Aris took the sample to the makeshift lab. She pulled out a gridded eyepiece for her microscope—a relic from an older age. No AI. No quantum sensors. Just a human eye, a grid, and a standard.
ASTM E562-19e1 refers to the Standard Test Method for Determining Volume Fraction by Systematic Manual Point Count astm e562-19e1
), manual point counting remains the "gold standard" for calibrating these systems and providing accurate results in complex microstructures where software may struggle to distinguish between similar-looking phases. Industrial Applications Aris took the sample to the makeshift lab
The standard relies on a grid-based approach rather than subjective estimation. astm e562-19e1
