|Filters for compressed air— Test methods—Part 3: Particulates
First edition (2009)
|ISO 12500-3 specifies test and inlet (challenge) conditions for compressed air filters for particle separation. ISO 12500-3 determines the (fractional) efficiency and the according differential pressure of a compressed air filter at the standardized test and inlet conditions:
|ISO 12500-3 allows to determine the efficiency of a compressed air filter either at pressure or at atmospheric conditions while efficiency depends on the working pressure. Thus for comparison it is important to pay attention if the test was carried out at 7 bar or 0 bar working pressure, respectively.
