Abstract According to the VIM(3th),JJF 1001—2011and JJF 1059.1—2012, further comments have been made, and different views and proposed changes put forward as to several terms, definitions, notes in ISO/TR7066-1(1997), ISO5168(2005) and GB/T 29820.1—2013. Detailed analysis have been made on “random error”, “systematic error”, “standard deviation and variance”, “uncertainty and evaluation of measurement uncertainty”, “repeatability conditions”, “sensitivity”, and “calibration linear equation” in all above documents.
