ASTM E562-19 standard outlines a systematic manual point-counting procedure for estimating the volume fraction of an identifiable constituent or phase within a material's microstructure. ASTM International Core Procedure Guide Sample Preparation Prepare polished metallographic specimens according to : Use light etching (e.g., shallow microetching per

Significance of ASTM E562-19

Coating thickness is a critical parameter in many industrial applications. For instance, in the aerospace and automotive industries, coatings are used to protect components from corrosion and wear. Inadequate coating thickness can lead to premature failure, safety risks, and costly repairs. Similarly, in the construction industry, coating thickness affects the durability and aesthetic appeal of buildings. Therefore, accurate and continuous coating thickness measurements are essential to ensure product quality, reliability, and performance. astm e56219 pdf

Data Export and Management: The feature will enable users to export the report in various formats (e.g., PDF, CSV, Excel) and manage sampling data for future reference.

• Quartering (coning and quartering) for larger bulk samples, performed on a flat, clean surface after forming a conical pile, flattening, dividing into quarters, and recombining appropriate quarters to reduce sample size.
• Mechanical sample splitters (riffle or rotary splitters) for dry, free-flowing granular soils; guidelines cover splitter design, number of divisions, and procedures to avoid segregation and bias.
• Riffling limitations: For moist, sticky, or cohesive soils that can bridge or smear in splitters, the standard recommends alternative methods (e.g., quartering after partial drying or use of spatulas/scoops).
• Hand reduction and spatula techniques for very small required masses or for delicate materials where mechanical splitting could alter particle-size distribution.

• Aerospace: Measuring volume fraction of alpha/beta in titanium alloys (AMS standards point to E562).
• Automotive: Nodularity in ductile iron and percentage of martensite in dual-phase steels.
• Power Generation: Graphite morphology in reactor components.
• Medical Implants: Porosity fraction in additive manufactured (3D printed) titanium.

Magnification: The magnification should be set so that the features of interest are approximately half the size of the grid spacing to ensure accuracy. Why Use This Method? performed on a flat
