Abstract: This paper introduced the research principles and standards of full-notch creep test (FNCT) as a rapid evaluation method proposed by foreign scholars for the long-term test of slow crack growth resistance of polyethylene (PE) pipe. The FNCT results were described in detail under the geometric shape, surfactant, tensile stress and temperature conditions, and the future development prospects for evaluation of PE gas pipelines with the FNCT technology was also discussed.
