1、Designation:D397797(Reapproved 2013)1Standard Test Methods forDetermining Sediment Concentration in Water Samples1This standard is issued under the fixed designation D3977;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of l
2、ast revision.A number in parentheses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1NOTEEditorial corrections made to Table 1 in January 2014.1.Scope1.1 These test methods cover the determination of sedimentconcentrati
3、ons in water and wastewater samples collected fromlakes,reservoirs,ponds,streams,and other water bodies.Inlakes and other quiescent-water bodies,concentrations ofsediment in samples are nearly equal to concentrations atsampling points;in most instances,sample concentrations arenot strongly influence
4、d by collection techniques.In rivers andother flowing-water bodies,concentrations of sediment insamples depend upon the manner in which the samples arecollected.Concentrations in isokinetically-collected samplescan be multiplied by water discharges to obtain sedimentdischarges in the vicinity of the
5、 sampling points.1.2 The procedures given in these test methods are used bytheAgricultural Research Service,Geological Survey,NationalResources Conservation Service,Bureau of Reclamation,andother agencies responsible for studying water bodies.Thesetest methods are adapted from a laboratory-procedure
6、 manual2and a quality-assurance plan.31.3 These test methods include:SectionsTest Method AEvaporation8 to 13Test Method BFiltration14 to 19Test Method CWet-sieving-filtration20 to 251.4 Test Method A can be used only on sediments that settlewithin the allotted storage time of the samples which usual
7、lyranges from a few days to a few weeks.A correction factormust be applied if dissolved-solids concentration exceedsabout 10%of the sediment concentration.1.5 Test Method B can be used only on samples containingsand concentrations less than about 10 000 ppm and clayconcentrations less than about 200
8、 ppm.The sediment need notbe settleable because filters are used to separate water from thesediment.Correction factors for dissolved solids are notrequired.1.6 Test Method C can be used if two concentration valuesare required:one for sand-size particles and one for thecombination of silt and clay-si
9、ze particles.The silt-clay frac-tion need not be settleable.1.7 These test methods must not be confused with turbiditymeasurements discussed in Test Method D1889.Turbidity isthe optical property of a sample that causes light rays to bescattered and absorbed;it is not an accurate measure of themass o
10、r concentration of sediment in the sample.1.8 These test methods contain some procedures similar tothose in Test Methods D1888 which pertains to measuringparticulate and dissolved matter in water.1.9 The values stated in SI units are to be regarded asstandard.No other units of measurement are includ
