ASTM D6172/D6172M-18

This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the
Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
Designation: D6172/D6172M − 18
Standard Test Method for
Determining the Volume of Bulk Materials Using Contours
or Cross Sections Created by Direct Operator Compilation

Using Photogrammetric Procedures
This standard is issued under the fixed designation D6172/D6172M; 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.
