This test method determines the concentration of lead alkyl additives in gasoline. These additives improve the antiknock properties.

1.1 This test method determines total lead in gasolines containing lead alkyls at concentrations between 0.026 and 1.3 g Pb/L, and 0.12 and 6.0 g Pb/UK gal, 0.1 and 5.0 g Pb/US gal.

1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.2.1 The preferred units are grams per litre although both gram per US gallon and grams per UK gallon are acceptable due to their widespread use in the industry.

1.2.2 Temperature is given in degrees Fahrenheit and degrees Celsius in this test method.

1.3 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 hazard statements, see Sections 6 and 8.
