As one of the most important parts for civil aircraft, the flame ability research for civil aircraft seats is very important, which can directly influence the flame ability of the civil aircraft passenger cabin. At present, the flame ability for civil aircraft seat are researched by follow tests: 1) the seat cushion oil burner test, which is carried to research the flame ability for seat cushion; 2) magnesium alloy seat structure oil burner test, which is carried to research the flame ability for magnesium alloy seat structure. Although they were different tests, there were still many similarities between them: 1) the research name and research scope of the seat cushion oil burner test and magnesium alloy seat structure oil burner test were highly similar; 2) they used the same burner during the test process. These similarities may cause the error during the test process and seriously affect the quality and safety of the aircraft. Thus, in this paper, the test method for seat cushion oil burner test and magnesium alloy seat structure oil burner test has been introduced, and the differences between two tests have been discussed.
