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.

NOTE This document fulfils the requirements of the determination of bulk density of rock for geotechnical investigation and testing in accordance with EN 1997-2 (2024).

This document describes the basic requirements for the verification of ultimate and serviceability limit states and the resistance to fatigue either of the noise barrier or its components by means of analytical methods and/or tests. Analytical methods can be used for the determination of the characteristic values and design values. Where sufficient information is not available, the analytical procedure can be combined with results from tests. This document provides the following types of test procedures: - test on small samples for defining detail categories, which might not be covered by Eurocodes (verification procedure A); - test on a global element for defining the limit state against fatigue (verification procedure B); - full scale tests under a given representative loading (verification procedure C) to determine fatigue resistance of the noise barrier components for defined loading conditions; verification procedure C is given as alternative to verification procedures A and B.
