Paper Abstract

Flow-rate characteristics of pneumatic component are represented by sonic conductance C and critical pressure ratio b as specified by ISO 6538. In this method, Components are considered having ellipse flow-rate characteristics. However, since there are many of pneumatic components that ISO 6358 method can't represent proximately, regardless of whether or not calculated component is independent or composed, the flow-rate characteristics curve is not always like an ellipse, and the accuracy of sequential composition itself is questioned to air flow which passes though multiple components simultaneously. For this reason, the modification of composition method is present which ISO/WD 6358-2 is. In the paper, Error comparison between ISO/WD 6358-2 and ISO 6358:1989 have been done, the results show that error are small between them, but ISO/WD 6358-2 extends the applicable range of standard.
