Determining the bulk density according to DIN EN ISO 17892-3

Status: 10.12.2024

The grain density, formerly known as specific weight, is defined as the dry mass of the individual solid components of the soil in relation to the volume of the individual components.

The volume of the grains is determined in a capillary pycnometer with a known volume. The grains are filled in, and the remaining volume is measured with distilled water. The density of the water must be known for evaluation. It depends on the temperature.

The grain density serves as an auxiliary value, e.g. for determining the pore proportion, the shrinkage limit and the grain size distribution through sedimentation analysis and for evaluating the Proctor test.
