Scope

1.1 This test method provides for the determination of the two (C_s) through five- (C₅) carbon paraffins and mono-olefins in gasolines. The concentrations by volume or mass (weight) of the following components are generally reported:

1.1.1 Ethylene plus ethane

1.1.2 Propane

1.1.3 Propylene

1.1.4 Isobutane

1.1.5 n-Butane

1.1.6 Butene-1 plus isobutylene

1.1.7 trans-Butene-2

1.1.8 cis-Butene-2

1.1.9 Isopentane 3-Methylbutene-1

1.1.10 n-Pentane

1.1.11 Pentene-1

1.1.12 2-Methylbutene-1

1.1.13 trans-Pentene-2

1.1.14 cis-Pentene-2

1.1.15 2-Methylbutene-2

1.2 This test method does not provide for the determination of cyclic olefins, diolefins, or acetylenes. These are usually minor components in finished gasolines.

1.3 Samples to be analyzed should not contain significant amounts of material boiling lower than ethylene.

1.4 SI (metric) units of measurement are preferred and used throughout this standard. Alternative units, in common usage, are also provided to improve the clarity and aid the user of this test method.

1.5 This standard does not purport to address all of the safety problems, 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.
