The concentrations by volume or mass (weight) of the following components are generally reported:   Ethylene plus ethane  Propane  Propylene  Isobutane  n-Butane   Butene-1 plus isobutylene   trans-Butene-2   cis-Butene-2  Isopentane  3-Methylbutene-1  n-Pentane Pentene-1  2-Methylbutene-1  trans-Pentene-2  cis-Pentene-2   2-Methylbutene-2  This test method does not cover the determination of cyclic olefins, diolefins, or acetylenes. These are usually minor components in finished gasolines.  Samples to be analyzed should not contain significant amounts of material boiling lower than ethylene.  The values stated in SI units are to be regarded as the standard. Alternative units, in common usage, are also provided to improve the clarity and aid the user of this test method. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.【中国标准分类号】: E31【国际标准分类号】: 75_160_20【页数】: 【正文语种】: 英语
