ASTM D3348 Rapid Field Test for Trace Lead in Unleaded Gasoline
ASTM D3348 Standard Test Method for Rapid Field Test for Trace Lead in Unleaded Gasoline (Colorimetric Method)
1. Scope
1.1 This test method is intended for use in the field by nontechnical people for the quantitative measurement of lead in unleaded gasoline in the range from 0.01 to 0.10 g Pb/U.S. gal (2.64 to 26.4 mg Pb/L). This method applies to all commercial gasolines and responds to all types of lead alkyls as well as to other organic and inorganic forms of lead.

NOTE 1 - This test method is based on the use of the Mobil Lead Test Kit (Fig. 1).

NOTE 2 - This test method is a screening test and is not to be used as a replacement for Test Method D3116, Test Method D3229, or Test Method D3237.

1.2 The values stated in SI units shall be regarded as standard.

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 warning statements, see Section 7.
