Scope
This standard specifies the detection of hydrogen sulfide in liquefied petroleum gas. The detection sensitivity of this test standard is about 4mg/m3 of hydrogen sulfide (0.15~0.2grain/100ft3), which will cause the lead acetate test paper to turn yellow. If methyl mercaptan is present in liquefied petroleum gas, it will cause yellow stains on the lead acetate test paper, but it will completely fade within 5 minutes. In addition, if there are other types of sulfur in LPG
