Environmental corrosion Very low Low Average High Very high Extreme
Examples of environments Indoors Heated areas with arid atmosphere and insignificant quantities of pollutant, e.g. offices, shops, schools and hotels. Non-heated areas with fluctuating levels of temperature and humidity. Few instances of condensation and low levels of airborne pollution, e.g. sports halls and warehouses. Average levels of humidity and some airborne pollution resulting from production processes, e.g. breweries, dairies, laundries. High humidity and considerable airborne pollution as the result of production processes, e.g. chemical plants, swimming pools and dockyards. Buildings with almost permanent condensation and with high pollution Industrial buildings with extreme humidity and aggressive atmosphere.
Outdoors   Atmospheres with low levels of airborne pollution. Rural areas. Atmospheres containing some salt or average levels of air-borne pollution. Urban and light industrial areas. Areas affected by coastal conditions. Atmospheres with average salt content or discernible levels of airborne pollution. Industrial and coastal areas. Industrial areas with high humidity and aggressive atmosphere, and coastal areas with high salinity Offshore areas with high salinity, industrial areas with extreme humidity, and aggressive atmospheres, sub-tropical or tropical atmospheres.
