Abstract Corrosion Under Insulation (CUI ) of an insulated iron or other corrosion prone object (1) is detected by taking a sample (8) of the pore fluid from the pores of a permeable insulation layer (2) that covers at least part of the object (1) and analyzing the composition of the sample (8) on the presence of any tracer fluid, such as phospines, mercaptans, alcohols, acids, ketones and/or aldehydes emitted or acetic acid and/or butoxyethanol absorbed by any corrosion of the corrosion prone object (1) by a tracer fluid detection sensor (6). Selon l'invention, la corrosion sous isolation (CSI) d'un objet en fer isolé ou autre objet corrodable (1) est détectée par prélèvement d'un échantillon (8) du fluide interstitiel suintant des pores d'une couche d'isolation perméable (2) qui recouvre au moins en partie l'objet (1) et analyse de la composition de l'échantillon (8) en présence de tout fluide traceur, tel que phosphines, mercaptans, alcools, acides, cétones et/ou aldéhydes, généré ou d'acide acétique et/ou butoxyéthanol absorbé par toute corrosion de l'objet corrodable (1) par un capteur de détection de fluide traceur (6).
