Beschreibung
Zusammenfassung:	The invention relates to a method for checking the leakproofness of a leakproof tank for storing a liquefied gas at low temperature, the tank comprising an internal shell (2) and a secondary sealing membrane (7), a secondary space (6) arranged between the internal shell (2) and the secondary sealing membrane (7), a primary sealing membrane (9) and a primary space arranged between the primary sealing membrane (9) and the secondary sealing membrane (7). The method comprises the following main steps: - generating, in the secondary space (6), a pressure lower than the pressure of the primary space (8) by means of an aspiration device (80), - measuring the temperature of an external surface of the internal shell (2), - detecting the location of a leak in the secondary sealing membrane (7) in the form of a cold spot on the outer surface of the internal shell (2). 本发明涉及一种用于检查用于储存低温的液化气体的防漏贮罐的防漏性的方法，所述贮罐包括内壳(2)和次级密封膜(7)、布置在所述内壳(2)和所述次级密封膜(7)之间的次级空间(6)、初级密封膜(9)以及布置在所述初级密封膜(9)和所述次级密封膜(7)之间的初级空间。所述方法包括以下主要步骤：借助于抽吸装置(80)
