CSN EN ISO 8840 This document specifies three methods for the determination of the bulk density of granular refractory materials (grain density) having a grain size larger than 2 mm: - Method 1: mercury method with vacuum; - Method 2: arrested water absorption method; - Method 3: vacuum method with spin dryer option according to ISO 5017. Method 1 is intended as the reference method. The same method can be used for the determination of the volume of the sample, for selecting and preparing the sample, for calculating the bulk density and for presenting the test report.
