测量方法的性能评价在计量学中是必不可少的。ISO 5725系列引入了重复性和再现性的概念，包括实验（通常是合作研究），以获得这些精度测量。ISO 5725系列主要描述了如何进行实验的管理部分，但对实验设计的统计方面只有很少的指导。在这样的实验中，这些精密度测量的准确性是重要的，实验者应该意识到这些精密度测量的偏差和精密度。这种实验的目的不限于简单地估计精度测量，而是以预期的精度获得这些测量。本文从统计学的角度提出了如何设计测量精度实验。本文首先研究了基于分布的精度测量的偏差和精度，然后提出了如何设计一个具有所需精度的实验。
Evaluating performance of a measurement method is essential in metrology. Concepts of repeatability and reproducibility are introduced in ISO 5725 series including experiments (usually collaborative studies) to obtain these precision measures. ISO 5725 series mainly describes managerial part on how to run an experiment, but there is only a little guidance on statistical aspects of the experimental design. In such an experiment, accuracy of these precision measures is important, and the experimenter should be aware of biases and precisions of these precision measures. The objective of such an experiment is not limited to simply estimate the precision measures but to obtain these measures with intended accuracy. This paper proposed how to design a measurement precision experiment from statistical point of view. This paper first investigated the bias and precision of the precision measures based on their distributions and then proposed how to design an experiment with the desired accuracy.
