Safety attracts more and more attention with the modern chemical engineering industrial development. It is significant for chemical production safety to improve the intrinsic safety in the transport and storage of flammable gas and liquid

ensure the performance of explosion resistant performance of flame arresters and increase the using reliability. It is important to establish a perfect performance test and evaluation system. On the base of the previous relevant studies and standards

a new explosion resistant test system with different ignition methods was established. Two kinds of test were designed and the evaluation system was established quantitatively. The performance classifications of flame retardant

detonation retardant and explosion retardant were distinguished quantitatively by the pressure distribution obtained by the pressure sensors. Two kinds of tests on one flame arrester were conducted successfully and the results were consistent. The test system was proved to be feasible and reliable.
