RS ISO 8819: 1993
Liquefied petroleum gases — Detection of hydrogen sulphide — Lead acetate method
Abstract

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 compounds
present in liquefied petroleum gas do not interfere
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 therefore
important that the presence of any hydrogen sulfide, a
highly reactive substance, be detected. Additionally, the
odour of hydrogen sulfide is unacceptable in some applications
of liquefied petroleum gases (e.g. lighter fuel).
