| Abstract: | This paper summarized and compared test principles， data requirements and extrapolation calculation of two test methods， ISO 9080 and ASTM D 2837， for PE-HD pipes. The calculation process of maximum operating pressure of PE-HD pipes under these two standard systems was further analyzed， which can provide a theoretical reference of design for pipeline in different applicable areas. |
