Scope

This European Standard specifies the determination of the bulk density of granular refractory materials (grain bulk density) having a grain size greater than 2 mm, by the mercury method with vacuum. NOTE 1 This method is intended as the reference method because of its reproducibility and simplicity in use. However, mercury is known to be a hazardous substance, and therefore the determination of bulk density of granular materials can be carried out according to prEN 993-18. This standard, which defines a method by water with vacuum, is recommended for all routine purposes. Nevertheless, depending on the nature of the material tested, the two methods can give different results. NOTE 2 Under test conditions, applying a mercury pressure of 26,5 kPa, round pores with a diameter ≥ 55 μm and elongated pores with a width ≥ 27,5 μm are penetrated by mercury.
