ASTM E562-19 is a standard published by ASTM International that specifies procedures for preparing soil samples for particle-size analysis and for determining soil constants used in geotechnical engineering and soil science. First issued in earlier editions and updated in the 2019 revision (hence “-19”), this standard covers methods to obtain representative, reproducible, and well-documented soil samples from bulk material and to reduce samples to sizes appropriate for laboratory testing while minimizing alteration of particle-size distribution, moisture condition, and other key properties.
Purpose: To provide a statistically valid estimate of the volume fraction of an identifiable phase or constituent in a metallographic specimen.

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.
The applications of ASTM E562:19 are diverse and span multiple industries: Input Form : A simple input form for
Step 1: Specimen Preparation The metallographic sample must be cut, mounted, ground, and polished to a scratch-free finish. Etching is required to reveal the phases of interest.
