Corrosion of metals and alloys. Corrosivity of atmospheres. Classification, determination and estimation Ingestion-build-79769 ISO 140-2:19911 Scope This International Standard establishes a classification system for the corrosivity of atmospheric environments. It defines corrosivity categories for the atmospheric environments by the first year corrosion rate of standard specimens, gives dose response functions for normative estimation of the corrosivity category based on the calculated first year corrosion loss of standard metals, and makes possible an informative estimation of the
