The localised pressurised corrosion bench comprises a preparation reactor and a working reactor (2), of small size, each comprising a leaktight pressure-resistant metal chamber (101, 102), a set of electrical heating resistors (103) distributed on the perimeter of the said chambers, a beaker (104) made of an electrically insulating and temperature-resistant material, placed inside the chambers of each of the preparation and working (2) reactors, and means for applying a pressurised fluid inside each of the preparation and working (2) reactors. The working reactor (2) furthermore includes three series of sample holders (111 to 114; 115 to 118 and 119 to 122) for the individual support of each of the working electrodes, the three series of sample holders (111 to 114; 115 to 118 and 119 to 122) being arranged vertically and offset from each other by approximately 90 DEG . The back electrode has a surface area at least of the order of a hundred times the area of an individual sample constituting a working electrode. <IMAGE>
