介绍了重复性在计量标准中的重要作用,针对只提供稳定的、满足一定不确定度要求的量值(单值或多值)计量标准装置,对其重复性的试验方法进行了讨论,并以“覆膜电极溶解氧测定仪”为例,对其测量数据进行计算分析,对于此类计量标准装置的重复性进行考核时,应考虑实际情况,选择最确切反映计量标准重复性的试验方法。
The importance of repeatability in metrological standards is introduced. The repeatability test method is discussed in terms of measuring standard devices that provide only a stable quantity (single or multiple) that meets certain uncertainties. Take “coated electrode dissolved oxygen analyzer” as an example, its measurement data are calculated and analyzed. When evaluating the repeatability of such measurement standard devices, the actual situation should be considered, the most accurate choice of measurement standard repeatability experiment method.
