ASTM D1739-98(2017)

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: D1739 − 98 (Reapproved 2017)
Standard Test Method for
Collection and Measurement of Dustfall (Settleable
Particulate Matter)
This standard is issued under the fixed designation D1739; 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.

weatherproof plastic. They shall be capable of accepting

lid is needed for each container.

container at a height of 2 m above ground. It will also include
a wind shield constructed in accordance with Figs. 1 and 2.
Experiments reported in Kohler and Fleck (2) indicate that
much better precision is obtained when this simple aerody-
namic shield is provided, and that there is a wide variability in
the concentration of particles subject to settling at heights of
less than 2 m.
