标准范围

该方法基于通过使用铸造程序（使用硼酸锂或硼酸钠作为助焊剂），通过熔融将铁矿石样品的试验部分加入到硼酸盐玻璃圆盘中，从而制备圆盘。它被设计用于处理具有高点火损失的铁矿石，使用经损失校正的矩阵系数。光盘的X射线荧光测量基于“仅直线”原理。资料性附录H给出了计算结果的计算机程序。

The method is based on preparation of discs by incorporating the test portion of the iron ore sample via fusion into a borate glass disc using a casting procedure (using lithium borate or sodium borate as the flux). It has been designed to cope with iron ores having high ignition losses, using loss-corrected matrix coefficients. X-ray fluorescence measurements of the discs are based on the "line only" principle. Informative Annex H gives computer programs for calculation of the results.
