Abstract: The pressure leak calibration apparatus is a kind of a metrology standard for gas leak rate.The pressure leak can be calibrated with the constant volume method and the dynamic comparison method of quantitative gas.The calibration range is from 10 2 to 5×10 -5 Pa·L/s .The calibration principle,the design method and the parameters selection for the pressure leak calibration apparatus are introduced.
