Currently,there is a lack of calibration specifications and corresponding calibration devices for the stan-dard zero scale snap gauge for testing the rocket skid track.To ensure the accuracy and reliability of the value of the quantity of the standard zero scale snap gauge for testing the rocket skid track,the dedicated calibration device for the standard zero scale snap gauge for testing rocket skid track is developed.Based on the structural characteristics of the standard zero scale snap gauge,the main technical indicators of the dedicated calibration device for the standard zero scale snap gauge are proposed,the dedicated calibration device for the standard zero scale snap gauge is designed,and the measurement uncertainty of the calibration result is evaluated.The evaluation results show that the extended measurement uncertainty of measurement result of the dedicated calibration device for the standard zero scale snap gauge is 0.006 mm,which is less than the target measurement uncertainty of 0.01 mm,and has the ability to trace the value of the quantinty of the standard zero scale snap gauge for testing the rocket skid track.
