WebLead acetate test paper is generally regarded as selective for detection of hydrogen sulfide (ASTM 2006). Hydrogen sulfide reacts with lead ions from the lead acetate to form solid lead sulfide PbS, a black solid. H 2 S … WebA 2 parts-per-million (2 ppm) limit for H2S in bunkers took effect in July, 2012 under ISO-8217:2010. The IP-570 test method is the only test method allowed in ISO-8217 for determination of H2S in fuel oil. Testing for H2S content in residual fuel oils using IP-570 provides an enhanced ability to predict the potential release of dangerous H2S gas.
