: This field test measures vapor phase concentration at a specific moment and does not directly correlate to cap H sub 2 cap S levels in the liquid phase (refer to ASTM D7621 for liquid phase testing). ASTM International
Specifically calibrated for hydrogen sulfide ( H2Scap H sub 2 cap S astm d5705 pdf
Always perform the agitation, heating, and gas measurement steps inside a certified . Wear personal H2Scap H sub 2 cap S gas monitoring badges. : This field test measures vapor phase concentration
heating requirement is mandatory. Deviations in temperature radically alter how much gas desorbs from the oil, invalidating the test results. ASTM D5705 vs. Alternative Methods heating requirement is mandatory
in the vapor phase above residual fuel oils. Below is a report summary based on the D5705-20 Standard Test Report: ASTM D5705 1. Objective & Scope : To provide a rapid, consistent field method for measuring cap H sub 2 cap S
