Standard Test Method for Measurement of Hydrogen Sulfide in the Vapor Phase Above Residual Fuel Oils
 N D5705

Annotation

This test method covers the field determination of hydrogen sulfide (H2S) in the vapor phase (equilibrium headspace) of a residual fuel oil sample.

The test method is applicable to liquids with a viscosity range of 5.5 mm2/s at 40°C to 50 mm2 /s at 100°C. The test method is applicable to fuels conforming to Specification D396 Grade Nos. 4, 5 (Heavy), and 6.

The applicable range is from 5 ?mol ?mol to 4000 ?mol ?mol (micromoles per mole) (5 ppm v ?v to 4000 ppm v/v (parts per million by volume)).

The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.

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.
