ISO 11272:2017 specifies three methods for the determination of dry bulk density of soils calculated from the mass and the volume of a soil sample. The methods involve drying and weighing a soil sample, the volume of which is either known [core method (see 4.1)] or determined [excavation method (see 4.2) and clod method (see 4.4)].
Abstract
ISO 11272:2017 - Soil quality - Determination of dry bulk density
Overview
ISO 11272:2017 specifies standardized laboratory and field procedures to determine the of soils. The standard defines three primary methods - the , , and - all based on measuring the oven‑dry mass of a soil sample and the sample volume. Dry bulk density is a fundamental soil property used to calculate solids content, porosity and to convert concentrations between mass/volume and mass/mass.
