The solubility of gases changes drastically with temperature. A variance of even 2°C can skew the vapor concentration results.

ASTM D5705 is a critical international standard developed by ASTM International. It establishes the official procedure for measuring hydrogen sulfide ( H2Scap H sub 2 cap S ) in the vapor phase (headspace) above residual fuel oils.

Because ASTM international standards are protected by copyright laws, official documents cannot be legally downloaded for free from public forums or file-sharing websites.

For all practical applications, including regulatory compliance, it is strongly recommended to use the latest version, ASTM D5705-20.

Read the detector tube immediately after drawing the sample. The color boundary can fade or bleed if left sitting, leading to inaccurate readings. Conclusion astm d5705 pdf

Because ASTM standards are protected by international copyright laws, official, un-redacted files are not legally available for free download on public websites. Users requiring the complete, current version of the standard should purchase and download it directly from the official ASTM International website or authorized standards resellers.

: Staining of the tubes can sometimes lead to misinterpretation of results, making it less precise than laboratory methods like ASTM D7621 for liquid-phase analysis. Latest Revisions

While the core methodology remains consistent, the ASTM D5705-20 version includes important clarifications and updates: It establishes the official procedure for measuring hydrogen

ASTM D5705, officially titled "Standard Test Method for Measurement of Hydrogen Sulfide in the Vapor Phase Above Residual Fuel Oils," is a field test method for measuring H₂S in the equilibrium headspace (vapor phase) above a residual fuel oil sample. Developed by ASTM International (formerly the American Society for Testing and Materials), this standard provides a simple, consistent, and rapid method for assessing the H₂S concentration that may be present in storage tank headspaces.

Officially, no. The method is written for polyethylene. However, some labs adapt it for PP, but for true compliance, use ASTM E679 or contact ASTM.

Marine fuel specifications (such as ISO 8217 ) place strict limits on vapor-phase H2Scap H sub 2 cap S content to protect cargo integrity and vessel safety. Summary of the Test Method Procedure
