Overview of Atmosphere-Compass: the Software Tool for Atmospheric Corrosion Prediction and Modeling

Atmosphere-Compass is the only device and OS independent software tool on the market for the service life prediction and modeling of atmospheric corrosion of metals and alloys in compliance with ISO 9223 and ISO 9224. Designers, architects, OEM engineers, consultants, operation personnel, maintenance and inspection engineers can quickly determine the expected service life of a structure or component exposed to indoor or outdoor atmospheres, anytime, anywhere, on any device running any OS without the need to install or download anything. Atmosphere-Compass also predicts the corrosion rate, the maximum and average corrosion depth, the rust rating number and rust area ratio of equipment or structures based on the following inputs:

• material type/grade

• age of structure

• nominal thickness

• exposure condition - indoor or outdoor

• exposure environment

• site specific data if available (temperature, relative humidity, sulfur dioxide (SO₂) and chloride deposition rates)

The outputs of Atmosphere-Compass include the following:

• the atmosphere corrosivity category

• the atmosphere corrosivity ranking

• the degree of rust and stains on the surface measured by the rust rating number (RN) and the rust area ratio (%) as per BS ISO 23721 standard.

• the maximum or average corrosion depth at the specified age of the equipment or structure

• the corrosion rate at the specified age of the equipment or structure

• the remaining life of the equipment or structure

• a plot of the corrosion depth (µm) vs. service life in years

Figures below show the screen shots of Atmosphere-Compass.
