Condensed Saturated Humidity Mode:

The test temperature can be set between 105°F (40°C) and 158°F (70°C) – R.H. 95% ~ 100%.

Water Fog Mode – ASTM D1735 (Optional):
Test specimens are placed inside the test chamber following established technical standards or company-specific protocols. They are exposed to a fog generated with deionized water, and the test chamber is maintained at high humidity and elevated temperature.

Climatic Mode:
With programmable temperature vs. relative humidity ramps and plateaus, using sensors inside the test chamber (optionally with a temperature sensor on the specimen to ensure realistic temperature performance). Wet bulb and dry bulb sensors ensure accurate relative humidity (R.H.) control within the chamber.

Low Temperature or Ultra Low Temperature Mode:

• Low Temperature: -22°F (-30°C), with cooling and heating in the range of 176°F (80°C) down to -4°F (-20° C).
• Ultra Low Temperature: -40°F (-40°C), with linear cooling and heating from 176°F (80°C) down to -40°F (-40°F).

Caution Regarding Cross Chemical Contamination:
When the cyclic corrosion chamber r has previously been used for an acid test—AASS / CASS—or with any other solution (chemical product – corrosive agent) not specified by standards such as ASTM B117, NSS–ISO 9227, or NSS–JIS Z2371, or if it has been used for any purpose other than neutral salt spray testing, the chamber becomes chemically contaminated. The reverse scenario also results in contamination.

Therefore, the CCT CORR AUTO chamber must undergo a thorough cleaning procedure until the pH level complies with the guidelines established by technical standards. The corrosivity of the chamber must also be verified to ensure it does not significantly affect the results of subsequent tests.
It is essential to note that this cleaning process is challenging, and achieving full decontamination is nearly impossible.

Rack Material Requirements:
Racks must be constructed from non-metallic materials. If wood is used, it must be properly coated to prevent unwanted substances from interfering with the final test results.

Specimen Positioning:
Specimens should preferably be supported directly on the chamber floor. Plastic or slotted rubber profiles are suitable for supporting flat panels.
Suspension using glass hooks or waxed string is also acceptable, provided that the specimens maintain the specified positioning, which may require the use of secondary supports under the specimens.
