Only Eq 1 listed in 3. Work Item s – proposed revisions of this standard. 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. Sampled specimens shall be tested for dilute solution viscosity.

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. Note 1—This standard and ISO address the same subject matter, but differ in technical content.

It is the responsibility d402 the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. 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.
