Hereunder are the most commonly conducted tests following the different norms :

Oxidation : ASTM C 863 Norm "Assessment of resistance to oxidation at a high temperature for Silicon Carbide refractories".

Chemical analysis : measured by fluorescence XRF fused east bead.

Bulk density, apparent porosity : NFB 40-321 Norm "Establishing a bulk density of apparent porosity and true porosity"

Cold crushing strength, NF B40-33 Norm "Establishing of crushing strength of dense shaped products"

Softening under load : NF B 40-33 Norm : part 8 "Refractory products - Establishing of softening under load"

Thermal conductivity : ASTM C202 "Thermal conductivity of refractory bricks" NF B 40-303

Thermal expansion : NF B40-308 Norm "Refractory products - thermal expansion.
