They provide information on the compatibility of the elastomers with the tested media and their chemical resistance. Immersion tests are often indispensable when selecting materials for new applications.<\/p>\n<h4>The immersion test<\/h4>\n<p>Many standards and test specifications describe testing methods for testing the chemical resistance and determining the behaviour of elastomers in contact with liquids. These include DIN ISO 1817, ISO 1817, VDA 675 301, VDA 675 302, VDA 675 303, VDA 675 304 and VDA 675 305.<\/p>\n<p>Immersion tests always follow the same basic principle, regardless of the standard. First, certain material characteristics are determined in the original state, such as hardness and density, compression set or tensile strength, and the volume of the test specimen is recorded.<\/p>\n<p>Then the test specimens are completely immersed in the defined medium and left there for a given time at a predefined temperature. The exact immersion conditions are specified in the individual regulations. For tests with highly volatile media above boiling temperature, we have a large number of autoclaves available for this purpose.<\/p>\n<p>After completion of the immersion, the test specimens undergo the same measurements as prior to the media tests.<\/p>\n<p>Based on the changes in material properties and volume compared to the original parts, it is possible to make statements about chemical or physical reactions of the elastomer in contact with the media:<\/p>\n<ul>\n<li>Influence by swelling or extraction (increase or decrease in volume)<\/li>\n<li>Change in hardness ( brittleness or softening)<\/li>\n<li>Change in the compound&#8217;s chemical structure as a result of chemical attack<\/li>\n<\/ul>\n<p>We carry out immersion tests in oils, fuels, coolants, refrigerants, superheated steam and many other media.
