Aluminium and aluminium alloys -- Determination of silicon -- Gravimetric method
This standard was last reviewed and confirmed in 2017. Therefore this version remains current.
The method is applicable to the determination of silicon content greater than or equal to 0,30 % in aluminium and aluminium alloys. The method is not completely applicable to alloys containing silicon or magnesium (see annex A) and tin or antimony respectively (see annex B), for which it should be modified.
