| Abstract:In this study， the volume and its permissible deviation， calibration method， and calibration conditions of the vacuum vessel system in the relevant standards of smoothness tester were analyzed and the method of measurement uncertainty evaluation was used to verify that the calibration methods and conditions in the current standards were not compatible with the maximum permissible deviation of volume， and suggestions for revising the current standards were put forward as well. |
