Corrosionbox improves comparison with outdoor results

Worldwide, materials used by manufacturing industry are exposed to natural or industrial
corrosion in shape of salt fog, humidity, smoke and vehicle exhaust. Laboratory
corrosion tests are used extensively for selection of materials and their surface
protection.

Corrosionbox chambers are what you need to predict corrosion resistance of materials
such as paints and coatings.
 
Salt spray test

A corrosive solution is turned into a vapour mist through a nozzle located on the back side of the chamber. A fog diffusing structure distributes the fog over the entire test zone. The compressed air required for fog production is heated and saturated with moisture in a pressurized humidifier before it reaches the nozzle. One or more heating elements, depending on chamber capacity, ensure uniform temperature in the test chamber. Exhaust solution collected in the bottom of test chamber is drained away through a drain to the floor.

Salt spray test can be executed with all chamber models.
 
Condensation water test

Test chamber bottom is filled with demineralised water. Water is heated and evaporates condensing on the surface of samples. Chamber temperature is 40 °C. Continuous condensation test can be executed with all chamber models.

Cyclic corrosion test

A large number of cyclic corrosion tests are made possible by combining salt spray environment with condensation humidity and air drying . Cyclic corrosion testing has become increasingly necessary in recent years. Dry Corrosion is one of the most popular cyclic tests alternating salt spray and air drying. Cyclic tests can be executed with all enhanced model chambers. Depending on cycletype some options have to be installed during chamber manufacturing.

 
Chamber Design

Chamber structure is overall 10mm thick Polypropylene. Option in PPS plastics to meet CSA flame test. Test chamber is insulated with a double wall. Access to the test chamber is
made through a window glass door. Control panel and all necessary control devices are on the right
side in ergonomic position. The Salt solution storage tank is on the left side. The electrical board is completely enclosed in a dedicated zone: next to it we find the electro-valves, humidifier and salt solution dosing pump zone. Each part is of easy access for simple and fast maintenance.
 
Basic model
 
Absolutely easy to use. The first step for test execution is to load timer with total test time (up to 9999 hours), second is to set test chamber temperature on the controller, then press Salt spray or Condensation push-button. During the whole time of the test, the timer counts down and its display will indicate decreasing time running to test end. To inspect samples, suspend test execution pressing Salt spray or Condensation push-button, then press ventilation push-button to drain test
chamber before opening it.
To resume test execution simply press Salt spray or Condensation push-button
again. When timer reaches zero test execution is finished
 
Enhanced model
Free programming, up to 15 different test programs, inputs via keyboard with soft keys and easy to use structure of the Menu. Test status is continuously displayed on the large LCD display with 4 lines of 20 characters each. Control and monitoring of test chamber and humidifier temperature, monitoring of nozzle air pressure and dosing pump RPH. Self-diagnostic including warning messages, alarm messages and safety shut down. Complete test report: chamber and humidifier temperature, nozzle air pressure and dosing pump RPH are periodically measured and stored in
the controller memory together with test interruptions or alarms. By simply pressing a key a complete report of the test is printed. RS232-C interface is provided for serial printer connection.
 
Cyclic test options

Enhanced model control panel allows easy programming of cyclic test combining: Salt spray, Water
condensation, Dry off and Ambient condition. To perform cycling the test chamber must be completed with the following optional parts:
 
Option for Dry Corrosion, Scab Corrosion cycle. An air heater is installed to heat purging air before introducing it in the test chamber and a Titanium panel on the bottom of test chamber turns a flooded bottom into a dry bottom. Only a dry chamber bottom allows fast drying of the samples.

Option for ASTM G85-98 annex 5 Prohesion. In addition to parts installed for dry corrosion a bypass is installed on the humidifier to meet standard requirements with respect to fog production.

Option for ASTM G85-98 annex 4 salt/SO2 spray testing. An external SO2 dosing system is supplied and a gas diffusing device is installed in the test chamber
National and international Standards

In order to generate reliable and comparable results, a large number of test methods and international standards have been developed and are relied upon as reference for test execution.
