for corrosivity categories
Annex B (informative) - Average initial corrosion
rates and average steady corrosion rates in
intervals relative to classified corrosivity
categories

of steels with regard to steel composition
Bibliography
Describes guiding values of corrosion attack for metals and alloys exposed to natural outdoor atmospheres for exposures greater than one year.
| DevelopmentNote |
Together with UNI EN ISO 9223, UNI EN ISO 9225 and UNI EN ISO 9226, it supersedes UNI EN 12500. (03/2012)
