AB - This paper highlights the changes of polyethylene behaviour during various  loading rate as well as the influence of test temperature on the material  characteristics. Passive infrared thermography (IRT) method and a high speed  infrared camera were used to observe the temperature changes of the sample  surface during the tests. The experimental program was carried out on samples  taken from PE80 polyethylene gas pipes with simulated imperfections with  bilateral V-notch, U-notch and central hole. Samples have been tensile tested  (TT) and the results are correlated with the temperature distribution of the  samples surface.
