Cyclic Corrosion Test Chambers (CCT)

Accelerated, Real-World Corrosion Simulation Through Controlled Cycles. Cyclic Corrosion Test Chamber (CCT) also know as Cyclic Salt Spray Test Chambers. While traditional salt spray testing provides baseline corrosion resistance data, real-world environments expose materials and assemblies to cyclic conditions, wetting, drying, humidity, temperature variation, and salt exposure.

Moving Beyond Static Salt Spray Testing

Innovation Rooted in Engineering Depth

CME Cyclic Salt Spray Chambers—also known as Cyclic Corrosion Test (CCT) Chambers—are engineered to replicate these complex, real-world corrosion mechanisms through precisely controlled environmental cycles.

Purpose-Built for Cyclic Corrosion Testing

CME CCT Chambers integrate salt spray, controlled humidity, drying, and temperature control within a single, unified testing platform.
Unlike basic salt spray systems, CME chambers are designed to execute programmable test sequences that more accurately represent field corrosion behavior.

Compliance with Global Cyclic Corrosion Standards

Precise Control of Corrosion Test Cycles

CME chambers provide precise control over each phase of the corrosion cycle—salt spray exposure, humidity dwell, dry-off, and temperature transitions.

Uniform spray distribution, stable humidity control, and repeatable temperature performance ensure consistent and comparable test results.

What is a Salt Spray Test Chamber?
A Salt Spray Test Chamber is a corrosion test system used to evaluate the resistance of materials, coatings, and surface treatments to corrosive salt-laden environments. It accelerates corrosion processes to assess product durability and coating performance.

What are Salt Spray Test Chambers also known as?
Salt Spray Test Chambers are also referred to as Salt Fog Chambers, Corrosion Test Chambers, or NSS (Neutral Salt Spray) Chambers, depending on the test method used.
