This part of ISO 21068 specifies methods for the determination of total nitrogen and nitrogen calculated as
silicon nitride, total oxygen, and free metallic and oxidic components in silicon carbide raw materials and
refractory products.
It applies only to silicon carbide materials that are not bonded with nitrogen. Nitride-bonded silicon carbide
refractories are covered in EN 12698-1.
