　本标准共分两个部分。本部分是第１部分。本方法规定了离子型稀土矿混合稀土氧化物中十五个稀土元素氧化物配分量的测定方法。
本方法适用于离子型稀土矿混合稀土氧化物（ＴＲＥＯ≥８０％）中十五个稀土元素氧化物配分量的测定。测定范围（质量分数）：０．２０％～９９．００％。本部分是对ＧＢ／Ｔ１８８８２．２—２００２《离子型稀土矿混合稀土氧化物化学分析方法　Ｘ射线荧光光谱法测定十五个稀土元素氧化物的配分量》和ＧＢ／Ｔ１８８８２．３—２００２《离子型稀土矿混合稀土氧化物化学分析方法　电感耦合等离子体发射光谱法测定十五个稀土元素氧化物的配分量》的整合修订。本部分与ＧＢ／Ｔ１８８８２．２—２００２ 、ＧＢ／Ｔ１８８８２．３—２００２相比主要变化如下：
———电感耦合等离子体发射光谱法增加了４ 条参考谱线，分别为Ｌａ３７９．４７７ｎｍ、Ｃｅ４１３．３８０ｎｍ、Ｐｒ４２２．２９３ｎｍ、Ｓｍ４２８．０７８ｎｍ；
———对标准文本进行编辑性修改；
———增加了精密度（重复性）条款。
