Foreword

Instead of the standard YS/T 269-1994 "Sodium butyl xanthate (synthetics)", YS/T 354-1994 "butyl xanthate (dry goods)." This standard YS/T 269-1994, the main changes compared to YS/T 354-1994 as follows. --- The new standard and butyl potassium xanthate. --- This standard is based on the development butyl xanthate products, additional granular products section. --- The new standard increased the export product packaging requirements. This standard by the National Standardization Technical Committee of non-ferrous metals and centralized. This standard by the Tieling pharmaceutical processing plant responsible for drafting. The main drafters of this standard. Competitive Selection, Han Lifen, Xiao Wenge. This standard replaces the standards previously issued as follows. --- YB500-1965 (synthetic products), YB500-1976, GB/T 8148-1987, YS/T 269-1994 --- YB500-1965 (dry goods), YB869-1976, YS/T 354-1994 Butyl sodium (potassium) xanthate
