Abstract: In combination with the requirements of the explosion pressure test stipulated in the National Standard GB 3836.2- -2010 and the study on the large test results, the pressure occurred by the ignition of the explosion gas within the flameproof enclosure and the pressure variation process was analyzed.The test method of t he explosion pressure was introduced.The test gas density, the initial pressure, the gas replacement process and the test technical borehole selection and other factors affected to the explosion pressure test was analyzed and the related proposals were provided.Meanwhile the special noted items of the explosion pressure test for the s pecial equipment were stressed.
