The EQUILAM NA CORR AUTO model cyclic corrosion test chambers provide one of the most realistic simulations for accelerated corrosion testing. Some studies indicate that the test results closely resemble those obtained in outdoor exposure.

The C.C.T CORR AUTO corrosion chambers allow programming of cycles with time intervals (ramp or plateau) combined with the following modes:

• Salt Spray (Salt Fog)
• Stress or Spray (oscillating or fixed – optional)
• Immersion (optional)
• Warm saturated humidity condensed onto the samples (ISO 6270-2 – CH – ASTM D2247)
• Warm saturated humidity – water fog (ASTM D1735)
• Climatic Mode: Temperature vs. Relative Humidity with programmable ramps and plateaus. Range: 50°F to 176°F (10°C to 80°C) – R.H: 10% to 85% (Table 01)
• Low Temperature Mode: -22°F (-30°C), with heating and cooling and programmable ramps and plateaus.

Range: 176°F (80°C) to -4°F (-20°C)

• Ultra Low Temperature Mode: -40°F (-40°C), with linear heating and cooling and programmable ramps and plateaus.

Range: 176°F (80°C) to -40°F (-40°C)

Salt Spray (Salt Fog) Mode:

Test specimens are placed inside the test chamber following technical standards or company-specific protocols. They are subjected to controlled fog with corrosive agents (acidic, basic, or saline) in a high-humidity environment, using solutions defined by industry standards.

Spray (Stress) Mode – Oscillating or Fixed:

Optional mode, also available in a suspended oscillating configuration (mounted at the top).

The climatic mode features electric heating elements that enable rapid temperature ramping, meeting the needs of automotive cyclic corrosion tests with short transition times.

Immersion Mode:

The solution is pumped into the test chamber, immersing the test specimens. This solution can be heated or kept at ambient temperature.
