| The IT Exacta has been validated to achieve accurate diffusion flowrate, HydroCorr flowrate and bubblepoint test results for a full range of filters. The pressure decay based test procedures rely on the accurate determination of the pressure decay from a defined test pressure to determine the gas flowrate that is compared to the filter specification. There are two sources of error that could contribute to the accuracy and reliability of the filter test result. These are the accurate determination of the pressure decay rate and the determination of the gas volume within which the pressure decay occurs (to within 5%).
