Claim 7:
8. The detection method as claimed in claim 1, wherein there is reiteration of the steps of determining a first variation of mass of inert gas between a first moment and a second moment, determining a first mass of inert gas in the insulation space at the first moment and second mass of inert gas in the insulation space at the second moment, calculating a second variation of mass of inert gas between the first moment and the second moment, and comparing the first variation of mass of inert gas with the second variation of mass of inert gas and triggering an alarm between a third moment, corresponding to the first moment incremented by a confirmation time, and fourth moment corresponding to the second moment incremented by the confirmation time, and wherein the presence of a leak is determined if said alarm is triggered again after the confirmation time has elapsed.
