Subject of the standard: | This document establishes a system of designation for thermoplastic PE-UHMW materials, which can be used as the basis for specifications. For the purposes of this document, PE-UHMW materials are polyethylene materials having a melt mass-flow rate (MFR) of less than 0,1 g/10 min, measured at 190 °C and 21,6 kg load. NOTE It has been confirmed that the melt volume-flow rate (MVR) is useful for characterizing some PE-UHMW materials (e.g. pipe materials) under the test condition of 230 °C/21,6 kg and bore diameter of die with 3,628 mm (see ISO 21304-2). |
