1、Designation: D 4822 88 (Reapproved 2003)Standard Guide forSelection of Methods of Particle Size Analysis of FluvialSediments (Manual Methods)1This standard is issued under the fixed designation D 4822; the number immediately following the designation indicates the year oforiginal adoption or, in the
2、 case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) 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 f
3、luvial 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,
4、the 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 This standard does not purport to address all of thesafety concerns, if any, ass

Summary of Guide4.1 This guide consists of suggested manual test methodsfor analyzing fluvial sediment samples for particle size distri-bution.5. Significance and Use5.1 This guide is general and useful in helpin
10、g 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 guide, butreferences are given so that the user may obtain more infor-mation about each test method.5.2 It should be note
11、d 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 native or distilled water, differences indispersion methods used, and differences in what the testmethod is measuring, that
