The Grid, Not the Eye: How a 100-Point Count Became the Gold Standard for Phase Volume Fractions

Conclusion

By 2019, the standard had reached a level of precision that Aris Thorne had taken for granted. astm e562-19e1

Statistical Foundation:

By repeating this process over multiple randomly selected fields, the ratio of points falling on a phase to the total number of points provides an unbiased estimate of that phase's volume fraction. Headline: The Grid, Not the Eye: How a

While modern image analysis software (like ImageJ or proprietary systems) can perform "automatic thresholding," ASTM E562 remains the primary validation method. Headline: The Grid
