Abstract
It is an object of the present invention to provide same results of leak judgments even if conditions such as temperature and pressure vary as long as sizes of sealing defects are same. A leak device 5 that generates regular leakage under regular temperature and pressure is made communicable with a test path 19 through which a test pressure is provided. A device actual measurement leak value of the leak device 5 is actually measured by a leakage measuring instrument 33. An object actual measurement leak value of a test object 9 is actually measured by the leakage measuring instrument 33. The object actual measurement leak value is converted into a regular-conditions-converted leak value based on the device actual measurement leak value and a leakage is judged based on the regular-conditions-converted leak value.
