Several types of test chambers are used to test samples to different corrosion conditions. Using temperature and humidity corrosion conditions are created in the test chamber. By adding aggressive test solution or pollution gas the effect can be intensified.

 
 
 

The most important tests are salt spray tests, condensation water tests and pollution gas tests with high humidity. The methods are performed individually or combined. Different national and international norms and standards are applied.

Important standards

Possible units

Condensation water test DIN EN ISO 6270-2 (old DIN 50017) 

 

Condensed water is generated on the test samples at a test chamber temperature of 40°C. Demineralized water is loaded into the chamber and heated for evaporating. The relative humidity is appr. 100%. Periods of high humidity can be combined with periods of ventilation or cooling down.

Salt spray test DIN EN ISO 9227 (old DIN 50021)

     

This standard describes the spraying of a salt solution in the chamber at 35°C or 50°C. Acetic acid or copper chloride can be added to the NaCl solution to accelerate the reaction. The fine salt fog condenses on the test samples and initiates corrosion. A salt spray chamber according to DIN EN ISO 9227 is supplied with a minimum volume of 400 litres.

Pollution gas test DIN 50018 / DIN EN ISO 6988

     

This standard is a special condensation test with the addition of sulphur dioxide. It is dosed into the test chamber at the beginning of the test.The gas combines with the demineralized water to sulphurous acid. The contaminated condensate causes a chemical reaction which is similar to the acid rain.

Alternation test e.g. VDA 621-415 or VW PV1210  

     

Different producers, associations and institutions have developed standards, which combined periods of condensation climate, salt spray, drying or ventilation. The purpose is to produce real environmental stress.
