ISO 8573-5:2025

ISO 8573-5:2001 specifies the gas chromatography test method for the determination of the content of oil vapors (hydrocarbons composed of six or more carbon atoms) in compressed air, regardless of the the origin of the compressed air, as well as the presence of any organic solvent in the steam, difficult to separate from other hydrocarbons. It also gives information on the procedure for using chemical indicator tubes during an initial assessment of the presence of oil vapors. ISO 8573-5:2001 provides considerations on sampling, measurement, evaluation, measurement uncertainties and presentation of the test report with respect to the parameter "oil vapor" of the class of compressed air purity, in accordance with ISO 8573-1. NOTE Lighter hydrocarbons composed of 5 carbons or less are treated as gaseous pollutants in ISO 8573-6.
