Standard Guide for
Selection of Methods of Particle Size Analysis of Fluvial
Sediments (Manual Methods)1

This standard is issued under the fixed designation D 4822; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of the 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.

1. Scope

1.1 This guide covers the selection of methods for determining the size distribution of fluvial sediment particles in the
range greater than 0.45 µm using manual methods. Manual
methods are defined as those methods that require the operator
to do some actual measurements and calculations. An automated method would be one in which, after the sample is
prepared and inserted into an instrument, the instrument
(machine) does the measuring and calculations, not the operator. Not all manual methods are presented in this guide.
However, where available, at least two methods for each
particle size range are given.

1.2 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.
