1.1 This test method covers the determination of benzene and toluene in finished motor and aviation gasolines by gas chromatography.
1.2 Benzene can be determined between the levels of 0.1 and 5 volume % and toluene can be determined between the levels of 2 and 20 volume %.
1.3 The precision for this test method was determined using conventional gasoline as well as gasolines containing oxygenates (ethers such as methyl tert-butyl ether, ethyl tert-butylether and tert-amylmethylether).
1.4 It has been determined that this test method is not applicable to gasolines containing ethanol. Methanol may also cause interference.
