- Scope
- 1.1 This standard specifies the determination of methane, ethane, ethylene, propane, cyclopropane, isobutane, n-butane, propadiene, acetylene, and trans-butane with a volume fraction of not less than 0.0002% in industrial propylene by gas chromatography. 2-butene, 1-butene, isobutene, cis-2-butene, 1,3-butadiene, methyl acetylene and other hydrocarbon impurities. The volume fraction of propylene can be obtained by subtracting the total amount of impurities from l00.O0%. Since this standard cannot measure all possible impurities, such as hydrogen, oxygen, carbon monoxide, carbon dioxide, water, oligomers, and alcohol compounds, other test methods are required to fully characterize propylene samples. 1.2 This standard is not intended to address all safety issues associated with its use. Therefore, users of this standard should establish appropriate safety and protection measures in advance and determine appropriate management systems.
