Corrosion Test Standards

Overview of the Main Test Standards

Corrosion

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.

Condensation water test DIN EN ISO 6270-2 (old DIN 50 017) - FIAT 50184 vb..
Suitable Units
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) - ASTM B 117 - ASTM B 368 - JIS Z 2371 - FIAT 50180
Suitable Units
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 - TS 6610 EN ISO 3231 - TS 9258 EN ISO 6988 - DIN 50018
Suitable Units
This standard which is also known as "Kesternisch test" 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 - VW PV1210 - TS EN ISO 11997-1 - Daimler PPAP 3002(Filiform) - GM 9540 P - Renault D17 2028 ECC1 - Volvo 423-0014 vb.
