Utensil for stress corrosion tests characterized by being adapted to fracture tenacity specimens and mechanical test specimens, submerged horizontally in an aggressive environment and being coupled to a universal vertical testing machine. The tool solves the technical problem of carrying out stress corrosion tests with horizontal test specimens when only universal vertical test machines are available. The utensil is characterized by the following elements: - attach to the testing machine (1.1). - upper shaft (1.2). - two arms arranged in a similar way to those of a compass (1.3). - two lower axes (1.4). - two c-shaped bars (1.5). - four bearings (1.6). - two guides that contain lanes for the bearings (1.7). - threaded rods suitable for joining with the necessary pins in the fracture toughness tests in conditions of corrosion under tension (1.8).

Utensilio para ensayos de corrosión bajo tensión caracterizado por estar adaptado a probetas de tenacidad a fractura y probetas de ensayos mecánicos, sumergidas horizontalmente en un ambiente agresivo y por estar acoplado a una máquina universal de ensayos en disposición vertical. El utensilio resuelve el problema técnico de realizar ensayos de corrosión bajo tensión con probetas en disposición horizontal cuando sólo se dispone de máquinas universales de ensayos en disposición vertical. El utensilio se caracteriza por los siguientes elementos: - Acople a la máquina de ensayos. - Eje superior. - Dos brazos dispuestos de modo similar a los de un compás. - Dos ejes inferiores. - Dos barras en forma de C. - Cuatro rodamientos. - Dos guías que contienen carriles para los rodamientos. - Barras roscadas apropiadas para la unión con las clavijas necesarias en los ensayos de tenacidad a fractura en condiciones de corrosión bajo tensión.
