The measurement uncertainty assessment of the test and calibration results is widely used in measurement comparison,measurement calibration and the new construction and review of measurement standards,etc.A good measurement uncertainty assessment of the test results is an important guarantee for the laboratory to improve the reliability of the test results issued,is a reflection of the laboratory testing capabilities,is also an indispensable part of measurement testing.This paper introduces the process of the measurement uncertainty assessment of 0.4 level precision pressure gauge calibration results,providing reference for the reader's future application.
