The scope of this paper is to clarify the various pipe material designation codes and other terms (PE 4710, PE 4710 PLUS, PE 100, PE 100 RC and PE 100+) that are used in the piping industry for high density polyethylene (HDPE) materials. These are the benchmark “high performance” HDPE materials used worldwide for a variety of plastic piping applications. In this paper, I will first describe the two pressure ratings methods, ASTM D 2837 and ISO 9080, and the corresponding pipe material designation codes that are used throughout the industry. I will then review the properties for each HDPE material, and the requirements for its pipe material designation code. I will explain how these HDPE pipe material designation codes are similar and how they are different. I will compare the pressure ratings for each HDPE material using the appropriate design factor or design coefficient. Finally, I will discuss PPI TR-4 and the listing of PE 4710 and PE 100 materials on the PPI website, the PE 100+ Association and the listing of PE 100+ materials on the PE 100+ website, and the new terms PE 4710 PLUS and PE 100 RC.
