标准范围

本文件规定了电化学测量核级纯硝酸钚溶液的分析方法，扩展不确定度不超过±0.2？单次测定的置信水平为0.95的%（覆盖因子，k？=？2）。该方法适用于含钚大于0.5？g/l和含钚的测试样品在4？mg和15？毫克。该技术在含钚小于0.5的溶液中的应用？g/l和含钚小于4？mg要求用户通过实验证明将满足适用的数据质量目标。

This document specifies an analytical method for the electrochemical measurement of pure plutonium nitrate solutions of nuclear grade, with an expanded uncertainty not exceeding ±0,2 % at the confidence level of 0,95 for a single determination (coverage factor, k = 2). The method is applicable for aqueous solutions containing plutonium at more than 0,5 g/l and test samples containing plutonium between 4 mg and 15 mg. Application of this technique to solutions containing plutonium at less than 0,5 g/l and test samples containing plutonium at less than 4 mg requires experimental demonstration by the user that applicable data quality objectives will be met.
