Purpose of degradation tests
WebDegradation tests of hydrogel samples were carried out and G-1 hydrogel, which contained the least amount of GA, degraded more rapidly than the others. G-2 hydrogel was chosen for immobilization studies and this procedure was carried out by activation of the hydrogel disc with N-(3-dimethylaminopropyl)-N-ethylcarbodiimid (CDI) coupling agent. WebThis part of ISO 10993 describes two test methods to generate degradation products, an accelerated degradation test as a screening method and a real-time degradation test in a simulated environment. For materials that are intended to polymerize in situ , the set or cured polymer is used for testing.
