Scope

This standard specifies the method for the preparation of pre-dried samples of bauxite ore. This standard is applicable to the determination of the content of certain components in bauxite ore calculated on a dry basis. Note: When the analysis element calculated on a dry basis in bauxite ore is aluminum or the mass loss is measured at 1.075°C, it shall be carried out in accordance with the provisions of GB/T 3257.24.
