This International Standard specifies a method for the gravimetric determination of the water content of soil as a volume fraction. This method can be applied to all types of non-swelling soils that can be sampled with sampling cylinders. The method is not applicable to soil with stones, strong roots or other influences that prevent the collection of soil cores. It can be used as a reference method (e.g. for calibrating indirect methods for determining water content). NOTE The determination of water content as a mass fraction is specified in ISO 11465.
