Abstract

The temperatures are arbitrarily selected and specified because there is no specific calcination temperature. There is no criterion for the state of calcination. Therefore, ignition of two test portions taken from the same sample and previously dried in a muffle furnace for 2 h. Calculation by difference in mass. Replaces ISO Recommendation R 806/1968.
