DIN EN ISO 11461:2014-07

This International Standard specifies a method for the gravimetric determination of soil water content as a volume fraction. The determination of water content as a mass fraction is specified in ISO 11465. The method is applicable to all types of non-swelling or non-shrinking soils where coring sleeves can be used for sampling. The method is not applicable to soils where stones, tough roots or other factors prevent collection of soil cores. It can be used as a reference method (for example, for the calibration of indirect methods for determination of water content). This International Standard has been prepared by Technical Committee ISO/TC 190 "Soil quality" and has been taken over by CEN/TC 345 "Characterization of soils" without any modification. The responsible German body is NA 119-01-02-02 UA "Chemische und physikalische Verfahren" ("Chemical and physical methods") of the DIN Standards Committee Water Practice (NAW).
