GB/T 223.55-2008 Iron,steel and alloy—Determination of tellurium content—Oscillo-polarographic method
Abstract
This part of GB/T 223 specifies the determination of tellurium content in steel and alloys by oscillopolarography (direct) and oscillopolarography with thioglucose cotton separation.
The oscillopolarography (direct) method in this part is suitable for the determination of tellurium content in pure iron, raw cast iron, and low-alloy steel with a mass fraction of 0.001% to 0.050%; the oscillopolarography with thioglucose cotton separation method in this part is suitable for the determination of tellurium content in raw cast iron, high-, medium-, and low-alloy steel, and high-temperature alloys with a mass fraction of 0.000 04% to 0.001%.
