摘要

This paper describes the key features of high performance bimodal PE 100 materials, whichrnhave a unique combination of the highest pressure rating for a PE material, outstanding resistancernto SCG (slow crack growth) and outstanding resistance to RCP (rapid crack propagation). Wernwill review the higher pressure rating of PE 100 materials obtained from ISO 9080 and ISOrn12162 called the MRS (minimum required strength) and compare it to the North Americanrnpressure rating method called the HDB (hydrostatic design basis) obtained from ASTM D 2837.rnWe will then review the changes that the Plastics Pipe Institute (PPI) members are making tornseveral ASTM standards so that these PE 100 materials can achieve the same higher pressurernratings of the ISO method using ASTM standards. The new pipe material designation code forrnthese PE 100 materials using the new ASTM terminology will be PE 4610. Finally, we will showrnthat the pipe cost for the traditional PE materials (PE 2406 and PE 3408) is actually higher thanrnthe new high performance PE 4610 materials. These high performance PE 100 materials ratedrnusing the ISO method not only have all the benefits we will describe, but they also have thernlowest cost.
