Scope

This standard specifies the chemical grade propylene purity and methane, ethane, ethylene, propane, cyclopropane, isobutane, n-butane, propadiene, acetylene, trans-2-butylene, 1-butene, isobutylene, cis -Gas chromatography method for the determination of hydrocarbon impurities such as 2-butene, 1, 3-butadiene, and methyl acetylene. This standard is applicable to the determination of propylene samples with a purity of not less than 90% (volume fraction) and an impurity content of not less than 0.001% (volume fraction). Since this standard cannot measure all possible impurities, such as hydrogen, oxygen, carbon monoxide, carbon dioxide, water, oligomers, sulfur and oxygen-containing compounds, other test methods need to be applied to fully characterize propylene samples.
