Specifies a procedure for the detection of hydrogen sulfide. The lower limit of detectability is 4 mg of hydrogen sulfide in 1 m^3 of gas. Methyl mercaptan, if present, produces a transistory yellow stain on the lead acetate paper which, however, fades completely in less than 5 min. Other sulfur compounds present in the gas do not interfere with the test.
Abstract
Overview
ISO 8819:1993 is an international standard developed by the International Organization for Standardization (ISO) that specifies a reliable method for detecting hydrogen sulfide (H2S) in liquefied petroleum gases (LPG). Known as the lead acetate method, this procedure provides a straightforward, sensitive test with a detection limit as low as 4 mg of hydrogen sulfide per cubic meter of gas. This standard plays a crucial role in ensuring safety and quality control in the handling and use of LPG by identifying the presence of this hazardous and corrosive gas impurity.
