Polyethylene (PE) pipes and fittings — Designation of polyethylene, based on nominal density and melt flow index

Tubes et raccords en polyéthylène (PE) — Désignation du polyéthylène, basée sur la masse volumique nominale et sur l'indice de fluidité à chaud

Abstract / scope

Polyethylene material for pipe production ist designated in terms of a figure code. The first group of figures consists of the second and third significant figure of nominal density, the second group consists of the melt flow index multiplied by 100.
