Claim 3:
4. The method as claimed in claim 1, in which the thermal insulation barrier is a primary thermal insulation barrier, the tank (1) further including a secondary thermally insulation barrier (2) resting against a support structure and a secondary sealing membrane disposed between the secondary thermally insulation barrier (2) and the primary thermal insulation barrier, in which, for each test phase, there is measured a variable P2 representative of the pressure inside the secondary thermal insulation barrier (2), the variable P2 being measured during the step of cooling the internal space (11) of the tank (1) or during the step of loading the liquefied gas into the internal space (11) of the tank (I) and the variable P2 is compared to at least one secondary threshold and in which the fault is detected when the variable P2 crosses said at least one secondary threshold.
