PURPOSE: A door sealing test method is provided to carry out a sealing test by mounting a door or window on the front side of an airtight space and pressurizing air in the airtight space. CONSTITUTION: A door sealing test method comprises the steps of: mounting a door sealing test device(100) on a main body(110), actuating a plurality of pneumatic cylinders(150) so that a fixing lever(154) presses a window and door(D) against a border frame(120a) of an airtightness space(120), using a high pressure fan to pressurize to 10~500Pa, checking a differential pressure display and a flow rate display, and obtaining a measurement result of the sealing test.
