Abstract: The analysis of the factors affecting the measurement uncertainty of the gloss meter mainly includes the uncertainty of the standard gloss plate, measurement repeatability, instrument stability, zero value error, and the standard uncertainty introduced by the resolution of the tested gloss meter . . Taking the first-class gloss meter as an example, the extended uncertainty of the measurement result of the display error is calculated according to the analysis based on the mathematical model, and at the same time, the report and expression form of the uncertainty of the measurement result are given.
Key words: gloss; indication error; uncertainty
