ASTM E562-19e1 is a powerful, detailed, and flexible standard for characterizing materials. By providing a systematic and statistically sound method for manual point counting, it empowers metallurgists, materials scientists, and quality control engineers to obtain reliable volume fraction data across a wide range of materials and applications. Whether used as a primary tool or a complementary technique to automated analysis, it remains a cornerstone of modern quantitative metallography.

High; minor shading or etching variations cause thresholding errors.
