Scope

This Standard specifies two methods for the determination of the bulk density
of granular refractory materials (grain density) with a grain size of larger than
2mm.
— Method 1. Weighing method;
— Method 2. Burette method.
Method 1 is intended as the referee method.
Depending on the nature of the material tested, the two methods may give
different results. Any statement of the value of a bulk density shall therefore be
accompanied by an indication of the method used or to be used in case of
dispute. The same method shall 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.
This Standard is applicable to the determination of the bulk density, water
absorption and apparent porosity of granular refractory materials.
