The sample is then weighed and then <br />immersed completely in the desired test medium (closed <br />plastic/steel container). Storage is either at +23°C <br />(standard) or another agreed temperature. After <br />the specified test intervals, the sample is removed from <br />the medium, briefly rinsed with water or isopropanol and <br />then dabbed dry with crepe paper. After reweighing, <br />other parameters (Shore A, mechanical properties) <br />are checked if necessary and the sample is evaluated <br />visually and haptically.</p> <p>Evaluation: <br />The evaluation of the results depends on the intended <br />purpose and the changes that are still tolerated. <br />In general, chemicals that cause no or negligible changes <br />after 7 hours do not present a problem with regard <br />to short-term, sporadic contact with the cured sealant. <br />If there is no relevant change after 3 days, even longer <br />occasional contact is unproblematic. Stability after <br />one week of storage indicates good compatibility with <br />the jointing compound, but is no guarantee of unlimited <br />stability with permanent contact. It should be noted that <br />the temperature can have a strong influence on the result. <br />The data reported is therefore only valid in the range <br />of the measurement temperature (deviations of a few °C <br />are usually not critical).</p> <p>The rights of the buyer with regard to the quality of our materials are based on our terms and conditions of sale and delivery.
