Designation: D6938 − 15
Standard Test Methods for
In-Place Density and Water Content of Soil and Soil-
Aggregate by Nuclear Methods (Shallow Depth)1
This standard is issued under the fixed designation D6938; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
