Scope

This part of GB/T 19292 establishes a classification system for the corrosiveness of the atmospheric environment.
This section defines the corrosive classification of the atmospheric environment according to the corrosion rate of the first year of the standard sample;
Annual corrosion weight loss gives a dose-response function for the normative assessment of corrosivity levels; corrosive based on local environmental conditions
Level data assessment is possible.
This section specifies the key factors for atmospheric corrosion of metals and alloys, including the combined effects of temperature and humidity, sulfur dioxide pollution and air.
Salt pollution.
Temperature is also considered to be an important factor in the corrosion of temperate climate zones. The combined effect of temperature and humidity can be assessed based on the wet time.
Corrosion of other contaminants (including ozone, nitrides, particulate matter) can affect corrosivity and estimated annual corrosion weight loss, but these factors
Not a decisive factor in the assessment of corrosion based on this section.
This section does not apply to atmospheric corrosiveness in special environments, such as chemical or metallurgical industrial atmospheres.
Corrosion grades and pollution levels can be directly used for technical and economic analysis of corrosion damage, as well as for the rational selection of corrosion protection measures.

Summary	This standard specifies the key factors for the atmospheric corrosion of metals and alloys, including the combined effects of temperature and humidity, sulfur dioxide pollution and salt pollution in the air. Temperature is also considered to be an important factor in the corrosion of temperate climate zones. The combined effects of temperature and humidity can be evaluated based on the wet time.
