带表千分尺示值误差测量结果不确定度评定

摘要

According to verification regulation of micrometers with gauge JJG 427-2004, the article combines the actual test work, and analyses each error component’s composition of the micrometers with gauge is detected by grade 4 gauge block; evaluation of uncertainty about Indication Error for the Micrometers with gauge in Measurement is introduced. The article provides scientific support for the verification work.%根据JJG 427-2004带表千分尺检定规程，结合检定工作实际，分析了用4等量块检定带表千分尺过程中各误差分量的构成，介绍了其示值误差测量结果不确定度的评定方法，为检定工作提供科学保障。
