In the field of materials science and microscopy, accurate and reliable methods for quantifying the microstructure of materials are crucial for ensuring their quality and performance. One such method is point counting by random manual point counting, as outlined in the ASTM E562-19e1 standard. In this blog post, we will explore the details of this standard test method, its significance, and its applications.

For any laboratory performing microstructural evaluation, having a printed copy of ASTM E562-19e1 at the microscope station is not just good practice—it is a requirement for ISO/IEC 17025 accreditation in many metallography tests. In the field of materials science and microscopy,
To comply with ASTM E562-19e1, you need: For those interested in learning more about ASTM
For each grid point, ask: “Does this point lie on the phase of interest?”
