This International Standard establishes a classification system for the corrosivity of atmospheric environments.
It
- defines corrosivity categories for the atmospheric environments by the first-year corrosion rate of
standard specimens,
- gives dose-response functions for normative estimation of the corrosivity category based on the
calculated first-year corrosion loss of standard metals, and
? makes possible an informative estimation of the corrosivity category based on knowledge of the local
environmental situation.
This International Standard 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.
Temperature is also considered an important factor for corrosion in areas outside the temperate macroclimatic
zone. The temperature-humidity complex can be evaluated in terms of time of wetness. Corrosion effects of
other pollutants (ozone, nitrogen oxides, particulates) can influence the corrosivity and the evaluated one-year
corrosion loss, but these factors are not considered decisive in the assessment of corrosivity according to this
International Standard.
This International Standard does not characterize the corrosivity of specific service atmospheres,
e.g. atmospheres in chemical or metallurgical industries.
The classified corrosivity categories and introduced pollution levels can be directly used for technical and
economical analyses of corrosion damage and for a rational choice of corrosion protection measures. |
