Manganese ores and concentrates -- Determination of aluminium content -- Photometric and gravimetric methods
This standard was last reviewed and confirmed in 2016. Therefore this version remains current.
The photometric method (A) is applicable to products having aluminium contents from 0,1 to 1,5 % (m/m), the oxine gravimetric method (B) is applicable to products having aluminium contents over 1,5 % (m/m). Cancels and replaces the first edition (ISO 4295:1978), of which it constitutes a technical revision. Should be read in conjunction with ISO 4297.
