Standard Test Method for Collection and Measurement of Dustfall (Settleable Particulate Matter)

SCOPE
1.1 This test method covers a procedure for collection of dustfall and its measurement. This test method is not appropriate for determination of the dustfall rate in small areas affected by specific sources. This test method describes determination of both water-soluble and -insoluble particulate matter.
1.2 This test method is inappropriate for industrial hygiene use except where other more specific methods are also used.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

Standard Test Method for
Collection and Measurement of Dustfall (Settleable
Particulate Matter)
This standard is issued under the fixed designation D 1739; 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.

container at a height of 2 m above ground. It will also include
a wind shield constructed according to Figs. 1 and 2. Experi-
ments reported in Kohler and Fleck (2) indicate that much
better precision is obtained when this simple aerodynamic
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.

its surroundings. Also included should be photographs or
detailed descriptions of the surrounding area in the four
compass point directions from the container stand. Unusual
activities occurring in the neighborhood of the site that emit
large amounts of particulate matter into the air should be
recorded in the site file. Such events are fires, construction and
demolition work, traffic diversions, and so forth. Records of
