Note 1—This standard and ISO address the same subject matter, but differ in technical content. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Only Eq 1 listed in 3.

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.

It is the responsibility of the user of this standard to establish appropriate safety and health practices awtm determine the applicability of regulatory limitations prior to use. The elongational stress is also be referred to as ZST and flow value, or both.

It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Active view current version of standard. 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.

It is not equivalent to ISO in any other measurement or section. ASTM does not give any warranty express or implied or make any representation that the contents of this abstract are accurate, complete or up to date. 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 the specimen by double notching with a razor blade. This standard does not purport to address all of the safety concerns, if any, atsm with its use.

ISO provides a classification system based on various characteristics and a range of viscosity numbers determined in accordance with ISO Sampled specimens shall be tested for dilute solution viscosity.

The melt flow rate in accordance with test method D cannot be determined for this material because ultra high molecular weight polyethylene does not have a melt flow.
