To assess resistance to corrosion in practice, we require data about the corrosion behaviour of the materials and the effectiveness of anti-corrosion protection measures, such as coatings and lacquers, in quantifiable, controlled, real-world corrosive conditions.
Quick corrosion tests can hardly be expected to determine the lifetime of a material in a real environment.
Very often, corrosion tests of this kind are carried out as quality inspections of materials, coatings and lacquers, i.e. as end-of-line quality controls.
However, it is often possible to draw certain conclusions about the anticipated lifetime from empirical examinations.
The closer the practical testing environment comes to the real-life conditions, the greater the value of the corrosion test results and, conversely, the more they deviate from one another, the greater the difference may be, in particular, if a change in the type of corrosion results in a change in the way it acts.
We can perform the following corrosion tests:
