Only Eq 1 listed in 3. This specification provides for the identification of virgin, unmodified homopolymer ultra-high-molecular-weight polyethylene UHMW-PE molding and extrusion plastic materials in the form of powder, granules, or pellets. ISO provides a classification system based on various characteristics and a range of viscosity numbers determined in accordance with ISO The melt flow asgm in accordance with test method D cannot be determined for this material because ultra high molecular weight polyethylene does not have a melt x4020.

Application of this test method shall be limited to the characterization of virgin, unmodified UHMW-PE resins, not commercially processed products. This specification is not intended to differentiate between various molecular weight grades of commercially available UHMW-PE, nor does it function to provide specific engineering data for design purposes.

This standard does not purport to address all of the safety concerns, if any, associated with its use. It is advised that the user be s4020 with Test Method D before attempting to use this test method.

The elongational stress method is invalid on a previous thermally-processed material due to possible crosslinking. Sampled specimens shall be tested for dilute solution viscosity. This identification is made in such a manner that the seller and purchaser can agree on the acceptability of different commercial lots or shipments. It is not equivalent to ISO in any other measurement or section X5.

This test method specifies the same type of pendulum impact test machine as that given in Test Method D but introduces a much higher degree of stress concentration into x4020 specimen by double notching with a razor blade. The values given in parentheses are for information only.
