ASTM E562-19
The standard outlines a systematic manual point counting procedure to statistically estimate the volume fraction of a specific phase or constituent within a material's microstructure. This method is primarily used in metallurgy to quantify components like ferrite or pearlite in steel. Core Procedure Summary
- Sample identification number
- Number of samples collected
- Sample characteristics (e.g., temperature, pressure)
