GB/T 3392-2003 in English

《GB/T 3392-2003工业用丙烯中烃类杂质的测定 气相色谱法》由TC63（全国化学标准化技术委员会）归口，TC63SC4（全国化学标准化技术委员会石油化学分会）执行，主管部门为中国石油和化学工业联合会。
本标准规定了用气相色谱法测定工业用丙烯中浓度不小于0.0002％（体积分数）的甲烷、乙烷、乙烯、丙烷、环丙烷、异丁烷、正丁烷、丙二烯、乙炔、反-2-丁烯、1-丁烯、异丁烯、顺-2-丁烯、1,3－丁二烯、甲基乙烯等烃类杂质的方法。丙烯的纯度可由100.00%减去杂质的总量求得。

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.
