This part of IEC 61234 describes the test method for the determination of the hydrolytic stability of moulded thermosets made of room temperature or oven-curing reaction resins when subjected to the simultaneous influence of water and high temperature. With this test method, the irreversible change of mechanical and electrical properties is measured, but no mechanical stress is imposed on the test specimens.
