The index “Mass fraction of total moisture” is not a reject; it serves for calculation of the weight of a lot of blast-furnace coke being delivered to the Consumer as dry matter.

The index “Volatile-matter yield” is not a reject and serves as the additional characteristic of blast-furnace coke.

Strength index M40 is not a reject being determined at the Consumer’s request stipulated in the Product Delivery Contract.

The strength indices of blast-furnace coke meant for export are permitted to be determined according to GOST 8929.
