Foreword

This standard was drafted in accordance with GB/T 1.1-2009 given rules. Instead of the standard YS/T 44-1992 "high purity tin", compared with the YS/T 44-1992, this standard main changes are as follows. --- New Grades Sn-07. --- Increase product specifications. rod. --- Increasing the Sn-06 grades of Sb, Bi, As, Pb and In testing, Sb, Bi, As, Pb limit of 0.05 × 10-6, In the limit Value of 0.02 × 10-6. --- The Sn-05 grades of Sb is adjusted by a 0.5 × 10-6 0.3 × 10-6, As adjusted by the 1.0 × 10-6 to 0.5 × 10-6. This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized. This standard is drafted by. Zhuzhou Smelter Group Co., Ltd. The main drafters of this standard. Tan Yi-Wen, Jin Zhihong, Jian Edmonton Allen. This standard replaces the standards previously issued as follows. --- YS/T 44-1992. High-purity tin
