Classification of the Corrosivity of the Atmosphere — Standardized Classification System and Approach for Adjustment

Source

Atmospheric corrosivity information is essential for selection of materials of construction, protective coatings and other measures used to prevent corrosion. Standards ISO 9223 - 9226 elaborated in ISO/TC 156/WG 4 are well accepted, used by corrosion engineers and introduced in other normative documents. Work on adjustment of the atmospheric corrosivity classification system is going on in the WG 4 with the aim to cover some gaps in this system. Statistical treatment of the ISOCORRAG program data and other data makes it possible to obtain a better definition of environmental influencies and specification of standard specimens. More sensitive procedures for corrosivity derivation for low aggressive indoor atmospheres have been recommended.
