ISO 6129:1981 Preview
Chromium ores -- Determination of hygroscopic moisture content in analytical samples -- Gravimetric method
This standard was last reviewed and confirmed in 2016. Therefore this version remains current.
The method is intended to be carried out simultaneously with the determination of other constituents of the same analytical sample so that the contents of the other constituents can be calculated on the basis of the absolutely dry ore. ISO 6129 should be read in conjunction with ISO 6629.
