ASTM D4220/D4220M-14 PDF Download

ASTM D4220/D4220M-14 standard provides procedures for preserving soil samples obtained in the field and instructions for their transportation and handling. These practices aim to ensure that the integrity of the soil samples is maintained throughout the preservation and transportation process.

The standard acknowledges that it does not address requirements specific to soil samples containing hazardous materials. It highlights the use of the gravitational system of inch-pound units when dealing with inch-pound units, distinguishing between force (weight) represented by pounds (lbf) and mass represented by slugs.

It's important to note that this standard should be used in conjunction with professional judgment and should not replace education or experience. Not all aspects of the standard may be applicable in every circumstance, and it does not replace the standard of care for professional services. The term "Standard" in the title only indicates that the document has been approved through the ASTM consensus process.
