Specifies an instrumental method for the determination of specific surface area of smelter-grade aluminium by nitrogen adsorption by a single or multi-point method.

This Standard sets out an instrumental method for the determination of specific surface area (SSA) of smelter-grade alumina 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: Appendix A provides an explanation why this is the case. The Standard is applicable to aluminas having a surface area between 50 m2/g and 90 m2/g.
