2、ase of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This guide covers the selection of methods for deter-mining the size distribution of fluv
3、ial sediments particles in therange greater than 0.45 m using manual methods. Manualmethods are defined as those methods that require the operatorto do some actual measurements and calculations. An auto-mated method would be one which, after the sample isprepared and inserted into an instrument, the
4、 instrument(machine) does the measuring and calculations, not the opera-tor. Not all manual methods are presented in this guide.However, where available, at least two methods for eachparticle size range are given.1.2 The values stated in SI units are to be regarded asstandard. No other units of meas

It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory lim

Significance and Use5.1 This guide is general and useful in helping the user todetermine an appropriate manual test method for determiningthe particle size distribution of fluvial sediments. The sug-gested test methods are not described in this
11、guide, butreferences are given so that the user may obtain more infor-mation about each test method.5.2 It should be noted that different test methods may andoften times do produce different particle size distributions forthe same sample. This is due in part to the different testmethods requiring na
