Foreword
This standard is in accordance with GB/T 1.1-2009 given rules drafted.
Instead of the standard YS/T 22-1992 "sodium antimonate." Compared with this standard YS/T 22-1992 main changes are as follows.
--- Abolition of the "total antimony (Sb2O3 in dollars)" requirement;
--- Added As2O3, PbO, V2O5 three indicators requirements, while the moisture content as an essential test items;
--- The Cr2O3 content of an article from "not more than 0.001%" to "not more than 0.005%"; Second grade from "no more than
0.010% "to" not more than 0.005%. "
This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized.
This standard is drafted by. Tin Mine flash-antimony industry limited liability company.
The main drafters of this standard. a single peach cloud, TURAL Wuyong Yue, Song should ball.
This standard replaces the standards previously issued as follows.
