BS 6870-2.2:1987

This standard BS 6870-2.2:1987 Analysis of aluminium ores. Chemical methods is classified in these ICS categories:

• 73.060.40 Aluminium ores

This International Standard specifies a gravimetric loss of mass method for the determination of hygroscopic moisture in analytical samples of aluminium ores.

The method is applicable to products having hygroscopic moisture contents, expressed as water (H₂O), in the range 0,1 to 5 % (m/m), and shall be used to correct the results obtained for aluminium and loss of mass at 1 075 °C to a dry basis.

NOTE The hygroscopic moisture can be taken into account for other determinations by using a pre-dried sample prepared in accordance with ISO 8558.

Applicable to moisture contents, expressed as water (H₂O), in the range 0.1% to 5% (m/m).
