EN ISO 9223 Corrosion of Metals and Alloys, Standard Test Method for Corrosion of Atmospheres

EUROLAB laboratory provides testing and compliance services within the scope of EN ISO 9223 standard. EN ISO 9223 establishes a classification system for the corrosiveness of atmospheric environments.

EN ISO 9223 Corrosion of Metals and Alloys, Standard Test Method for Corrosion of Atmospheres

It defines abrasiveness categories for atmospheric environments based on the first-year corrosion rate of standard samples, gives dose-response functions for the normative estimation of the abrasiveness category based on the calculated first-year corrosion losses of standard metals, and enables an informative estimation.

EN ISO 9223 of the corrosivity category based on local environmental information specifies the main factors in atmospheric corrosion of metals and alloys. These are the temperature-humidity complex, sulfur dioxide and pollution, and salinity in the air.

The temperature-humidity complex can be evaluated in terms of wetness time. The corrosion effects of other pollutants (ozone, nitrogen oxides, particles) are not considered decisive in the corrosivity assessment according to EN ISO 9223.

EN ISO 9223 does not characterize the corrosivity of certain service environments, such as atmospheres in the chemical or metallurgical industries.

EUROLAB assists manufacturers with EN ISO 9223 test compliance. Our test experts, with their professional working mission and principles, provide you, our manufacturers and suppliers, the best service and controlled testing process in our laboratories. Thanks to these services, businesses receive more effective, high-performance and quality testing services and provide safe, fast and uninterrupted service to their customers.
