Méthode à deux électrodes utilisant l'acide acétique pour mesurer le potentiel de piqûre de l'aluminium et des alliages d'aluminium dans des solutions de chlorure

This document specifies a test method for the measurement of the pitting potential of aluminium and aluminium alloys in sodium chloride solution of a mass fraction of 5 %, with a fixed concentration of acetic acid as the oxidant, using a two-electrode system. This document provides a simple method for ranking aluminium alloys and is especially useful for evaluating galvanic protection performance of thin clad materials because the test method causes little specimen damage.
