ASTM D5705 is a standard test method developed by ASTM International. It is specifically designed to quantify the concentration of hydrogen sulfide (H₂S) in the vapor phase (headspace) of crude oil samples. As H₂S is a highly toxic and corrosive gas, accurate measurement is critical for refining, transportation safety, and regulatory compliance. While the full standard is available as a PDF purchase from ASTM, this informative text summarizes the scope, procedure, and significance of the method.

is a standard test method developed by ASTM International (formerly the American Society for Testing and Materials). Its primary purpose is to determine the concentration of hydrogen sulfide (H₂S) present in the vapor phase of residual fuel oils. astm d5705 pdf

The precision of this measurement depends on the "Henry’s Law" relationship, where the amount of dissolved gas in the liquid is proportional to its partial pressure in the gas phase above it. 5. Significance and Safety : H2Scap H sub 2 cap S ASTM D5705 is a standard test method developed
