The necessity of using sonic conductance C and critical pressure ratio b to describe the flow rate characteristics of pneumatic components was discussed firstly, then the principles and the test device of ISO/DIS6358 standard were introduced and its advantages and disadvantages were analyzed. An idea of substituting the ISO test measurement with the discharge method of isothermal chamber was consulted and the principles and test method were introduced. At last, a mathematic model of isothermal chamber is founded based on heat convection procedure in the chamber and is proved to be successful to predict the temperature variation characteristics of isothermal chambers with test results.
