BS ISO 12183:2016描述了纯硝酸钚电化学分析的分析方法 核级溶液，在置信水平下总不确定度不超过±0.2% 单次测定为0,95（覆盖系数K=2）。该方法适用于水溶液 钚含量超过0.5 g/L，试样中钚含量在4 mg至15 mg之间 钚。将该技术应用于含量小于0.5 g/L的溶液和试样 钚含量低于4 mg时，需要用户进行适用的实验证明 将达到数据质量目标。对于某些应用，需要在测量前通过阴离子交换对试样进行纯化，以 清除大量存在的干扰物质。参考第10条进行讨论 对干扰和纠正措施的评估。 纯化也适用于纯度较高的情况 测试样品的质量未知，或在制造过程中可能出现不可预测的波动。第11条讨论了可应用的方法和方法的应用变化，以及 选择测量参数时的重要注意事项，同时仍保持在 本文件的预期范围。交叉引用:ANSI N15。41:1984ANSI N15。51:1990ISO 17025JCGM 100:2008ISO/IEC 80000ISO 12803ISO 10980ISO 3696购买本文件时提供的所有当前修订版均包含在购买本文件中。

BS ISO 12183:2016 describes an analytical method for the electrochemical assay of pure plutonium nitrate solutions of nuclear grade, with a total uncertainty not exceeding ±0,2 % at the confidence level of 0,95 for a single determination (coverage factor, K = 2). The method is suitable for aqueous solutions containing more than 0,5 g/L plutonium and test samples containing between 4 mg and 15 mg of plutonium. Application of this technique to solutions containing less than 0,5 g/L and test samples containing less than 4 mg of plutonium requires experimental demonstration by the user that applicable data quality objectives will be met.For some applications, purification of test samples by anion exchange is required before measurement to remove interfering substances when present in significant amounts. Refer to Clause 10 for a discussion of interferences and corrective actions. Purification is also appropriate in situations where the purity of the test sample is unknown or when it may fluctuate unpredictably in a manufacturing process.Clause 11 discusses the changes in application of the method and methodology that can be applied and important considerations when selecting measurement parameters, while still remaining within the intended scope of this document.Cross References:ANSI N15.41:1984ANSI N15.51:1990ISO 17025JCGM 100:2008ISO/IEC 80000ISO 12803ISO 10980ISO 3696All current amendments available at time of purchase are included with the purchase of this document.
