Aluminium oxide primarily used for the production of aluminium. Determination of specific surface area by nitrogen adsorption Ingestion-build-61878 Tolerances on width for cold-rolled1 Scope This International Standard specifies an instrumental method for the determination of specific surface area (SSA) of smelter grade alumina (SGA) by nitrogen adsorption by a single or multi point method. A multi point method is recommended due to the higher accuracy obtained; if a single point method is used, a lower result will be obtained. NOTE Annex A provides an explanation of the difference between single and multi point determined BET
