Abstract

This document defines a laboratory accelerated corrosion test method in two closely related variants. They are used in assessing the corrosion resistance of metals in environments where there is a significant influence of chloride ions, mainly as sodium chloride from e.g., winter road de-icing salt. The test variants contain humidity dynamics in proportions found in outdoor environments affected by corrosion and are balanced to receive realistic proportions of corrosion rates between various commonly occurring materials, coatings and engineering designs. The results obtained do not permit far-reaching conclusions on the corrosion resistance of the tested metallic material under the whole range of environmental conditions in which it may be used. Nevertheless, the method provides information on the relative corrosion resistance of a material exposed to a salt-contaminated environment with varying humidity conditions. The two accelerated laboratory corrosion test variants are applicable to: - metals and their alloys (ferrous and non-ferrous); - metallic coatings; - chemical conversion coatings; - organic coating on metals; - a combination of materials and coatings that include galvanic interactions and/or crevice conditions.
