本文件适用于Gd2O3粉末混合物和烧结球团中钆的测定？+？质量分数10的UO2和（（U，Gd）O2）？克/公斤到100？g/kg（即1？%至10？%），使用合适的ICP-AES仪器。 该方法能够证明符合商定的燃料质量标准和相关数据质量目标，前提是用户已在其已建立的测量控制程序下进行了鉴定测量，以证明测量不确定度要求将满足规范的期望置信度水平。

This document is applicable to the determination of gadolinium as Gd₂O₃ in powder blends and sintered pellets of Gd₂O₃？+？UO₂ and ((U, Gd) O₂) from mass fraction 10？g/kg to 100？g/kg (i.e. 1？% to 10？%), using a suitable ICP-AES instrument. This methodology is capable of demonstrating compliance with agreed upon fuel specifications and associated data quality objectives provided the user has performed qualification measurements under their established measurement control program to demonstrate that measurement uncertainty requirements will be met with the desired level of confidence at the specification.
