为了确保尖头千分尺的校准数据的准确可靠,有必要将其纳入常规几何量的量值传递和溯源系统,根据尖头千分尺的工作原理和计量特性,文章提出其计量特性和校准结果不确定度评定,作为开展尖头千分尺校准的主要技术依据。
In order to ensure the accuracy and reliability of the calibration data of the micrometer, it is necessary to incorporate it into the conventional geometry of mass transfer and traceability system. According to the working principle and metrological characteristics of the micrometer, the article proposes its metrological characteristics and calibration results uncertainty Assessment, as the implementation of pointed micrometer calibration of the main technical basis.
