Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
Instead of the standard YS/T 300-2008 "germanium concentrate."
Compared with this standard YS/T 300-2008, the following main changes.
--- Revised Table 1 Hydrochloric acid insoluble germanium germanium proportion of the total, As, SiO2, S and burn reduction requirements 600 ℃;
--- Table 2 by the other raw materials to produce germanium concentrate grade by the nine adjusted to 6;
--- Table 2 reduction requirements increase burn 600 ℃;
Chapter 3 --- increased water requirements;
--- The original "3.3 Other germanium concentrate - such as those containing radioactive material shall conform to the provisions on radioactivity protection" to "release 3.4
Radioactive germanium concentrate as containing radioactive substances, radioactivity shall comply with the provisions of GB 20664 ";
--- Chapter 4 increased 600 ℃ burn test method reduction, water and radioactive;
--- 5.4 "at a depth of more than 3/4" with "sampling depth to the bottom";
--- 5.5 "determine whether the product is defective." Changed to "determine whether the product is defective, you can downgrade."
This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) and focal points.
This standard was drafted. Yunnan Lincang Xinyuan Germanium Industry Co., Ltd., Nanjing Germanium Technology Co., Ltd. Xilin Gol KONE germanium
Industry limited liability company, Lingnan Shaoguan smelter.
The main drafters of this standard. universal Kun, East Bowen, Liu Xinjun, Wang Xiaohua, Wang Jian.
This standard replaces the standards previously issued as follows.
--- ZBH31003-1987;
--- YS/T 300-1994;
--- YS/T 300-2008.
