摘要：This research deals with study of the possibilities of the creep properties measurement on dedicated devices for the creep measurement and on devices, which enable the creep properties measurement. A comparison of these two different measurement methods show the influence of boundary conditions on the measurement result. Simultaneously, the effort to shorten the long-term tests, because of time saving during research and development of new materials, is confronted here. Radiation crosslinking samples of high-density polyethylene (HDPE), which enable the change of the internal structure to the spatial network by the influence of beta radiation, were chosen as an example for comparison.
