ASTM D3237 – Standard Test Method for Lead in Gasoline by Atomic Absorption Spectroscopy
Description:
Significance and Use
5.1 This test method is used to ensure compliance of trace lead as required by federal regulation for lead-free gasoline (40 CFR part 80).
Scope
1.1 This test method covers the determination of the total lead content of gasoline within the concentration range of 0.010 g to 0.10 g of lead/U.S. gal (2.5 mg/L to 25 mg/L). This test method compensates for variations in gasoline composition and is independent of lead alkyl type.
1.2 The values given in grams per U.S. gallon are to be regarded as the standard in the United States. Note that in other countries, other units can be preferred.
