Paints and varnishes — Corrosion protection of steel structures by protective paints systems — Part 2: Classification of environments


This document deals with the classification of the principal environments to which steel structures are
exposed, and the corrosivity of these environments. This document
— defines atmospheric-corrosivity categories, based on mass loss (or thickness loss) by standard
specimens, and describes typical natural atmospheric environments to which steel structures are
exposed, giving advice on the estimation of the corrosivity,
— describes different categories of environment for structures immersed in water or buried in soil, and
— gives information on some special corrosion stresses that can cause a significant increase in
corrosion rate or place higher demands on the performance of the protective paint system.
The corrosion stresses associated with a particular environment or corrosivity category represent one
essential parameter governing the selection of protective paint systems.
