The internal pressure creep rupture test is a test method for determining the strength of thermoplastic pipes. The test samples are exposed to a constant, internal hydrostatic pressure at a constant environmental temperature either for a predetermined time or until failure. The stress duration depends on the tension generated by the internal pressure and the temperature. The complete 1799 CompactLine set offers 5 test stations and one test bath in one housing. It is ideal for beginners and customers with a low test volume. The compact design offers a simple way of performing reliable tests in an efficient manner.
