Foreword
This standard was drafted in accordance with GB/T 1.1-2009 given rules.
Instead of the standard YS/T 207-1994 "conductive ring with precious metal and alloy tubes."
This standard YS/T 207-1994 compared to the main changes are as follows.
--- Increasing the product tag example;
--- Increased Ag77Cu, Pt82.5Ir, Au75CuNi and Pd70Ag four alloy grades;
--- Harmful impurity elements Fe's maximum allowable content of the original standard of 0.1% revised to 0.2% ≤0.1%, the original total amount of impurities
Standard 0.3% to 0.35% revised ≤0.25%;
--- Pipe diameter increased to 40mm, wall thickness increased to 5.0mm.
This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized.
This standard by your research Platinum Ltd. is responsible for drafting.
The main drafters of this standard. Wu Xiaofei, XIA Kun, Yu-kun, Chen Teng rights, Li Jinghua, Wang Jian, Qiuhong Lian, Zhu Wuxun.
This standard replaces the standards previously issued as follows.
--- GB n71-79;
--- YS/T 207-1994.
