If your project specification or building code references ASTM D4546-21, you must use the 2021 edition. A PDF from 2014 or 2008 will not satisfy the requirement.
The ASTM D4546-21 test method provides a standardized procedure for determining the withdrawal or pullout strength of anchors in soil or rock. By following this guide, users can ensure that the test is conducted properly, and the results are reliable and accurate. Astm D4546-21 Pdf
a specimen has already undergone wetting-induced deformation from Method A or B. This simulates scenarios where additional structural loads or new fills are applied to ground that has already settled or heaved due to water infiltration.

Measures the amount of vertical strain (percent swell) that occurs when a specimen is inundated under a specific constant pressure. By following this guide, users can ensure that
In the world of geotechnical engineering and soil mechanics, few phenomena are as destructive as unexpected soil volume change. Whether it is the heaving of a building foundation due to expansive clay or the sudden settlement of an embankment over collapsing soil, the financial and safety implications are immense.
: Measures the vertical strain (swell or settlement) under a specific vertical stress representing field conditions (e.g., overburden pressure).
Used to determine the "swell pressure"—the vertical stress required to prevent a soil specimen from swelling when it is inundated with water.
