Yes. The official ASTM D4546-21 PDF includes an appendix with a reproducible data sheet for recording time, deformation, and load.

Reliable results depend on simulating field conditions as closely as possible. Small variations in dry density or initial water content can significantly alter the measured swell strain. For any high-stakes project, ensure your lab is following the latest 2021 protocols to provide the most accurate data for your design. Astm D4546-21 Pdf

A developer built 50 homes on a site with "moderate" swell clays. The geotechnical report used ASTM D4546-14 (old method) with an incorrect inundation procedure. When the 2021 standard was applied to a control sample post-construction, the swell potential was actually 7% (high hazard). The result: cracked slabs, buckled walls, and a $2M litigation settlement. The correct use of D4546-21 would have triggered deep pier foundations. Small variations in dry density or initial water
