ASTM D4420-94(1999)e1 PDF

Scope: 1.1 This test method provides for the determination of benzene, toluene, C8, C9 and heavier aromatics, and total aromatics in finished motor gasoline. It is also applicable to gasoline blending components. NOTE 1—For analysis of gasolines for benzene and toluene, solely, Test Method D 3606 can be used. 1.2 This test method is applicable to the following concentration ranges, in liquid volume percent, for the individual aromatics listed above: benzene, 0.1 to 5; toluene, 1 to 20; C8, 3 to 25; C9 and heavier, 5 to 30, and total aromatics, 10 to 80. 1.3 It has not been determined whether this test method is applicable to gasoline containing oxygenates; for example, ethers and alcohols. 1.4 Results are reported to the nearest 0.1 % by liquid volume. 1.5 The values stated in SI units are to be regarded as the standard. 1.6 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. For specific precautionary statements see Sections 6.1 through 6.8 and 7.1.
