Foreword
Instead of the standard YS/T 524-2006 "synthetic scheelite technical conditions."
This standard YS/T 524-2006 compared to the main changes are as follows.
--- Synthetic scheelite grade consists of six adjusted to 8;
--- Chemical composition made appropriate adjustments;
--- Test methods and inspection rules have been modified.
This standard by the national non-ferrous metals Standardization Technical Committee (SAC/TC243) centralized.
This standard was drafted. Ganzhou Nonferrous Metallurgy Research Institute.
The main drafters of this standard. Pan Jianzhong, Liu Bolu, Wang Linsheng, pipe Jianhong Wu Siping, Xieshi Yong, Tian Yonghong.
This standard replaces the standards previously issued as follows.
--- GB/T 5192-1985, YS/T 524-2006.
Synthetic scheelite
1 Scope
This standard specifies requirements for synthetic scheelite, test methods, inspection rules, marking, packaging, transportation, storage, quality certificate and contract (or
Orders) content.
This standard applies to income by smelting synthetic scheelite product (also known as calcium tungstate), for the production of ammonium paratungstate, tungsten trioxide, tungsten, iron, hard alloy
Gold, steel, tungsten, tungsten alloys and other materials to use.
