Foreword
This standard was drafted in accordance with the rules given in GB/T 1.1-2009.
This standard replaces XB/T 101-1995 "High Rare Earth Iron Ore".
Compared with XB/T 101-1995, the main technical changes of this standard are as follows.
---Adjust the product brand to a digital brand;
---Modified the particle size of high rare earth iron ore, adjusted to be between 5mm~300mm, of which the unit mass is ≥300mm
And ≤5mm are not more than 5%;
---Added the arbitration sampling and sample preparation of the chemical composition of high rare earth iron ore in accordance with the provisions of GB/T.2007;
---Modify the packaging, marking, transportation, storage and quality certificate of high rare earth iron ore to comply with YB/T 5142.
This standard was proposed and managed by the National Rare Earth Standardization Technical Committee (SAC/TC229).
This standard was drafted. Inner Mongolia Baotou Iron and Steel Rare Earth (Group) High-Tech Co., Ltd., Baotou Rare Earth Research Institute.
The main drafters of this standard. Hao Gaohui, Xu Tao, Wang Jing, Wang Xiaoqing, Zhang Xianheng, Xie Ping.
The previous versions of the standard replaced by this standard are as follows.
---ZBD43002-1990;
---XB/T 101-1995.
