Scope

1.1 This test method covers the determination of benzene, toluene, and total aromatics in finished motor gasoline, including reformulated gasoline (RFG) containing oxygenated blending components, by gas chromatography/mass spectrometry (GC/MS).

1.2 This test method is applicable to the following concentration ranges, in liquid volume %, for the following aromatics: benzene, 0.1 to 3%; toluene, 1 to 15%; and total (C6-C12) aromatics, 10 to 40%. The test method has not been tested by ASTM for gasoline samples containing a concentration of uncalibrated C10-C12 aromatic compounds greater than approximately 3 volume %. Also, the test method has not been tested by ASTM for individual hydrocarbon process streams in a refinery, such as reformates, fluid catalytic cracked naphthas, etc., used in blending of gasolines.

1.3 Results are reported to the nearest 0.01% for benzene and 0.1% for the other aromatics by either mass or liquid volume.

1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.5 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.
