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.
