INTERNATIONAL STANDARD ISO 9223:2012(E) © ISO 2012 – All rights reserved 1 Corrosion of metals and alloys — Corrosivity of atmospheres — Classification, determination and estimation . 1. Scope . This International Standard establishes a classification system for the corrosivity of atmospheric environments. It

The C1 to C5 corrosion classification is based on BS EN ISO 12944-2 and BS EN ISO 9223 which is generally simplified as a table. This system is used across many manufacturing and construction industries to enable a common language of corrosion environments to which each industry can adapt their particular disciplines.

2023年6月12日 · This British Standard is the UK implementation of EN ISO 9223:2012. Together with BS EN ISO 9224:2011, BS EN ISO 9225:2011, and BS EN ISO 9226:2011, it supersedes BS EN 12500:2000, which is withdrawn. The UK participation in its preparation was entrusted to Technical Committee ISE/NFE/8, Corrosion of metals and alloys.

ISO 9223:2012 specifies the key factors in the atmospheric corrosion of metals and alloys. These are the temperature-humidity complex, pollution by sulfur dioxide and airborne salinity. The temperature-humidity complex can be evaluated in terms of time of wetness.
