Propylene for industrial use; Determination of hydrocarbon impurities; Gas chromatographic method
This International Standard specifies a gas chromatogrphic method for the determination of hydrocarbon impurities in ethylene for industrial use. The method is applicable to the determination of the impurities listed in annex B and principally to the determination of - mathane(CH4)at concentrations greater than 5ml/m3; - ethane (CH3-CH3)at concentrations greater than 5ml/m3; - acrtylene(ethyne)(CH≡CH)at concentrations greater than 1ml/m3; - proylene(CH3-CH2-CH3)at at concentrations greater than 2ml/m3; - propylene(propene)(CH2=CH-CH3)at concentrations greater than 2ml/m3.

Butadiene for industrial use; Determination of hydrocarbon impurities; gas chromatographic method
This international Standard specifides the manner of application of the Karl Fischer method for the determination of traces of water in light olefins from C2 to C4 for industrial use. The methos is applicable to products having water contents between 10 and 100mg/kg. For higher contents use ISO 760 as sampling is not valid when there is a risk that condensation of water may occur.
