This paper highlights the efforts that were undertaken within the framework of the EU FP7 ReStaR research project for the determination of testing parameters and conditions (“factors”) influencing the bulk density (BD) and open porosity (oPo) testing results of refractory materials. Besides the generation for precision data, it is necessary to understand which instructions in the standard EN ISO 1927‑6 for unshaped refractories and in the standard EN 993-1 for dense shaped refractories and carbon-bonded refractories are sensitive for diverging testing results and are therefore to be considered as significant factors influencing those results.
