Corrosion of metals and alloys. Corrosion fatigue testing. Part 2 :crack propagation testing using precracked specimens.

La présente partie de l'ISO 11782 décrit une méthode reposant sur la mécanique de la rupture, permettant de déterminer les vitesses de propagation de fissures préexistantes sous chargement cyclique en milieu contrôlé et de mesurer la plage de facteur d'intensité de contrainte limite pour la propagation de fissure au-dessous de laquelle la vitesse de progression de la fissure devient inférieure à une limite définie convenue entre les parties. La présente partie de l'ISO 11782 donne des indications et des instructions sur les essais de fatigue-corrosion des métaux et des alliages en milieux aqueux ou gazeux.
