Therefore, ISO 21068, Parts 1 to 3, covers the full range of analysis from pure silicon carbide to oxidic refractory composition with low-content silicon carbide and/or nitrides. Primarily, ISO 21068, Parts 1 to 3, provides methods to distinguish between different carbon bound types like total carbon (Ctotal) and free carbon (C free ) and derives from these two the silicon carbide content.
