Test Systems that establishes the Corrosion Testing Equipment

Corrosion
Process System S (Salt Spray) - Basic System
ASTM B117, ASTM B368, ISO 9227, DIN 50021, JIS Z 2371

Using a two-component nozzle NaCl test solution is sprayed in the test chamber. Humidified compressed air - using demineralized water - sucks in the test solution from a constant level vessel. The fine salt fog is distributed evenly in the chamber. Parts of the system:

  • indirectly heated test chamber with electronical temperature control
  • one or more two-component nozzle(s)
  • supply tank for test solution
  • constant level vessel for test solution supply (alternative: dosing pump)
  • humidifier system with automatic water refill

Process System K (Condensed Water) - Basic System
ISO 6270-2 (CH and AT cycles), DIN 50017(KK and KTW cycles)

For the condensation water test demineralized water is filled in the bottom of the chamber. The bottom is heated indirectly, the water evaporates. Parts of the system:

  • indirectly heated test chamber with electronic temperature control
  • system for water refill.

Process System B (Ventilation) - Additional System
With system K: ISO 6270-2 (AHT Cycle), DIN 50017(KFW cycle),
With system S: VDA 621-415, VW PV1210, SWAAT ASTM G85 A3, GME 60213

The process system “ventilation” is used for ventilating, drying and cooling down of the test chamber and test samples. Ambient air passes through the chamber by a fan. The test room temperature decreases to ambient and the rel. humidity is reduced to ambient conditions. The ventilation system is added to the salt spray / condensation water system.

Process System W (Warm Air) - Additional System
With Systems S & B: ASTM G85 A5 Prohesion,
With Systems S & K & B: Nissan 1, Nissan 2, Honda 1, Mazda MCT-1H, Mazda MCT-2M, GME 9540 P

The warm air system is used for heating and fast drying of the test chamber and samples. It operates only in combination with process system “B” (ventilation). The difference to this system is that the ambient air is heated. The temperature can be controlled up to 60°C. You need this system for special combined tests such as Nissan CCT 1 or ASTM Prohesion.

Process System F (Humidity) - Additional System
With Systems S & K & B & W: ISO 11997-1, Nissan 4, Volvo 423-0014, Renault D17 2028 ECC1, Daimler PPAP 3002 (Filiform)

The process system “F” is used to control the rel. humidity in the test chamber. This system can only operate in combination with the systems ventilation (B) and warm air (W). You can control RH between 30% and 100% for temperature range between ambient and 50°C.

Process System C (Cooling) - Additional System
With Systems S & K & B & W & F: New VDA-CCT

In cycles that is needs a rapid change of the relative humidity in the chamber system C is used as a helper to System F. Also capable of reduction of the temperature down to -20°C which enables Low Temparature phase of new generation CCT tests.

Process System G (Gas) - Additional System
K,B Sistemleri ile birlikte: DIN 50018, ISO 3231

The gas process system is used for automatically dosing a defined volume of pollution gas (Sulphur dioxide). To start the test individual concentrations of gas volume are dosed into the test chamber. This system is available only for KBG 400 / 1000 A-SC.
