ASTM D8263/D8263M-23

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: D8263/D8263M − 23
Standard Test Method for
Determining the Change in Mass of Rolled Erosion Control
Products When Submerged in Water
This standard is issued under the fixed designation D8263/D8263M; 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.
