Thanks to Emma's attention to detail and her team's expertise in applying the ASTM E562-19 standard, they were able to ensure that the steel alloy they developed met the highest quality standards. The project was a success, and Emma's team was able to deliver a high-quality product that met the needs of their customers.

ASTM E562-19 outlines a systematic, manual point-counting procedure to accurately estimate the 3D volume fraction of microstructural phases in materials using a 2D grid overlay. The standard enables precise quantification of constituents like ferrite in steels by analyzing microscopic fields and calculating a 95% confidence interval for the result.

To achieve statistical significance, ASTM E562-19 requires counting a minimum total number of points (typically 400 to 1,000) across at least five or more random fields. The standard also provides guidelines for calculating 95% confidence intervals using the binomial distribution, ensuring the estimate's precision. Thanks to Emma's attention to detail and her
