New!: Astm E562-19e1

The version in question, , is the "Standard Test Method for Determining Volume Fraction by Systematic Manual Point Count." The "e1" designation signifies a small but crucial editorial update—a refinement of language, a tightening of the screws to ensure that a lab in Germany and a lab in Ohio counted the exact same way.

When high-contrast images are available, allowing for much faster processing of large datasets. astm e562-19e1

The grid intersection falls entirely outside the targeted phase. The version in question, , is the "Standard

$P_P = \frac\textNumber of hits\textTotal number of points$ $P_P = \frac\textNumber of hits\textTotal number of points$

is the standard test method for determining the volume fraction of a distinguishable constituent or phase in a microstructure using a systematic manual point count . Regulated by ASTM International , this specific revision ("19e1" designating the 2019 edition with its first editorial amendment) provides metallurgists, quality control engineers, and material scientists with a statistically robust, reproducible, and cost-effective manual framework to quantify phase distributions in metals, composites, and minerals without relying on advanced automated image software.
