This International Standard specifies a method for the detection of hydrogen sulfide in liquefied petroleum gases. The lower limit of detectability is 4 mg of hydrogen sulfide in 1 m3 of liquefied petroleum gas. Methyl mercaptan, if present, produces a transitory yellow stain on lead acetate paper which, however, fades completely in less than 5 min. Other sulfur com-pounds present in liquefied petroleum gas do not in-terfere with the test. NOTE 1 Liquefied petroleum gases and the products of their combustion should not be unduly corrosive or reactive to materials with which they come into contact. It is there-fore important that the presence of any hydrogen sulfide, a highly reactive substance, be detected. Additionally, the odour of hydrogen sulfide is unacceptable in some applica-tions of liquefied petroleum gases (e.g. lighter fuel).
