ASTM D6021-96(2001)e1 - 1.1.2001
 
1. Scope

1.1 This test method covers a method suitable for measuring the total amount of hydrogen sulfide (H2S) in heavy distillates, heavy distillate/residual fuel blends, or residual fuels as defined in Specification D396 Grade 4, 5 (Light), 5 (Heavy), and 6, when the H2S concentration in the fuel is in the 0.01 to 100 g/g (ppmw) range.

1.2 The values stated in SI units are to be regarded as the 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 hazard statements, see 5.1, 7.5, 8.2, 9.2, 10.1.4, and 11.1.
