Designation:B 329–98(Reapproved 2003)
Standard Test Method for
Apparent Density of Metal Powders and Compounds Using
the Scott Volumeter
This standard is issued under the fixed designation B 329; 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 (e) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
