This document gives definitions and specifies techniques for the preparation of samples for the chemical analysis of silicon-carbide-containing raw materials and refractory products including:

a)       SiC raw materials;

b)       graphite brick containing silicon carbide;

c)        silicon carbide brick (includes the bricks containing silicon nitride, silicon oxynitride, sialon);

d)       refractories containing carbon and/or silicon carbide mixed with clay;

e)       refractories containing carbon and/or silicon carbide mixed with silica (and fused silica);

f)         refractories containing carbon and/or silicon carbide mixed with high alumina material;

g)       refractories containing carbon and/or silicon carbide mixed with magnesia (and dolomite);

h)       refractories containing carbon and/or silicon carbide mixed with chrome mineral or magnesia-chrome materials;

i)         refractories containing carbon and/or silicon carbide except those described in a) to h) above.
