ASTM D5705-20 is a standardized, field-applicable method for measuring hydrogen sulfide ( H2Scap H sub 2 cap S

Key Features and Benefits of ASTM D5705

Why is this test important?

Hydrogen sulfide is a highly toxic, flammable, and corrosive gas. In the petroleum industry, residual fuel oils (heavy fuels used in ships and power plants) can trap H₂S. During storage and transport, temperature changes or agitation can release this gas into the vapor space (headspace) of storage tanks. astm d5705 pdf

) in the vapor phase of residual fuel oils [5.1, 5.3]. It is critical for assessing safety hazards in storage tanks and marine vessels by measuring H2Scap H sub 2 cap S ASTM D5705-20 is a standardized, field-applicable method for

in the vapor phase above residual fuel oils. Often referred to as the "Can Test," ASTM D5705-20 is a standardized

Q2: What is the typical residual styrene limit?

A: ASTM D5705 does not set a pass/fail limit; it only defines the test method. However, quality specs often call for <0.5% residual styrene for low-emission resins or <1.5% for general purpose.

) in the vapor phase (headspace) above residual fuel oils. Often used as a rapid field test, it helps refiners and fuel terminals manage safety risks and quality control without requiring complex laboratory instrumentation like gas chromatographs. Key Features of ASTM D5705 : Field determination of cap H sub 2 cap S in the equilibrium headspace of fuel oil. Measurement Range : Applicable from (micromoles per mole). Applicable Materials
