Essay: ASTM E562-19 — Standard Test Method for Preparation of Soil Samples for Particle-Size Analysis and Determination of Soil Constants

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.

The ASTM E562-19 standard practice covers several key elements, including: astm e56219 pdf

• Metallurgy: Measuring retained austenite, ferrite/pearlite ratios, or carbide volume fractions.
• Ceramics: Determining porosity or second-phase content.
• Geology: Estimating mineral modal abundances.
• Quality control: Verifying heat treatment response (e.g., nodularity in ductile iron).

Field Sampling: Measurements must be taken on different fields of view. Repeatedly counting the same micrograph is not permitted by the standard. Essay: ASTM E562-19 — Standard Test Method for
