GB/T 223.60-1997 Methods for chemical analysis of iron, steel and alloy--The perchloric acid dehydration gravimetric method for the determination of silicon content (English Version)
This standard specifies the determination of silicon content in iron, steel, superalloys and precision alloys by perchloric acid dehydration gravimetric method. This standard applies to the determination of 0.10% (m/m) to 6.00% (m/m) silicon content in iron, steel, superalloys and precision alloys.
