Accelerated Test Methods for Stress Crack Resistance Evaluation of PE Pipe Grades [PE]

# 1998 Gothenburg

The expanding use of tough high-density polyethylene for gas and water pipes requires the develo~m~ent of new test methods for performance evaluation. This paper investigates the suitability of one of the proposed test methods, the Full Notch Creep Test, as a tool for material performance assessment, quality control and ultimately lifetime prediction of MDPE and HDPE pipes. Optimum test conditions are those lending to plane strain slow crack growth within the shortest failure tinie. Therefore, emphasis has been put on the analysis of the influence of test conditions on failure time and fracture mechanism. Guidelines are proposed in order to get a better understanding of the validity and limitations o f this iiew accelerated test method
