    Abstract - (Show below) - (Hide below)

    La présente Norme internationale spécifie l'appareillage, les réactifs et le mode opératoire à utiliser lors des essais au brouillard salin neutre (NSS), au brouillard salin acétique (AASS) et au brouillard salin cupro-acétique (CASS) permettant d'évaluer la résistance à la corrosion de matériaux métalliques, avec ou sans revêtement temporaire ou permanent de protection contre la corrosion. Elle décrit également la méthode à appliquer pour évaluer la corrosivité du milieu de la chambre d'essai. Elle ne spécifie pas les dimensions des éprouvettes, la durée d'exposition à appliquer pour un produit particulier ou l'interprétation des résultats. Ces détails sont fournis dans les spécifications de produit correspondantes. Les essais au brouillard salin sont particulièrement utiles pour détecter les discontinuités du type pores ou d'autres défauts de certains revêtements métalliques, organiques, d'oxyde anodique ou de couches de conversion. Les méthodes au brouillard salin conviennent toutes pour vérifier que la qualité comparative d'un matériau métallique, avec ou sans revêtement protecteur contre la corrosion, est maintenue. Il n'est pas recommandé de les utiliser pour des essais comparatifs en vue de classer les différents matériaux les uns par rapport aux autres vis-à-vis de la résistance à la corrosion.
