-2023 Active

Scope: This document specifies the grain statistics, analysis, and size determination based on high-temperature laser confocal microscopy, including terms and definitions, method principles, test methods, grain size calculation, and inspection reports. This document is applicable to grain size measurement in steel, including maximum size, minimum size, and average size. Nickel-based and other metal materials can refer to this document for implementation. The methods specified in this document are recommended methods and are not intended as standards for determining the grain size of steel or other metal materials as acceptable.
