A Container for Storing and Transporting Bulk Material Samples.

This article presents problems related to the storage of building material samples and discusses the related requirements and standards. Solutions for containers to store material samples were proposed and tests were performed in accordance with the EN ISO 12570 standard to demonstrate that all the water that may have condensed during the samples' transport in the self-designed, closed container evaporates from the lid when unscrewed and placed under the container during the drying process. The aim of this study was to test the tightness of self-designed containers for transporting bulk samples. The drying efficiency at elevated temperatures in moisture tests for bulk material containers was determined and, finally, the influence of ambient conditions on a sample placed in a container for bulk material transport was estimated. The results confirmed that the designed container is vapour-tight and allows the collected material to be protected against evaporation during transport from the sampling site to the laboratory. Under extreme transport conditions, the water contained in the sample in a closed container partially evaporates from the material and condenses on the lid but this is taken into account when balancing the moisture of samples in the laboratory and does not falsify the readouts.
