Polyethylene pipe produced from resins meeting the criteria for the PE 100 designation were first introduced on an international scale in the late 1980’s. Since, that time these piping products have grown to become recognized as the international standard for longterm performance in the use of polyethylene pipe. The success that these piping products have realized has been predicated on three specific performance properties : long-term hydrostatic strength, exceptional resistance to slow crack growth and an unparalleled resistance to failure by rapid crack propagation. This paper will examine these three properties in relationship to the testing and performance criteria of the North American ASTM-based standards system and introduce to the international community how the PE 100 quality of piping materials is being introduced within the North American system with a material designation of PE 4710. The paper will conclude with a brief analysis of the significance of this evolution within the North American standards system and the potential impact that the use of these products will have in the years ahead.
