Abstract

This document specifies the procedure for determining bulk, dry and grain densities as well as open porosity of a rock specimen using the immersion method and a combination of the linear method and gas pycnometry. This document is applicable to the laboratory determination of density and open porosity of a rock test specimen within the scope of geotechnical investigations. Other methods for determining the bulk mass, grain mass, bulk volume and grain volume of the specimen that fulfil the requirements set in this document may also be considered acceptable (Annex B). Used method should be chosen based on the use case (type of specimen, availability etc.). Bulk, dry and grain density as well as open porosity are determined for the specimen as is and are dependent on fluid content, which shall be determined and reported as per ISO 16383-1.
