The combustible gas explosions occurred frequently in modern industry，and these hazards have resulted in a great amount of casualties and property losses. So the research of combustion and explosion of combustible gas in pipeline has become an important subject in the fields of safe technology. Flame arrester is a kind of safety equipment which can prevent flammable gas and liquid vapors from spreading，and widely used in petrochemical and natural gas industry in recently years.As a class of safety equipment

flame arrester is installed in the import and export of the device or pipe. Element which is the core components of flame arrester allows media circulation and block off the flame. With the development of modem society，people pay much attention on safe production. Accordingly，the performance test on flame arresters used for safe production seems to be necessary.The research of the flame arrester related detection technology started very later in China

and relative to the foreign standards

domestic standards technology is backward in technology

shorter period of refresh technology

incomplete standard system. So in this paper the study of flame arrester performance test method is carried out

in order to improve the detection level in this field

and promote the existing technology that complete performance detection of flame arrester. At the same time

it will be benefit for both of explosion prevention and the security of production and people.
