The test standard summaries are for general guidance only. Though believed to be accurate at the time of writing, this may change over time. So this information should not be used as a substitute for referring to a complete test standard, at an appropriate revision level.
Note: the terms salt spray, salt mist and salt fog are all in wide spread use within corrosion test standards. In this context they can be considered to be equivalent and interchangeable terms.
DIN 50 017-KFW
Condensed Water Test Climates
Test specimens are placed in an enclosed chamber, and exposed to a changing climate that comprises of the following two part repeating cycle. 8 hours exposure in a heated, saturated mixture of air and water vapour, at a temperature of +40C and a relative humidity of 100%RH. This is followed by 16 hours exposure to room temperature (+18 to +28C according to DIN 50 014) and a relative humidity of less than 100%RH. The number of cycle repeats and therefore the test duration is variable.
