The American National Standards Institute offers the standard (including past versions like D5705-15) for purchase.
The test method applies to a range from 5 μmol/mol to 4000 μmol/mol (5 ppm v/v to 4000 ppm v/v).

concentrations in the equilibrium headspace of a sample, which is essential for ensuring both and product quality control in refineries and fuel terminals. Scope and Application astm d5705 pdf
Hydrogen sulfide is a highly toxic, colorless, and flammable gas. At low concentrations, it smells like rotten eggs, but at higher concentrations, it quickly paralyzes the sense of smell.
This article serves as an overview of the standard, its applications, and how to acquire the . What is ASTM D5705?
into the tank headspace is accelerated, creating lethal pockets of gas for survey personnel and ship crews. 2. Operational Safety and Explosive Risks H2Scap H sub 2 cap S concentrations in the equilibrium headspace of a sample,
at levels above 100 ppm is immediately dangerous to life and health (IDLH). This test ensures that terminal workers and ship crews know the risks before opening tank hatches or entering confined spaces. H2Scap H sub 2 cap S

A calibrated bellows or piston-style hand pump designed to draw a precise volume of headspace gas through the detector tube. Step-by-Step Testing Procedure
: Applicable to residual fuel oils (Grade Nos. 4, 5, and 6) with a viscosity range of 40 raised to the composed with power C 100 raised to the composed with power C Measurement Range : Typically covers cap H sub 2 cap S concentrations from 5 to 4000 ppm v/v (parts per million by volume). Testing Principle
escapes rapidly when exposed to air. Never leave sample containers uncapped, and minimize fuel agitation during the initial pouring phase.
