SSH EN 12500:2006

Protection of metallic materials against corrosion - Corrosion likelihood in atmospheric environment - Classification, determination and estimation of corrosivity of atmospheric environments

Scope

This EN establishes a classification system for the corrosivity of atmospheric environments. It: - defines corrosivity categories of the atmospheric environments taking into account ISO 9223; - describes the determination of corrosivity based on assessment of mass loss of standard specimens after the first year of exposure; - can be used to estimate the corrosivity of an environment based on knowledge of local conditions or of specific data that characterize the local conditions, where it is not possible to make an experimental determination.
