Server Corrosion
Metals, alloys, and metallic coatings are vulnerable to atmospheric corrosion, particularly under the influence of air humidity and environmental pollutants. Even a thin layer of corrosion on the surfaces of electronic systems, such as those in data centers, server rooms, and control rooms, can increase electrical resistance and compromise equipment performance. Therefore, continuous corrosion monitoring is essential to detect corrosion risks early, helping to optimize the performance of electrical systems.
Factors Affecting Atmospheric Corrosion
While threats like fire, power fluctuations, temperature, humidity, and airborne particulates are well-managed in server rooms, the corrosive potential of the air itself often goes unnoticed. Even trace levels of contaminant gases, at parts per billion (ppb), can corrode sensitive electronic components in servers.
Excessive corrosion can lead to warranty violations, circuit board failures, signal interference, and even total electronic component failure.
Why Monitoring Atmospheric Corrosion Rate and Reactivity is Crucial
Environments with higher levels of air contamination require heightened attention to air quality management. The combined effects of temperature fluctuations, humidity, and gaseous contaminants can significantly increase the corrosion risk, making it crucial to monitor the environmental conditions of IT infrastructure closely.
Any company reliant on sensitive IT infrastructure—such as data centers, server rooms, or control rooms—must establish a thorough monitoring system to evaluate the corrosion potential in their facilities.
The ISA-71.04.2013 standards classify environments based on their corrosion risk, which is assessed in terms of copper reactivity (in angstroms, Å).
| Class | Severity Level | Copper Reactivity | Comments |
|---|---|---|---|
| G1 | Mild | <300 Å | A well-controlled environment where corrosion is not a factor in equipment reliability. |
| G2 | Moderate | <1000 Å | A measurable corrosion effect, which may impact equipment reliability. |
| G3 | Harsh | <2000 Å | High likelihood of corrosion, requiring environmental controls or specially designed equipment. |
| Gx | Severe | ≥2000 Å | Only specially designed equipment is expected to survive in this environment. |
