The aim is the quantitative or qualitative assessment of <a class=\"tc-inlink\" href=\"\/en\/corrosion-consulting-and-testing\/\">corrosion<\/a> behaviour under defined conditions. Test methods are governed by standards, for example in DIN EN ISO 9227.<\/p>\n<p><strong>Practical relevance:<\/strong> Corrosion tests include salt spray tests, climatic tests, immersion tests or electrochemical measurements. The corrosion rate, mass loss, pitting corrosion or undercutting of <a class=\"tc-inlink\" href=\"\/en\/materials-engineering\/coating-technology-processes-and-applications\/\">coatings<\/a> are assessed.
