Corrosion of metals and alloys - Corrosion in artificial atmosphere - Accelerated corrosion test involving exposure under controlled conditions of humidity cycling and intermittent spraying of a salt solution (ISO/DIS 16701:2023); German and English version prEN ISO 16701:2023
Abstract
This document specifies an atmospheric accelerated test procedere in two closely related variants, A and B, containing intermittent salt exposure combined with dynamic humidity patterns, variant A at constant dew point, variant B at constant temperature. 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 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. This document also specifies requirements on the test equipment and contains detailed procedures for quality control, including recommended instrumentation. This document does not specify the dimensions of the tests specimens, the exposure period to be used for a particular product, or the interpretation of the results. Such details are provided in the appropriate product specifications.
